authentication:
  style: none
  detail: Public, key-free HTTPS. See authentication/shapeshift-authentication.yml.
idempotency:

      previous query

  applies_to:
  - GET /api/v1/account/{pubkey}/txs
versioning:
  style: uri-path
  detail: /api/v1 base path across all chains. See lifecycle/shapeshift-lifecycle.yml.

  detail: Small custom JSON envelopes per status; not RFC 9457. See
    errors/shapeshift-problem-types.yml.
rate_limiting:
  detail: No rate-limit headers or published limits documented for the hosted API.
realtime:
  detail: A WebSocket surface provides realtime pending/confirmed transaction
    updates. See asyncapi/shapeshift-unchained-webhooks.yml.

    EVM, UTXO and Solana variants share the /api/v1/{info,account,tx,send} core.
