The table + column schema for the onchain-sql tool - every queryable table (base.events, base.transactions, base.blocks, base.decoded_user_operations, base.transaction_attributions, solana.instructions, …) with its columns and types. Fetch once, then write SQL with confidence.

Parse and normalize an HTTP/HTTPS URL into agent-ready structured components

Validate JSON text and return parsed type plus normalized JSON when valid

End-to-end smoke test for x402 clients: returns a greeting plus the settlement timestamp, so an agent can prove its payment path works before spending on real data.

Inline every local `$ref` in an OpenAPI 3.x or Swagger 2.x document so downstream tools see a self-contained spec. Resolves `#/components/...` (OpenAPI) and `#/definitions/...` (Swagger) JSON-pointer refs anywhere in the document, including inside components themselves. Per-branch cycle detection: if A→B→A, the second A is left as a `$ref` and recorded under `circular`. External refs (http://, file://, ./other.yaml) are never fetched - they're reported under `external` and left as-is.
