  API Evangelist enrichment pipeline. Captures our additions on top of the
  harvested spec without mutating it. The upstream spec declares no
  securitySchemes, no operationIds and no tags on most operations; those gaps
  are recorded here rather than patched into the original.

      Read-only HTTP surface. Endpoints return an unsigned transactionRequest;
      signing and broadcast occur in the caller's wallet.
- target: $
  update:
    x-apievangelist-gaps:
    - No securitySchemes are declared, although the API accepts an x-lifi-api-key
      header (see authentication/lifi-authentication.yml).
    - No operationIds are defined on any operation, so operations must be
      referenced by method and path.
    - Only the advanced and gas operations carry tags.
    - No response examples are embedded in the spec.
    - Error responses have empty descriptions and no schema.
- target: $.components.securitySchemes
  description: >-
    Document the API key the service actually accepts. LI.FI omits this from the
    published spec; recorded here as an API Evangelist enhancement, not as a
    provider claim.
  update:
    ApiKeyHeader:
      type: apiKey
      in: header
      name: x-lifi-api-key
      description: >-
        Optional API key. Requests without a key are served at a lower rate
        limit. Obtain a key at https://li.fi/plans/. The hosted MCP server also
        accepts Authorization: Bearer and X-LiFi-Api-Key.

  update:
    x-apievangelist-role: primary
    x-apievangelist-note: >-
      Primary entry point. Returns the optimal route plus a transactionRequest
      ready for signing. Setting toToken to a supported vault or staking token
      activates Composer automatically.
- target: $.paths['/v1/status'].get
  update:
    x-apievangelist-note: >-
      Poll every 10-30 seconds until DONE or FAILED. Substatus distinguishes
      COMPLETED, PARTIAL and REFUNDED outcomes.
- target: $.paths['/v1/quote/contractCall'].post
  update:
    x-apievangelist-deprecation-note: >-
      Deprecated in the upstream spec. Use POST /v1/quote/contractCalls.
- target: $.paths['/v1/advanced/possibilities'].post
  update:
    x-apievangelist-deprecation-note: >-
      Deprecated in the upstream spec. Use GET /v1/connections and GET /v1/tools.
