> NOTICE — Pre-launch build. Every record here is a dated observation of a real MCP endpoint operated by a third party, rendered from the published archive. Coverage is partial — the figures cover the snapshots in the export this build was made from, not the whole chain and not the whole ecosystem. Claims and badges are not open.

## Identity

Record key: x402-url-extractor-production.up.railway.app/mcp (the normalised endpoint observed)
Registry names (not anchored — no inclusion proof reaches this field): not held in the archive for this endpoint — names are held only from REL-SNAP-013 onward and this endpoint appears in no snapshot from then on, so this is a gap in our data rather than a property of the endpoint; read during the sweep but never written into a published snapshot, and unrecoverable afterwards; fixed forward, not backfilled
Name reported by the server: x402-data-gateway (self-reported, unverified, never used as identity)

Each observation carries a merkle leaf in the snapshot it belongs to. The chain
establishes that a root existed by a given time; it does not establish that any
measurement is true.
