Query top DeFi yields on Base via x402-paid API endpoint
What it does
This endpoint returns top DeFi yield data for protocols on the Base network. It is an x402-gated POST endpoint operated by Erudite Intelligence LLC, described as "Crypto data intelligence." Callers send a JSON body specifying a DeFi protocol name (e.g., "aave") and receive yield information in return.
Payment is required per-call via the x402 protocol. The endpoint accepts two payment options: USDC on Base (EIP-155:8453) or USDT on Tron, both at 10,000 base units — which equals $0.01 per request (both USDC and USDT use 6 decimals). The x402 facilitator is Coinbase CDP for the Base chain option. The payment recipient address is 0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1 (Base) or TTikV9JD3xTfk5TDv8HMEvpWmNQS8Fm6Pw (Tron).
Documentation is sparse — the endpoint's output schema only shows a generic `{"success": true, "data": {}}` example, so the exact structure of the yield data returned is not documented. The provider's main site (bridge.eruditepay.com) is primarily about the EruditePay x402 Bridge facilitator service, not about this data endpoint specifically. No dedicated docs page was found for the /v1/base/defi/top-yields route.

Quality
The endpoint is live (402 challenge captured) with a clear x402 payment scheme and input schema, but the output is effectively undocumented — the example response is just {"success": true, "data": {}}. No dedicated docs exist for this data endpoint, and the provider's site focuses on the facilitator bridge, not data products.
Warnings
- —Output schema is a stub — actual yield data structure is unknown
- —No dedicated documentation found for this endpoint (docs.eruditepay.com returned no crawl, /docs returns 404)
- —The example response shows an empty data object, so the real response format is unverified
- —Provider site focuses on x402 facilitator services; this data endpoint appears to be a secondary product
