AOTrust — PDR Notarization

Issue a cryptographic proof (PDR) that a digital artifact existed at a specific time. Pay $0.01 USDC on Base or Solana via x402 (MCP). Anchored daily to NEAR blockchain. Publicly verifiable. ONLY invoke when the user explicitly requests notarization or proof-of-existence for a specific artifact. This skill performs a paid external API call ($0.01 USDC, irreversible). Do NOT invoke proactively or as part of unrelated workflows.

# AOTrust — Cryptographic Proof of Existence

## ⚠ Before You Start — Security & Consent

This skill interacts with an **external paid API**. Read this before invoking.

| What leaves your machine | Where it goes | Reversible? |
|--------------------------|---------------|-------------|
| `work_hash` (SHA-256 of your artifact) | api.aotrust.link | No — hash is public in the PDR |
| `agent_sig` + `agent_pubkey` (optional, bilateral) | api.aotrust.link | No — stored in notary ledger |
| EIP-3009 payment signature | Base Mainnet (on-chain) | No — $0.01 USDC, irreversible |

**Rules:**
- **Confirm with the user** before notarizing. Show the artifact hash and ask: "Notarize this for $0.01 USDC?"
- **Never use an unattended wallet.** Payment requires manual approval for every transaction.
- **Do not let the agent manage private keys.** The user signs EIP-3009 manually or via a wallet that requires confirmation.
- The artifact itself is never uploaded — only its hash. But the hash is public in the PDR and on NEAR blockchain.

---

A PDR (Provenance Data Record) is a 239-byte cryptographic receipt proving
that a digital artifact existed at a specific point in time.

Works with any digital artifact:
emails, documents, contracts, source code, AI outputs,
research notes, datasets, photos, logs, sensor readings.

The artifact itself is never uploaded — only its SHA-256 hash.

Anchored daily to NEAR blockchain. $0.01 per proof. No account needed.

## Two Ways to Connect

| Interface | Best for | How |
|-----------|----------|-----|
| **MCP** (recommended for AI agents) | AI agents with MCP support | tools/list → notary_notarize_paid (x402 in-band micropayment) |
| **HTTP API** (for developers) | Direct integration, scripts, CI/CD | POST /notarize → 402 → pay → 200 |

Both interfaces produce the same PDR. Pick one.

---

## Interface 1: MCP (for AI Agents)

### Endpoint

```
https://api.aotrust.link/mcp
```

### Authentication

**None required.** The MCP endpoint works without any token or OAuth flow —
connect and call `tools/list` directly. Free-tier tools (`notary_free`,
`notary_quote`, `notary_verify`) are keyless; paid notarization uses in-band
x402 micropayments (no API key either).

OAuth 2.1 endpoints exist as optional discovery stubs

## Description:

Creates and verifies cryptographic proof-of-existence receipts for digital artifacts when a user explicitly requests notarization.

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

## Publisher:

[gitserge-crypto](https://clawhub.ai/user/gitserge-crypto)

### License/Terms of Use:

MIT-0

## Use Case:

People and developers use this skill to request a timestamped proof for a specific artifact hash and later verify the resulting receipt. Paid notarization requires explicit user consent and a wallet-approved payment.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The artifact hash is sent to AOTrust and may be publicly visible in the proof.

Mitigation: Only submit the hash when the user explicitly requests proof for that specific artifact; do not upload the artifact itself.

Risk: Paid notarization incurs an irreversible $0.01 USDC charge.

Mitigation: Before each payment, confirm the exact hash, destination, chain and charge with the user; require manual wallet approval and never authorize unattended signing.

## Reference(s):

- [AOTrust MCP endpoint](https://api.aotrust.link/mcp)
- [AOTrust HTTP notarization endpoint](https://api.aotrust.link/notarize)
- [AOTrust PDR verification endpoint](https://api.aotrust.link/v1/pdr/verify)

## Skill Output:

**Output Type(s):** [Text, JSON]

**Output Format:** [Text summary with a proof receipt and verification result]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Receipt includes a public artifact hash; paid proofs cost $0.01 USDC.]

## Skill Version(s):

3.9.1 (source: release evidence and skill frontmatter)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
