What it does

This endpoint at bridge.eruditepay.com provides DEX (decentralized exchange) pair data for tokens on the Base blockchain. It accepts a POST request with a JSON body containing a token address (or pair identifier) and returns pair information. The endpoint is gated behind the x402 payment protocol, requiring per-call payment of 0.01 USDC on Base (eip155:8453) or 0.01 USDT on Tron before data is served.

The endpoint is operated by Erudite Intelligence LLC, which also runs an x402 payment facilitator bridge supporting 20 blockchains. The facilitator is registered as a FinCEN MSB (BSA ID 31000324258137) and operates non-custodially. Payment is facilitated via Coinbase CDP for the Base network option.

Documentation for this specific data endpoint is sparse. The x402 challenge confirms the endpoint is live and describes itself as "Crypto data intelligence." The Bazaar schema embedded in the challenge specifies the input as a JSON body with a `token` field (a token address or pair identifier), and the output as a JSON object with `success` and `data` fields. No detailed field-level documentation for the response data was found, and the example output shows an empty `data` object, so the exact structure of returned pair information is unknown.

Quality

The endpoint is confirmed live via a valid x402 402 challenge with embedded Bazaar schema, but documentation is very thin. The response data structure is unknown beyond a stub example with an empty object. No OpenAPI spec, no detailed docs pages (all return endpoint_not_found), and the endpoint's exact capabilities must be inferred from its URL path and sparse description.

Warnings

  • —No detailed documentation available — /docs, /api, /pricing, /README all return endpoint_not_found errors.
  • —The example output in the Bazaar schema shows an empty data object, so the actual response structure is unknown.
  • —Price is inferred as $0.01 per call based on amount=10000 with USDC (6 decimals), but this is not explicitly documented.
  • —The endpoint description is generic ('Crypto data intelligence') and does not detail what pair fields are returned.
