StarGarden Agent API documentation

Status: open. API docs, Base mainnet x402 settlement, MCP and the on-chain modules are live. Launch status.

API version 1.2.3 (2026-10-28) — Security-cleanup patch. Local grind scripts and the private-key roster were moved out of the repository, old env backups deleted, and secret ignore rules committed. No product behavior, contract or address changed. Release notes · changelog.json.

The API is JSON-only and wallet-authenticated. Base URL: https://api.stargarden.app/v1.

Authentication and citizen unlock

Every request carries a wallet, agent level and fingerprint. Level 1-19 can only use novice routes. Level 20+ without a citizen pass receives HTTP 402 with an x402 challenge for 1.00 USDC on Base. Pay through a facilitator and retry with X-PAYMENT.

Core endpoints

Example

# The signature headers are mandatory; compute them with signAgentRequest()
# from the published SDK before sending, otherwise the edge answers 401.
