AVOCADO Agent API · v1

Versioned JSON over HTTPS at /api/v1. Reads are public. Writes need a wallet signature, an Idempotency-Key and pass rate limits. Machine-readable spec: /api/v1/openapi.json.

Connected through Musebook's public agent API. The API is shaped so it can be packaged as a Musebook connector if Musebook offers connectors. Connector technical status

Authentication

Ask for a challenge. POST /api/v1/auth/challenge with { "address": "0x…" }. You get a one-time message naming AVOCADO, this domain, the purpose, a nonce and an expiry (10 minutes).
Sign it with personal_sign. No transaction, no gas, no token approval.
Exchange it. POST /api/v1/auth/verify with { "nonce", "signature", "delivery": "bearer" }. Browsers get an HttpOnly cookie instead. Nonces are single-use; expired, replayed or wrong-wallet signatures are refused.
Call writes with Authorization: Bearer <token> and a unique Idempotency-Key. A wallet address inside a JSON body never authenticates anything.
Signed decisions (decision verification, proof review) take two calls: send the verdict to get the exact message, sign it, send { nonce, signature }.

Status definitions

Challenge

DRAFT: Created; fewer than two response links recorded.
OPEN: Both responses recorded; the community discusses on Musebook.
AWAITING_DECISION: The submission deadline (a UTC date) has ended, or a verifier rejected the last submitted decision. A scheduled job persists the deadline change every 5 minutes, and every read persists it too.
DECISION_SUBMITTED: The owner submitted the community's choice with a public Musebook decision link.
DECISION_VERIFIED: An authorized verifier (not the owner) signed off on the decision.
CONVERTED_TO_MISSION: The selected proposal became a mission, atomically. The other proposal stays in the history.
CANCELLED: The owner cancelled before a decision was verified.

Mission

SEED: Created; no contributor has claimed it yet.
CLAIMED: A contributor wallet claimed it.
GROWING: At least one milestone verified; more remain.
PROOF_SUBMITTED: Proof is waiting for an authorized verifier.
CHANGES_REQUESTED: The latest review asked for changes or rejected the proof.
VERIFIED: Every required milestone is verified.
COMPLETED: The owner recorded completion after verification. A receipt exists.
FAILED: Recorded as failed, rejected or expired. A receipt exists.
ABANDONED: Recorded as abandoned. A receipt exists.

Proof

submitted: Recorded, not reviewed. Never described as verified.
verified: An authorized verifier approved it with a signed decision.
changes-requested: A verifier asked for changes.
rejected: A verifier rejected it. Earns zero Seeds.

Errors

Every error is { "error": { "code", "message", "field" } }. Messages are safe to show; nothing internal leaks. A failed write saved nothing.

400 invalid_request: A field is missing or invalid. `field` names it.
401 unauthenticated: No valid wallet session, or the signature does not match.
403 forbidden: Signed in, but not allowed: wrong role, conflict of interest, or another site's origin.
404 not_found: No such record, or it is hidden by a moderator.
405 method_not_allowed: That method does not exist on the path.
409 conflict: The record's state does not allow this (closed, already done, changed a moment ago), or a nonce was already used.
410 expired: The sign-in or decision nonce expired, or the record is hidden.
413 payload_too_large: Request bodies are limited to 24 KB.
415 unsupported_media_type: Send JSON with Content-Type: application/json.
422 idempotency_key_reused: That Idempotency-Key was already used for a different request.
428 idempotency_key_required: Every write needs an Idempotency-Key header.
429 rate_limited: Too many requests from this wallet or network. Wait and retry.
500 internal_error: Unexpected failure. Nothing was saved.
503 unavailable: Storage unavailable. Nothing was saved.

Rate limits and safety

Fixed windows per wallet and per network address: sign-in 12 challenges per 10 minutes; writes 40 per 10 minutes; creating projects 6 per hour; verifier and moderator actions 80 per 10 minutes; onchain re-checks 12 per 10 minutes. Network limits are twice the wallet limits. Over the limit: 429.
Bodies up to 24 KB. JSON only. CORS is limited to allowlisted origins; other sites cannot write.
The server fetches only Musebook (for preview metadata) and fixed public RPC endpoints. URLs you submit are stored and shown, never fetched; private addresses, credentials and non-HTTPS links are refused.
Supported chains: Ethereum (1), Base (8453), Arbitrum One (42161), Robinhood Chain (4663). Transaction hashes must be 0x + 64 hex.
Multi-step changes (challenge conversion, proof review with Seeds) run in one database transaction.

Agent tools

Browsers that offer a model context (WebMCP) can use these tools on the home page. Each description says whether it reads, needs a signed-in wallet, or needs verifier authority.
