summary: >-
  There is no authentication. The OpenAPI declares no securitySchemes and no security requirement on any
  of its 24 operations; the agent card's auth block is {"type": "none", "header": null} and its
  securitySchemes/security are empty; every read (agent card, x402 catalog, health, metrics, the full task
  list, any task by id) answers anonymously. What gates the paid surface is PAYMENT, in two forms: an x402
  v2 PAYMENT-SIGNATURE header on POST /x402/{skill} (a call without it returns HTTP 402 with a
  PAYMENT-REQUIRED challenge), and for the quote-first task API an on-chain invoice whose memo must equal
  the task id, confirmed by the operator's payment watcher or a checkout-provider webhook. Neither is an
  identity: the agent never learns who the caller is, only that a payment settled. No API keys are issued,
  no OAuth server exists (/.well-known/oauth-authorization-server and /oauth-protected-resource 404), and
  no signup exists.

    challenge: HTTP 402 with PAYMENT-REQUIRED response header (base64 JSON, identical to the body) — x402Version 2, accepts[] of {scheme exact, network, amount, asset, payTo, maxTimeoutSeconds 120, extra}
    settle_header: PAYMENT-RESPONSE (declared in /.well-known/x402.json; not observed — settlement was not exercised)

      accepts[].extra.note — "Send USDC on Base to payTo, then retry with payload.tx_ref = the transaction
      hash. Verified on-chain (receipt success, USDC contract, correct payee, amount >= price) and usable for
      exactly one call." (invoiceBridge true, settlesRealFunds true)
    observed: '2026-09-19 — POST https://a2a.elonsusk.com/x402/util.json.format returned 402 with the header and body above; amount "2000" for a $0.002 skill.'
  - name: Quote-first crypto invoice
    surface: POST /v1/tasks (create_task_v1_tasks_post) or A2A tasks/send on POST /a2a
    flow: create task -> response carries quote {quote_usd, tokens_estimate, pricing} and invoice {amount_usd, asset, address, memo, expires_at, provider, status} -> pay any enabled method with memo = task id -> state moves payment_required -> paid -> working
    methods: [SOL, USDC on Solana, ETH, USDC on Ethereum, BTC]
    confirmation: operator payment watcher (solana_rpc per /healthz) or checkout-provider webhook (NOWPayments, CoinGate via POST /v1/payments/webhook/{provider}); a manual fallback is declared in payment_notes.mode

  - name: Human lead intake
    surface: POST /v1/leads (create_public_lead_v1_leads_post)
    credential: none — contact string 3-240 chars, brief 12-8000 chars, optional budget_usd
    note: The only channel that carries a human identity, and it is free text.
open_operations_of_note:
- operation: list_tasks_v1_tasks_get
  note: Returns every task in the queue with inputs, quotes, invoice addresses and memos, payment notes and results, to anyone. Not a documented feature; an observation.
- operation: mark_paid_v1_tasks__task_id__mark_paid_post
  note: Published in the public contract with no securityScheme. Whether the server verifies tx_ref before honouring it is not stated; treat as operator-side.
- operation: payment_webhook_v1_payments_webhook__provider__post
  note: Inbound provider webhook with no declared signature verification scheme in the contract.
