API Endpoints

10 public REST endpoints at https://pacstac.com. No auth required.

POST/v1/verify

Verify wallet ↔ asset stewardship

Check whether a wallet controls a domain, ENS name, X handle, YouTube channel, Instagram account, GitHub account, GitLab account, NPM package, PyPI package, Hugging Face repository, OCI image repository, Bluesky profile, LinkedIn profile, or OpenClaw agent. Supports point-in-time queries and freshness constraints.

Input: wallet (chain + address), asset (type + ref), optional asOf, optional require (maxAgeSeconds, notRevoked)

GET/v1/wallet/{address}

Look up wallet trust data

Returns trust score, network membership, active status, and namespace information. Free tier returns basic data; detail='full' returns premium data (trust level, total points, verified counts, namespace breakdown) via x402 payment.

Input: address, optional detail ('basic' | 'full')

POST/api/v1/wallets

Batch look up up to 100 wallets

Look up multiple wallets in a single request. Same data as lookupWallet but batched for efficiency. Returns results array with per-wallet metadata.

Input: addresses (array, 1-100), optional detail ('basic' | 'full')

GET/api/v1/wallet/{address}/attestation

Fetch signed trust attestation

Returns a signed attestation containing the wallet's trust level, total points, active status, and namespace count. Includes an Ed25519 signature and JWKS URL for independent verification. Attestations have a 1-hour TTL.

Input: address

GET/v1/attestations/{id}

Fetch attestation by ID

Retrieve a specific attestation by its unique ID. Returns the full attestation payload with signature for verification.

Input: attestationId

GET/v1/bindings/{id}/events

Fetch binding verification events

Get the verification and attestation event history for a specific binding. Supports cursor-based pagination for large histories.

Input: bindingId, optional cursor (datetime), optional limit (1-200)

GET/v1/.well-known/jwks.json

Fetch JWKS for signature verification

Returns the JSON Web Key Set used to verify attestation signatures. Use this to independently validate that attestations were signed by PacStac.

Input: (none)

GET/api/v1/x402/info

Fetch x402 payment protocol info

Returns x402 micropayment protocol configuration: pricing tiers, supported payment networks, SDK references, and endpoint details for premium API access.

Input: (none)

POST/api/v1/openclaw/bind

Create OpenClaw agent binding

Creates a binding for an OpenClaw agent. Returns a verifyToken and the challenge messageToSign. The agent (or user) signs the message with their wallet, then calls openclawVerify.

Input: wallet (required), agentName (optional)

POST/api/v1/openclaw/verify

Verify OpenClaw agent binding

Submit the signed challenge message to complete verification. If status is ALREADY_VERIFIED (HTTP 409), the agent is already verified — treat as success.

Input: agentName, wallet, message, signature, token

## API Endpoints

| Endpoint | Method | What it does |
|----------|--------|-------------|
| `/v1/verify` | POST | Verify wallet ↔ asset (domain, ENS, X, YouTube, Instagram, OpenClaw) |
| `/v1/wallet/{address}` | GET | Look up wallet trust data (free basic / paid full) |
| `/api/v1/wallets` | POST | Batch look up up to 100 wallets |
| `/api/v1/wallet/{address}/attestation` | GET | Fetch signed trust attestation for a wallet |
| `/v1/attestations/{id}` | GET | Fetch attestation by ID |
| `/v1/bindings/{id}/events` | GET | Fetch binding verification events |
| `/v1/.well-known/jwks.json` | GET | Fetch JWKS for signature verification |
| `/api/v1/x402/info` | GET | Fetch x402 payment protocol info |
| `/api/v1/openclaw/bind` | POST | Create an OpenClaw agent binding |
| `/api/v1/openclaw/verify` | POST | Verify an OpenClaw agent binding |

## Common Workflows

**Check if a wallet controls a domain:**
`POST /v1/verify` with `{ wallet: { chain, address }, asset: { type: "domain", ref: { domain: "example.com" } } }`

**Look up wallet trust score:**
`GET /v1/wallet/{address}`

**Get verifiable proof of trust:**
`GET /api/v1/wallet/{address}/attestation` — returns signed attestation with Ed25519 signature

**Onboard an OpenClaw agent:**
1. `POST /api/v1/openclaw/bind` with `{ wallet }` → get verifyToken + messageToSign
2. Sign the messageToSign with the wallet
3. `POST /api/v1/openclaw/verify` with `{ agentName, wallet, message, signature, token }`
