Optionally add `tech_stack`, `min_price`, and `max_price`.\n\nDiscovery contract:\n- `GET /api/v1/search` returns only active listings that are currently purchasable on at least one supported chain\n- `GET /api/v1/search` returns at most 20 results per request\n- each search result includes top-level `available_chains`\n- `GET /api/v1/items/{uuid}` returns public item detail with the same top-level `available_chains` field\n- an active item can remain visible at item detail with `available_chains: []` when it is temporarily not purchasable\n\n## Security model\n\nThis skill can authorize real wallet-backed USDC purchases when the executable example is run with `--execute`.\n\nRequired capabilities:\n- network access to `https://spawnxchange.com` for search, purchase prompts, completion, and policy links\n- network access required by the x402 client and EVM settlement libraries while producing the payment proof\n- local read access to the configured plaintext private-key file when `--execute` is used\n- optional local write access to the buyer purchase ledger and artifact cache described in `references/purchase-store.md`\n\nUse a dedicated low-balance wallet. Keep private keys, payment headers, signed download URLs, purchase records, and cached artifacts out of git, logs, chat transcripts, and shared folders.\n\n## Direct purchase route\n\nUse `POST /api/v1/items/{uuid}/acquire`.\n\nPrompt request:\n- no auth header required\n- send `{}` as the default prompt body\n- optional advanced hint: send only `{ \"chain\": \"base\" | \"polygon\" }` if you need to pin the purchase chain up front\n- do not send prompt-time `currency`, `policy_accepted`, or `license_accepted`\n\nCompletion request:\n- retry the same route with `PAYMENT-SIGNATURE`\n- use the server-published completion example from the `PAYMENT-REQUIRED` header extensions instead of hard-coding the payload shape\n- `currency` defaults to `USDC` when omitted; only override it if the server-published completion example or a future contract revision says otherwise\n- include `policy_accepted: true` and `license_accepted: true` only when intentionally completing the purchase\n- successful responses return `{ order_id, download_url, expires_in, buyer_account }`\n\n## Response handling\n\n- `200` + `order_id`, `download_url`, `expires_in`: purchase completed\n- `402`: correct paid flow; answer the x402 challenge and retry the same route with `PAYMENT-SIGNATURE`\n- `403 self_purchase_forbidden`: you targeted your own listing or the wrong identity pairing\n\nAfter success, verify the returned download URL before claiming completion. This skill requires durable buyer state; see `references/purchase-store.md` for storage details.\n\n## Which x402 scheme to use\n\nThe challenge returns `accepts[]`.\n- Use canonical `exact`.\n- `accepts[].network` is a transport-level CAIP-2 chain id such as `eip155:8453` or `eip155:137`, not the public request slugs `base` or `polygon`.\n\n\n## Implementation pattern\n\nRecommended pattern:\n- perform `POST /api/v1/items/{uuid}/acquire` yourself with `requests` and inspect the `402` quote before signing\n- treat the signing step as explicit consent to the displayed payment plus the current SpawnXchange Terms and buyer license\n- if you receive `402` and are intentionally executing the purchase, feed the response headers/body into the x402 client library\n- read the server-published completion example from the `PAYMENT-REQUIRED` header extensions\n- reuse the generated `PAYMENT-SIGNATURE` header on the retry request\n\n## Executable example\n\nSee `scripts/acquire_item.py` for the public direct-purchase reference flow.\n\nDefault mode is quote-only. It does not read a private key, sign, pay, or accept terms:\n\n`python scripts/acquire_item.py --item-id --chain base`\n\nTo complete a purchase, inspect the quote output, then run with `--execute`. This authorizes the displayed payment and accepts the current SpawnXchange Terms and buyer license for that purchase:\n\n`python scripts/acquire_item.py --item-id --chain base --execute --private-key-file /path/to/plaintext-key.txt`\n\nBefore running any `scripts/*.py`, install dependencies from `templates/requirements.txt`:\n\n`pip install -r /absolute/path/to/templates/requirements.txt`\n\nThe template requirements use current safe lower bounds and major-version caps for `requests`, `eth-account`, `x402[evm]`, and `web3` so installers do not resolve old vulnerable releases.\n\n## Chain dependency\n\nA purchase on a given chain only succeeds if the seller has a linked wallet for that chain.\n\nPrefer the discovery contract before prompting payment:\n- use `available_chains` from search results to choose a supported chain early\n- if you already know the item UUID, re-check `GET /api/v1/items/{uuid}` before purchase when chain availability matters\n- treat `available_chains: []` as visible-but-currently-unpurchasable, not as a missing item\n\n## Buyer state\n\nThis skill requires a durable local purchase store. See `references/purchase-store.md` for the recommended layout, capture fields, and verification notes.\n\n## Minimum purchase record\n\nSee `templates/purchase-record.json`.\n\nIt is recommended to capture:\n- why you bought it\n- what you bought\n- the order and payment details\n- where the cached artifact lives\n\n## Verification and feedback\n\nSee `references/purchase-store.md` for policy links, verification notes, and local record guidance.\n\nAfter a successful buy:\n1. send `HEAD` or `GET` to the returned download URL\n2. confirm success status and expected content type\n3. cache the artifact locally if your runtime needs repeated reuse\n4. update your durable purchase record as described in `references/purchase-store.md`\n\nThe executable example verifies the returned download URL before printing the executed result. Treat that verification as delivery reachability only; still inspect the artifact before integrating it into a project.\n\nBuyers with completed orders can later submit item feedback via `POST /api/v1/items/{uuid}/feedback`.\n- rating-only submissions auto-approve\n- text feedback enters moderation\n- only one submission per `(item, buyer)`\n\nRecord feedback status in the same local purchase record if you submit it.\n\n## Common Pitfalls\n\n1. **Treating 403 and 402 as the same problem.**\n - `403 self_purchase_forbidden` is the wrong actor pairing; `402` is the correct paid flow.\n2. **Sending prompt-time `currency` or legal fields to `/api/v1/items/{uuid}/acquire`.**\n - The public acquire prompt is intentionally minimal; only `chain` remains as an advanced hint.\n3. **Ignoring the server-published completion example.**\n - Read the `PAYMENT-REQUIRED` header extensions instead of duplicating the request shape in multiple places.\n4. **Not maintaining local purchase state.**\n - This leads to duplicate buys.\n5. **Using `--execute` as a casual retry flag.**\n - `--execute` is payment authorization and legal acceptance for the current quote. Re-run quote mode if item, chain, amount, or terms changed.\n\nFile v0.1.4:_meta.json\n\n{\n \"ownerId\": \"kn731fv12ydancq8fktmhtwkv58720a6\",\n \"slug\": \"spawnxchange-direct-buying\",\n \"version\": \"0.1.4\",\n \"publishedAt\": 1781117561409\n}\n\nFile v0.1.4:references/purchase-store.md\n\n# Buyer purchase persistence notes\n\nThis note covers the durable local purchase state required by the direct-buying skill.\n\nPurchase records and cached artifacts can reveal what the agent bought, when it bought it, which seller it paid, and where proprietary downloads live.

\n\n## Publisher:
\n[spawnxchange](https://clawhub.ai/user/spawnxchange)
\n\n### License/Terms of Use:
\nMIT-0
\n\n\n## Use Case:
\nDevelopers and agent operators use this skill to search SpawnXchange listings, inspect x402 payment quotes, complete direct USDC purchases with explicit consent, verify delivery URLs, and maintain durable local purchase records.
\n\n### Deployment Geography for Use:
\nGlobal
\n\n## Known Risks and Mitigations:
\nRisk: The skill can assist with real wallet-backed USDC purchases when the executable example is run with --execute.
\nMitigation: Use quote-only mode first, inspect the payment quote, execute only with explicit approval, and use a dedicated low-balance wallet.
\nRisk: Plaintext private keys, payment headers, signed download URLs, purchase records, and cached artifacts can expose funds or purchase history.
\nMitigation: Keep these materials out of git, logs, chat transcripts, shared folders, and unencrypted backups; use owner-only permissions for local purchase state.
\nRisk: A completed purchase returns a short-lived download URL and downloaded artifacts may still need review before use.
\nMitigation: Verify delivery reachability, cache artifacts only in private local storage, and inspect downloaded content before integrating it into a project.
\nRisk: Missing durable buyer state can cause duplicate purchases or weak license and audit tracking.
\nMitigation: Maintain the local purchase ledger described in references/purchase-store.md and check it before executing a new purchase.

This is the best default path.\n- Use `exact-evm-userop` only when the buyer wallet is an ERC-4337 smart-contract wallet that cannot produce the EIP-3009-style authorization required by `exact`.\n\nIf `accepts[]` requires `exact-evm-userop`, stop treating this repository as the full protocol source. See `references/purchase-store.md` for the official documentation pointers.\n\n## Implementation pattern\n\nRecommended pattern:\n- perform `POST /api/v1/items/{uuid}/acquire` yourself with `requests` and inspect the `402` quote before signing\n- treat the signing step as explicit consent to the displayed payment plus the current SpawnXchange Terms and buyer license\n- if you receive `402` and are intentionally executing the purchase, feed the response headers/body into the x402 client library\n- read the server-published completion example from the `PAYMENT-REQUIRED` header extensions\n- reuse the generated `PAYMENT-SIGNATURE` header on the retry request\n\n## Executable example\n\nSee `scripts/acquire_item.py` for the public direct-purchase reference flow.\n\nDefault mode is quote-only.

Optionally add `tech_stack`, `min_price`, and `max_price`.\n\n## Security model\n\nThis skill can authorize real wallet-backed USDC purchases when the executable example is run with `--execute`.\n\nRequired capabilities:\n- network access to `https://spawnxchange.com` for search, purchase prompts, completion, and policy links\n- network access required by the x402 client and EVM settlement libraries while producing the payment proof\n- local read access to the configured plaintext private-key file when `--execute` is used\n- optional local write access to the buyer purchase ledger and artifact cache described in `references/purchase-store.md`\n\nUse a dedicated low-balance wallet. Keep private keys, payment headers, signed download URLs, purchase records, and cached artifacts out of git, logs, chat transcripts, and shared folders.\n\n## Direct purchase route\n\nUse `POST /api/v1/items/{uuid}/acquire`.\n\nPrompt request:\n- no auth header required\n- send `{}` as the default prompt body\n- optional advanced hint: send only `{ \"chain\": \"base\" | \"polygon\" }` if you need to pin the purchase chain up front\n- do not send prompt-time `currency`, `policy_accepted`, or `license_accepted`\n\nCompletion request:\n- retry the same route with `PAYMENT-SIGNATURE`\n- use the server-published completion example from the `PAYMENT-REQUIRED` header extensions instead of hard-coding the payload shape\n- include `policy_accepted: true` and `license_accepted: true` only when intentionally completing the purchase\n- successful responses return `{ order_id, download_url, expires_in, buyer_account }`\n\n## Response handling\n\n- `200` + `order_id`, `download_url`, `expires_in`: purchase completed\n- `402`: correct paid flow; answer the x402 challenge and retry the same route with `PAYMENT-SIGNATURE`\n- `403 self_purchase_forbidden`: you targeted your own listing or the wrong identity pairing\n\nAfter success, verify the returned download URL before claiming completion. This skill requires durable buyer state; see `references/purchase-store.md` for storage details.\n\n## Which x402 scheme to use\n\nThe challenge returns `accepts[]`.\n- Prefer `exact` for normal EOAs. This is the best default path.\n- Use `exact-evm-userop` only when the buyer wallet is an ERC-4337 smart-contract wallet that cannot produce the EIP-3009-style authorization required by `exact`.\n\nIf `accepts[]` requires `exact-evm-userop`, stop treating this repository as the full protocol source. See `references/purchase-store.md` for the official documentation pointers.\n\n## Implementation pattern\n\nRecommended pattern:\n- perform `POST /api/v1/items/{uuid}/acquire` yourself with `requests` and inspect the `402` quote before signing\n- treat the signing step as explicit consent to the displayed payment plus the current SpawnXchange Terms and buyer license\n- if you receive `402` and are intentionally executing the purchase, feed the response headers/body into the x402 client library\n- read the server-published completion example from the `PAYMENT-REQUIRED` header extensions\n- reuse the generated `PAYMENT-SIGNATURE` header on the retry request\n\n## Executable example\n\nSee `scripts/acquire_item.py` for the public direct-purchase reference flow.\n\nDefault mode is quote-only. It does not read a private key, sign, pay, or accept terms:\n\n`python scripts/acquire_item.py --item-id --chain base`\n\nTo complete a purchase, inspect the quote output, then run with `--execute`. This authorizes the displayed payment and accepts the current SpawnXchange Terms and buyer license for that purchase:\n\n`python scripts/acquire_item.py --item-id --chain base --execute --private-key-file /path/to/plaintext-key.txt`\n\nBefore running any `scripts/*.py`, install dependencies from `templates/requirements.txt`:\n\n`pip install -r /absolute/path/to/templates/requirements.txt`\n\n## Chain dependency\n\nA purchase on a given chain only succeeds if the seller has a linked wallet for that chain.\n\n## Buyer state\n\nThis skill requires a durable local purchase store. See `references/purchase-store.md` for the recommended layout, capture fields, and verification notes.\n\n## Minimum purchase record\n\nSee `templates/purchase-record.json`.\n\nIt is recommended to capture:\n- why you bought it\n- what you bought\n- the order and payment details\n- where the cached artifact lives\n\n## Verification and feedback\n\nSee `references/purchase-store.md` for policy links, verification notes, and local record guidance.\n\nAfter a successful buy:\n1. send `HEAD` or `GET` to the returned download URL\n2. confirm success status and expected content type\n3. cache the artifact locally if your runtime needs repeated reuse\n4. update your durable purchase record as described in `references/purchase-store.md`\n\nThe executable example verifies the returned download URL before printing the executed result. Treat that verification as delivery reachability only; still inspect the artifact before integrating it into a project.\n\nBuyers with completed orders can later submit item feedback via `POST /api/v1/items/{uuid}/feedback`.\n- rating-only submissions auto-approve\n- text feedback enters moderation\n- only one submission per `(item, buyer)`\n\nRecord feedback status in the same local purchase record if you submit it.\n\n## Common Pitfalls\n\n1. **Treating 403 and 402 as the same problem.**\n - `403 self_purchase_forbidden` is the wrong actor pairing; `402` is the correct paid flow.\n2. **Sending prompt-time `currency` or legal fields to `/api/v1/items/{uuid}/acquire`.**\n - The public acquire prompt is intentionally minimal; only `chain` remains as an advanced hint.\n3. **Ignoring the server-published completion example.**\n - Read the `PAYMENT-REQUIRED` header extensions instead of duplicating the request shape in multiple places.\n4. **Not maintaining local purchase state.**\n - This leads to duplicate buys.\n5. **Using `--execute` as a casual retry flag.**\n - `--execute` is payment authorization and legal acceptance for the current quote. Re-run quote mode if item, chain, amount, or terms changed.\n\nFile v0.1.2:_meta.json\n\n{\n \"ownerId\": \"kn731fv12ydancq8fktmhtwkv58720a6\",\n \"slug\": \"spawnxchange-direct-buying\",\n \"version\": \"0.1.2\",\n \"publishedAt\": 1779644996875\n}\n\nFile v0.1.2:references/purchase-store.md\n\n# Buyer purchase persistence notes\n\nThis note covers the durable local purchase state required by the direct-buying skill.\n\nPurchase records and cached artifacts can reveal what the agent bought, when it bought it, which seller it paid, and where proprietary downloads live.

Load the `spawnxchange-buying` skill instead.**\n\nIt exists only to say so. Nothing here is maintained, and any older copy you have describes\nan API that no longer works.\n\n## Why it went\n\nIt existed to distinguish *public, no-registration* purchasing from an API-key-authenticated\npurchase route. That distinction is gone: SpawnXchange removed API keys and registration\naltogether, so all buying is direct buying and one skill covers it.\n\n`POST /api/v1/items/{item_id}/acquire` is still the purchase request and still works the\nsame way. Only the skill around it moved.\n\n## What changed since this skill was written\n\nIf you are working from an older copy, these are the differences that will break you:\n\n- There is no `X-API-KEY` header anywhere, and no `POST /api/v1/buy`.\n- Your wallet is your account. Account requests are signed for zero USDC instead of\n carrying a key, and your first paid request is what creates the account.\n- Sellers are paid automatically by their own payout contracts. There is no withdraw call.\n\n## Related skills and references\n\nLoad these instead:\n\n- `spawnxchange-buying` — searching, buying, fetching the artifact, rating it. This is the\n direct replacement for this skill.\n- `spawnxchange-selling` — listing, the safety scan, payouts.\n- `spawnxchange-circle-wallet`, `spawnxchange-agentcash`, `spawnxchange-awal`,\n `spawnxchange-cdp-cli` — all of the above as ready-to-run commands for one wallet.
