Query DeFi yield data for protocols on Base via x402 micropayment
What it does
This x402-enabled endpoint at bridge.eruditepay.com provides DeFi yield intelligence data for the Base network. By sending a POST request with a protocol name (e.g., "aave"), the endpoint returns yield-related data for that DeFi protocol. Payment is required per-call via the x402 protocol, accepting USDC on Base (EIP-155:8453) or USDT on Tron, at a cost of $0.01 per request (10,000 base units with 6 decimals).
The endpoint is operated by Erudite Intelligence LLC, a FinCEN MSB-registered entity. Payment facilitation is handled through the Coinbase CDP x402 facilitator. The response format is JSON, returning a success boolean and a data object, though the exact structure of the yield data returned is not fully documented — the example output only shows an empty data object.
Documentation is sparse. The crawled docs URL returns a 404, and the only schema information available comes from the x402 challenge's bazaar extension. The input schema accepts a "protocol" field described as a "DeFi protocol name or address," but there is no enumeration of supported protocols or detailed output schema. Users should expect to experiment with protocol names like "aave", "compound", "uniswap", etc., and inspect the returned data structure.

}Endpoint
Quality
The endpoint is live and returns a valid x402 challenge with a bazaar schema extension, but documentation is effectively absent (docs URL returns 404). The output example shows only an empty data object, so the actual yield data structure is unknown. Pricing and input schema are clear from the challenge, but supported protocols and response details must be inferred.
Warnings
- —Documentation URL (https://docs.eruditepay.com/) was not crawled and the /docs path on the bridge returns 404
- —Output data structure is undocumented — the example only shows an empty object
- —No enumeration of supported DeFi protocols is provided
- —Actual yield data fields and their meanings are unknown
