Query newly listed DEX trading pairs on Base chain via x402 micropayment
What it does
This x402-gated endpoint from Erudite Intelligence LLC returns data about new decentralized exchange (DEX) trading pairs on the Base blockchain. Callers send a POST request with a JSON body containing a token address (or pair identifier), and receive structured JSON data about new pairs associated with that token.
The endpoint accepts payment via two channels: USDC on Base (eip155:8453) or USDT on Tron (tron:728126428), both priced at $0.01 per call (10,000 base units with 6 decimals). Payment is facilitated through the x402 v2 protocol using the Coinbase CDP facilitator for Base and EruditePay's own bridge for Tron. The provider, Erudite Intelligence LLC, operates the EruditePay x402 Bridge — a FinCEN MSB-registered payment facilitator supporting 20 blockchains.
Documentation is sparse: the endpoint description is simply "Crypto data intelligence" and the example output is a generic `{"success": true, "data": {}}` stub. The exact fields returned in the `data` object are not documented, so consumers should expect to discover the response shape empirically. The endpoint is live and returning a valid x402 402 challenge.

Quality
The endpoint is live and returns a valid x402 challenge with pricing and schema, but documentation is minimal — the output example is a stub with an empty data object, there is no OpenAPI spec, and the /docs path returns 404. The actual response structure must be discovered empirically.
Warnings
- —Response schema is undocumented — the example output contains only an empty data object
- —No OpenAPI or dedicated documentation available (docs endpoint returns 404)
- —Endpoint description is vague: 'Crypto data intelligence' with no further detail
- —Exact fields and semantics of returned pair data are unknown
