# Mempool API Provider Profile | PubFi Discovery > Mempool API is an automation-built public Provider Profile for Mempool public API resources. Discovery has public docs evidence, but PubFi does not certify gateway runtime support for this provider. Source: checked-in public Discovery data plus the exact live Registry snapshot observed for this response. Format: text/markdown; charset=utf-8 Inclusion gate: source.isIndexable is true and readiness_flags.llms_export_ready is true; draft/noindex and LLM-export-excluded records are not emitted as markdown detail pages. Canonical SEO rule: the HTML detail page is the canonical SEO URL; this Markdown route is an agent-readable mirror. Execution authority: current PubFi routeability comes only from /v1/capabilities and the matching runtime /openapi.json. Checked-in editorial status does not make a provider executable. Canonical HTML URL: https://pubfi.ai/discovery/api/mempool Markdown URL: https://pubfi.ai/discovery/api/mempool.md Title: Mempool API Provider Profile | PubFi Discovery Provider: Mempool One-liner: Mempool API public Provider Profile generated from processed evidence. Long description: Mempool API is an automation-built public Provider Profile for Mempool public API resources. Discovery has public docs evidence, but PubFi does not certify gateway runtime support for this provider. SEO description: Mempool API public Provider Profile with processed API evidence and no PubFi gateway certification claim. Public status: unproven Directory status: coming soon Raw claim-safe status: public_source_profile (Provider Profile) Raw claim-safe CTA: Compare sources Editorial posture: public_source_profile (Provider Profile) Editorial CTA: Compare sources Execution boundary: editorial only; runtime status separate Editorial posture reason: This checked-in status describes editorial publication only; it is never PubFi execution authority. PubFi gateway readiness: ready (Available in the active Registry) PubFi gateway summary: The currently installed signed Registry generation contains an executable route for this provider. The same generation drives request matching, runtime OpenAPI, and this public view. PubFi gateway guidance: - Accepted PubFi auth headers: Authorization: Bearer . - Upstream credentials remain server-side; callers send only a PubFi API key. - Use the runtime OpenAPI for the exact typed query, body, and response contract.
