What it does

This x402-gated endpoint from Erudite Intelligence LLC returns fee-earnings data for liquidity pools. You POST a JSON body specifying a token address and blockchain network (e.g. Base, Ethereum, Tron), and the endpoint responds with pool fee-earnings intelligence. The endpoint is described as "Crypto data intelligence" in its x402 challenge.

Payment is required per-call via the x402 protocol (HTTP 402 challenge). The endpoint accepts two payment methods: USDC on Base (eip155:8453) at 0.01 USDC per request, or USDT on Tron (tron:728126428) at 0.01 USDT per request. Both amounts are 10,000 base units with 6 decimals. The x402 facilitator is Coinbase CDP for the Base payment rail. Settlement timeout is 300 seconds.

The input schema accepts a JSON body with `token` (a token address or pair identifier) and `chain` (blockchain network name such as base, ethereum, or tron). The output is a JSON object with a `success` boolean and a `data` object. Documentation beyond the x402 challenge and the Bazaar schema extension is sparse — the provider's /docs endpoint returns a 404, and the example output shows an empty `data` object, so the exact structure of the returned fee-earnings data is not documented in the available material.

The endpoint is live (402 challenge confirmed) with a clear Bazaar schema extension describing input/output. However, documentation is effectively absent (/docs returns 404), the example output contains an empty data object, and the actual structure of fee-earnings results is undocumented. Pricing and payment rails are well-specified.

Warnings

  • —No dedicated documentation available — /docs returns 404
  • —Example output in Bazaar schema shows empty data object; actual response structure is unknown
  • —Response fields and their meanings must be discovered empirically
