    No account and no signup for the public API: payment IS the authorization. A paid operation answers 402
    with an x402 quote; the client signs a Solana USDC-SPL transaction (or an escrow deposit, or a spend-down
    channel voucher) and resubmits with the signed payload in the PAYMENT-SIGNATURE header. Free ($0) models
    need no header at all. Identity is the payer wallet (base58 pubkey) recovered from the signed transaction;
    rate limits key on it. Two Bearer-token schemes exist outside the four-operation contract: organisation API
    keys prefixed solvela_k_ for the enterprise org/team/budget routes, and an admin token for /metrics,
    /v1/escrow/health and marketplace registration. Receipt ids and A2A task ids are bearer capabilities.
    No OAuth 2, no OIDC, no discovery documents on any host.

    accepted: <one entry from the 402 challenge's accepts[]>, payload: { transaction } | { deposit_tx, service_id,
    agent_pubkey } }, where transaction / deposit_tx is a base64-encoded signed Solana versioned transaction.
    Omit the header to receive the 402 challenge quoting the price. (Quoted from the securityScheme description.)

  description: >-
    Organisation-scoped API keys for enterprise accounts (org hierarchy, team budgets, audit logs, usage
    analytics). Keys carry full organisational permissions; the secret is shown once at creation and stored
    hashed. Rate limiting for key auth is per source IP rather than per wallet (docs comparison table).

  description: >-
    Unguessable identifiers that are themselves the credential: the UUIDv4 receipt id returned in the
    X-Solvela-Receipt header (GET /v1/receipts/{receipt_id}; unknown and malformed ids return identical 404s,
    rate-capped per IP) and the A2A task id (tasks/get for ~10 minutes after the last state change). The
    provider documents both as bearer capabilities to be kept secret.
