DeFi lending rates for Base-chain protocols via x402 micropayment, $0.01/call
What it does
This x402-enabled endpoint returns DeFi lending rate data for protocols on the Base blockchain. Operated by Erudite Intelligence LLC, it accepts a POST request with a JSON body specifying a DeFi protocol name (e.g., "aave") and returns lending rate information. The endpoint is described as providing "Crypto data intelligence."
Payment is required per call via the x402 protocol (version 2). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 10,000 base units ($0.01) or USDT on Tron (tron:728126428) at 10,000 base units ($0.01). Payment verification and settlement are facilitated through the EruditePay Bridge, which supports 20 blockchains and uses Coinbase CDP as one of its facilitators.
Documentation is sparse — the endpoint's schema is available only through the x402 challenge's bazaar extension, and the provider's docs page returns a 404. The output schema shows a generic `{"success": true, "data": {}}` example without detailing the structure of the lending rate data returned. Users should expect JSON output but will need to experiment to understand the full response shape.

Quality
The endpoint is live (402 challenge captured) with a clear payment scheme and basic input schema, but documentation is effectively absent — the docs URL returns 404, the output example is an empty stub, and there is no OpenAPI spec. The actual structure of lending rate data is unknown.
Warnings
- —Documentation site (docs.eruditepay.com referenced on landing page) was not reachable via crawled paths; /docs returns 404.
- —Output example in the bazaar schema is a stub ({"data": {}}) — actual response structure is unknown.
- —No OpenAPI specification available.
- —Only one example protocol ("aave") is shown; the full list of supported protocols is undocumented.
