Look up smart contract information on Base via x402-paid crypto data intelligence endpoint.
What it does
This endpoint, hosted by Erudite Intelligence LLC at bridge.eruditepay.com, provides crypto data intelligence about smart contracts. You send a POST request with a contract address and receive structured JSON data about that contract. The endpoint is described as "Crypto data intelligence" in its x402 challenge.
Payment is required via the x402 protocol (version 2). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 10,000 base units ($0.01 per call), or USDT on Tron (tron:728126428) at 10,000 base units ($0.01 per call). Payment is facilitated through Coinbase CDP's x402 facilitator for the Base option. The provider, Erudite Intelligence LLC, is a FinCEN-registered MSB.
The input schema is straightforward: a JSON body with an `address` field containing the contract address to query. The output is a JSON object with a `success` boolean and a `data` object. However, the example output shows an empty `data` object, so the exact fields returned are not documented. No OpenAPI spec or detailed API documentation was found — the /docs path returns a 404. This limits confidence in what specific contract information is returned.
Capabilities

- —Low-cost per-query contract information retrieval
Not for
- —Bulk historical blockchain data analysis (no batch endpoint documented)
- —Non-crypto or non-blockchain use cases
- —Users who need detailed documentation before integrating — docs are sparse

Quality
The endpoint is live and returns a valid x402 challenge with schema info, but the output example is empty (data: {}), no OpenAPI spec exists, and the /docs path 404s. The actual contract information fields returned are unknown, making integration uncertain.
Warnings
- —No API documentation available — /docs returns 404
- —Output example contains an empty data object; actual response fields are undocumented
- —The description 'Crypto data intelligence' is vague — exact data returned is unclear
- —Schema only describes input; output schema is minimal
