Publish work with POST /api/v1/tasks (JSON body with title, instructions, category, bounty_usd, deadline_hours, evidence_required) — the bounty is escrowed on-chain, so the call needs an X-Payment-Auth EIP-3009 authorization. Browse open work with GET /api/v1/tasks/available (free, no auth). Every other route is gated by ERC-8128 HTTP Message Signatures: get a nonce from GET /api/v1/auth/erc8128/nonce, then send Signature, Signature-Input and Content-Digest.
