Install and run

Setup complexity: low.

clawhub skill install s17fpem9ms79vcs99cb3mps27x8bd7p6:api3-data-feed-purchase

Node.js workspace detected. Install dependencies securely: run `npm ci --ignore-scripts` to prevent post-install lifecycle triggers from running arbitrary code, then selectively audit the dependency tree.
Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Api3 Data Feed Purchase


## Variables

| Variable | Description |
|---|---|
| `DAPI_NAME` | Exact feed name from the dAPI list (e.g. `ETH/USD`) |
| `CHAIN_ALIAS` | Chain alias from the chain list (e.g. `ethereum`) |
| `CHAIN_NAME` | Human-readable chain name (e.g. `Ethereum Mainnet`) |
| `CHAIN_ID` | Numeric chain ID (e.g. `1`) |
| `DEVIATION` | Deviation threshold — must be exactly one of: `0.25`, `0.5`, `1`, `2.5`, `5` |
| `PROXY_ADDRESS` | Reader proxy contract address — starts with `0x`, exactly 42 characters |

---

# Rules
- **NEVER** read .env files or ask for secrets such as WALLET_MNEMONIC.
- **NEVER** read, list, or search inside `node_modules/`, `pnpm-lock.yaml`, or `pnpm-workspace.yaml`,they are not needed for this skill nor relevant to the user.
- **ALWAYS** use the `exec` tool to run commands. Never use Bash or shell directly.
- **ALWAYS** run scripts from the skill's directory, referenced as `{baseDir}` (the directory named by the `name` field at the top of this file). Prefix every command with `cd {baseDir} &&` to ensure it runs from the correct directory.
- **ALWAYS** substitute actual variable values into every `exec` command before running it.
- **ALWAYS** after asking any question, stop and wait for the user's response. Do not assume a response or continue until the user has replied.
- **ALWAYS** complete the current phase fully before moving to the next. Never skip a phase or assume it is already done.
- Treat affirmative responses as approval (e.g. "yes", "sure", "ok", "go ahead", "yep"). Treat negative responses as rejection (e.g. "no", "nope", "cancel", "stop"). If intent is unclear, ask once more before acting.
- **NEVER** wrap URLs in markdown formatting (backticks, asterisks, brackets, etc.) or add trailing punctuation when sharing them with the user — share the raw URL as plain text so it stays clickable and isn't corrupted with extra characters.
- **ALWAYS** lowercase `<CHAIN_ALIAS>` and the feed/token symbol (e.g. the base of `<DAPI_NAME>`) when substituting them into market.api3.org URL paths (e.g. `https://market.api3.org/ethereum/eth-usd/integrate`), even if the confirmed values are stored/displayed with different casing.

## Phase 0: Introduction

- Introduce the skill: you will walk the user through purchasing an Api3 data feed subscription on-chain, step by step. You will ask for approval before installing packages and before executing the purchase transaction.
- Ask if they are ready to begin and wait for an affirmative response before continuing.

## Phase 1: Package Installation

### Part 1.1

- **You must always run this step. Do not skip it, even if you think packages are already installed.**
- Inform the user that before an

# Api3 Data Feed Purchase

Helper skill for buying Api3 data feed subscriptions from market.api3.org.

## Requirements

- `pnpm`
- `ts-node`
- `WALLET_MNEMONIC` in `.env` (see `example.env`)

## Scripts

- `get-dapis.ts` and `get-chains.ts` to discover supported feeds and networks
- `explore-data-feeds.ts` to inspect provider-reported values for a feed
- `quote.ts` to get a subscription price quote
- `buy.ts` to execute the purchase transaction
- `read-data-feed.ts` to read the deployed reader proxy

## Description:

Purchases Api3 data feed subscriptions from market.api3.org.

This skill is ready for commercial/non-commercial use.

## Publisher:

[api3dao](https://clawhub.ai/user/api3dao)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and operators use this skill to select an Api3 dAPI feed and chain, get a subscription quote, execute an on-chain purchase, and optionally read the deployed reader proxy.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The skill uses WALLET_MNEMONIC to sign a live blockchain transaction for a data feed subscription.

Mitigation: Use only a dedicated low-balance wallet and independently inspect the transaction details before approving the purchase step.

Risk: A valuable recovery phrase could be exposed if stored casually in the skill directory or shared with the agent.

Mitigation: Keep production wallet secrets out of the skill directory and avoid sharing the mnemonic directly in chat.

Risk: The read-data-feed step can target an unintended contract if the reader proxy address is malformed or untrusted.

Mitigation: Run that step only after validating the proxy address as a 42-character hexadecimal Ethereum address that starts with 0x.
