What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of api.chit402.com controls every word below.

Paid chat completions

POST /v1/chat/completions (bot drop-in). Returns a signed receipt: hub, model, amount, verify_url. Cost-plus, quoted, receipted — USDC on Base or Solana. No account. No API key. A wallet that can pay the 402 is enough. Unauthenticated GET or POST {} returns HTTP 402. You hold hub, model, and amount.

llmopenai-compatiblex402usdc
Examples it gives
  • POST /v1/chat/completions with { model, messages }

Paid responses API

POST /v1/responses (bot drop-in). Same x402 + signed receipt as /v1/chat/completions. Accepts input (string or message array), max_output_tokens. Returns Responses-shaped output + Chit receipt with verify_url. Stateless one-shot. Unauthenticated → HTTP 402.

llmresponses-apix402usdc
Examples it gives
  • POST /v1/responses with { model, input: "Hello" }

A2A paid door

POST /a2a-message is the A2A card URL. Same x402 floor and chat fulfillment as /v1/chat/completions. Returns a signed receipt: hub, model, amount, verify_url. No account. No API key. A wallet that can pay the 402 is enough. You hold hub, model, and amount. Unauthenticated POST {} returns HTTP 402. Collected rows are bookable via GET|POST /v1/agents/:agent_id/book.

Examples it gives
  • POST /a2a-message with { model, messages } — same body as /v1/chat/completions

Register agent identity

POST /v1/agents/register is fail-closed: bind an AAWP official or smart-account agentWallet to an integer agent_id using a collected HMAC-valid receipt. Demo receipts do not qualify.

Examples it gives
  • POST /v1/agents/register with { agentWallet, task_id }

Agent spend book

GET|POST /v1/agents/:agent_id/book returns last-N collected spend for that agent_id, plus budget Y (cap), spent, and remaining under a prepaid ceiling. Possession-gated (register session or HMAC). Set budget with POST { session, budget }. Not a public index. You hold hub, model, and amount.

Examples it gives
  • POST /v1/agents/1/book with { session }
  • POST /v1/agents/1/book with { session, budget: "10000" }

erc8004validation
Examples it gives
  • POST /erc8004/validate with { task_id, request_hash, agent_id }

Live model ids
