Look up known exchange addresses on Base via x402-paid crypto data intelligence endpoint.
What it does
This x402-gated endpoint from Erudite Intelligence LLC provides crypto data intelligence, specifically a lookup of known exchange addresses. It accepts a POST request with a JSON body containing a `query` parameter and returns structured JSON results. The endpoint is live and returns a standard x402 v2 payment challenge.
Payment is accepted in two ways: USDC on Base (eip155:8453) at 0.01 USDC per call, or USDT on Tron (tron:728126428) at 0.01 USDT per call. The x402 facilitator is Coinbase CDP for the Base payment option. The provider, Erudite Intelligence LLC, also operates the EruditePay x402 Bridge facilitator service, which supports 20 blockchains for payment verification and settlement.
Documentation is sparse — the endpoint description in the x402 challenge is simply "Crypto data intelligence," and the bazaar schema provides only a generic `query` string input with a minimal example output (`{"success": true, "data": {}}`). There is no dedicated documentation page for this specific endpoint (the /docs path returns a 404). The exact fields returned in the `data` object and the expected format of the `query` parameter are not documented, so callers will need to experiment to understand the full response shape.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but documentation is extremely thin. The bazaar schema provides only a generic query input and a stub output example. No dedicated docs page exists, and the exact response structure is unknown.
Warnings
- —No dedicated documentation available — /docs returns 404
- —The output example in the bazaar schema is a stub ({"success": true, "data": {}}) and does not reveal actual response fields
- —The query parameter format and accepted values are undocumented
- —Response data shape must be discovered empirically
