# API v1 — full reference

OpenAPI spec: `/openapi.json`

## Auth schemes

### None (public reads)
All `GET` endpoints on `/api/v1/rails`, `/opportunities`, `/leaderboard`, `/partners/tiers`, `/honesty/flags`, `/desk/feed.json`, `/stats/*`, `/health` are public and rate-limited per-IP.

### x402 (premium reads)
Request with `X-PAYMENT: <x402-signed-payload>`. Receiver address advertised in 402 response:

```
HTTP/1.1 402 Payment Required
X-Accepted-Payment: x402
X-Payment-Receiver: 0xRECEIVER
X-Payment-Price-USDC: 0.001
```

Verify payment on Base, attach header, retry.

### Partner bearer (writes)
`Authorization: Bearer <wallet>:<sig>` OR `X-Partner-Wallet: 0x... + X-Partner-Signature: ...`. Signature over canonical message `chenecosystem-partner-auth-v1:{TIMESTAMP}:{METHOD}:{PATH}` where timestamp is within 5 minutes.

```

### Feedback (ADR-015)

## Signing conventions

- **Receipts**: ed25519 over canonical JSON of the receipt body with signature fields zeroed
- **Oath**: personalSign (EVM) or Ed25519 over the oath text with `{WALLET}` + `{TIMESTAMP}` substituted
- **Partner auth**: ephemeral sig over `chenecosystem-partner-auth-v1:{TIMESTAMP}:{METHOD}:{PATH}`, 5-min window
- **API responses (Tier 2)**: ecosystem ed25519 sig over canonical response JSON, returned in `X-Signature` header. Pin our pubkey at `/.well-known/signing-keys.json`

## Error shape

{
  "error": "short",
