## Derived signals
- Cumulative settled value per tracked x402 transaction: $0.235. $41,547,691 divided by 176,520,376 tracked x402 transactions. This is a ratio of cumulative public-chain measures, not an estimate of a typical purchase.
- Graded catalog callable share: 78.8%. 3,078 callable services divided by 3,906 services in the latest Graded stats snapshot.
- Valid quote coverage in TOLL·402 August snapshot: 24.8%. 19,259 valid exact-route quotes among 77,809 quote-testable routes. Quote validity does not prove paid fulfillment.
- Endpoints per API in APIs.guru: 43.0. 108,837 represented endpoints divided by 2,529 indexed APIs.
