Query DeFi protocol data on Base via x402-paid endpoint (USDC on Base or USDT on Tron)
What it does
This endpoint provides crypto data intelligence focused on DeFi protocols on the Base network. It is operated by Erudite Intelligence LLC and accessed via the x402 payment protocol. Callers send a POST request with a JSON body specifying a DeFi protocol name (e.g. "aave"), and receive structured JSON data about that protocol in return.
Payment is required per-call at $0.01 (10,000 base units of USDC on Base, or 10,000 base units of USDT on Tron — both 6-decimal tokens). The x402 v2 challenge is facilitated through Coinbase CDP on the Base network path, and a direct Tron path is also available. The endpoint returns a 402 Payment Required response with full x402 challenge details when called without payment.
Documentation is sparse. The provider's landing page describes EruditePay primarily as an x402 payment facilitator (verify/settle bridge across 20 blockchains), but this specific endpoint serves DeFi protocol data rather than facilitator functions. The response schema shows `{"success": true, "data": {}}` as an example, but no detailed field-level documentation for the returned data object is available. The input schema accepts a `protocol` field described as "DeFi protocol name or address." Without richer docs or example responses, the exact scope and depth of the returned data cannot be confirmed.
Capabilities
Use cases
- —Retrieve information about a specific DeFi protocol deployed on Base
- —Agent-driven DeFi research by querying protocol details programmatically
- —Building dashboards or alerts that pull live DeFi protocol data
Fit
Best for
- —AI agents needing on-demand DeFi protocol data with micropayments
- —Developers integrating DeFi intelligence into crypto applications
- —Automated research pipelines that query protocol-level data
Not for
- —Users needing free or high-volume bulk DeFi data (each call costs $0.01)
- —Querying non-DeFi or non-Base-related blockchain data (scope unclear)

"success": true
}Endpoint
Quality
The endpoint is live and returns a well-formed x402 v2 challenge with a clear input schema and example. However, documentation is effectively absent (the /docs path 404s), the example response data object is empty, and there is no field-level documentation for what the endpoint actually returns. Pricing and payment mechanics are clear, but the actual data content is opaque.
Warnings
- —No documentation available — /docs returns 404
- —Example response shows an empty data object; actual response structure is unknown
- —The provider's site primarily describes a payment facilitator, not a DeFi data service — the relationship between the two is unclear
- —No OpenAPI spec or detailed schema for the response payload
