Data coverage
A metric-by-metric audit of what this site can obtain, what it measures itself, and what stays empty because no honest source exists. Public availability of an API does not mean a number on this site was fetched from it — the availability column says which case applies.
| Metric | Source | Availability | Limitation |
|---|---|---|---|
| Service listing | Official MCP Registry, x402 Bazaar | public API | A listing is the publisher’s claim. It is not a working endpoint and not a sale. |
| MCP server status | own probe · mcp_server_checks | measured by us | A successful handshake proves reachability once. It says nothing about usefulness or uptime. |
| Price per call | registry and bazaar metadata | sometimes public | A quoted price is not the amount charged. Free tiers and token-based billing sit on top. |
| Calls · 30d | platform-reported usage | partial | Only services whose platform publishes counts. Everything else stays empty, never zero. |
| Downloads · 30d | npm registry, PyPI (pypistats) | partial | Installs of the published package — adoption, not revenue and not calls. Only services that ship a package have a number. |
| Payers · 30d | platform-reported usage | partial | Same coverage as calls. One wallet is not one buyer. |
| Value at list price | calls × published price | derived | An upper bound of what those calls would cost. It is not money that moved. |
| Settled payments | own ledger, evidence-classed | only with evidence | Needs a receipt or provider records plus an evidence class. No service qualifies today. |
| Asset price, market cap, volume | CoinGecko | public API | Quoted figures, not audited. Deduplication across categories is our arithmetic, not the source’s. |
| Revenue per service | — | not available | No public source reports what a service earns. We do not infer it from listing position. |
| Market cap per service | — | not applicable | A service has no circulating supply. Market capitalisation exists for tokens only. |
| Buyer identity | — | usually unavailable | Signed payment metadata exists only where the provider records it. |

Endpoints we read
Two metrics exist in the schema but appear nowhere yet because no row carries them: per-day settled value and payer counts from our own ledger. They will appear the day evidence arrives — not before. How each figure is checked: Methodology.
