  description: 'Per-call priced history and depth endpoints, settled in USDC over the x402 protocol on Solana and Base mainnet
    through the Coinbase CDP facilitator. 13 priced endpoints plus the free catalog at /api/x402, which is the authoritative
    price list. Verified 2026-08-11: the catalog lists 13 endpoints from $0.002 to $0.010, and a priced endpoint returns HTTP
    402. These sell depth and history, never access.'

    note: genuine 404. Provider self-reported it and declined credit for it.
  root_cause: The MCPServer registration was NOT missing from the original profile. Commit d00650f registered it, along with
    an Overlay pointer. refine-openapis rewrote apis.yml on 2026-08-09 at 20:31 — renaming the API, adding the aid, repointing
    OpenAPI at the refined per-tag split — and dropped both `MCPServer` and `Overlay` from properties[] in the process, orphaning
    overlays/bykaranteli-x402-overlay.yaml on disk. Both are restored here, and MCPServer is promoted to common[] where the
    scorer actually reads it. See the roadmap issue on refine-openapis property loss.
  not_credited: APICatalog stays on the API `properties[]` and is deliberately NOT promoted to `common[]`. The agent-readiness
    `well_known_catalog` dimension reads APICatalog from `common[]` and is defined as an RFC 9727 /.well-known/api-catalog
    linkset. ByKaranteli publishes a self-describing manifest at its own path, which is not that, and /.well-known/api-catalog
    returns a verified 404. Promoting it would manufacture credit the provider has not earned. well_known_catalog correctly
    stays false.
