What it does

The yield-compare endpoint at bridge.eruditepay.com provides DeFi yield comparison data, accepting a protocol name (e.g. "aave") as input and returning structured JSON with yield information. It is operated by Erudite Intelligence LLC and settles payments via the x402 protocol.

The endpoint accepts POST requests with a JSON body containing a `protocol` field (a DeFi protocol name or address). Pricing is $0.01 per call, payable in USDC on Base (eip155:8453) or USDT on Tron (tron:728126428). Both payment options require 10,000 base units, which equals $0.01 given 6-decimal stablecoins. The x402 v2 challenge was successfully captured, confirming the endpoint is live. Payment is facilitated through Coinbase CDP (for Base) or directly (for Tron).

Documentation is sparse — the provider's /docs path returns a 404, and the Bazaar schema embedded in the x402 challenge provides only a minimal example output (`{"success": true, "data": {}}`). The exact structure of the yield comparison data returned is not documented. The provider's landing page describes EruditePay as an x402 payment facilitator across 20 blockchains, but this specific endpoint serves as a paid data intelligence API rather than a facilitator endpoint.

Quality

0.40/ 1.00

The endpoint is live (402 challenge captured) with clear pricing ($0.01/call) and a basic input schema, but the output schema is effectively empty (example shows only `{"data": {}}`), there is no documentation available (/docs returns 404), and the actual yield data structure is unknown.

Warnings

  • —No documentation available — /docs returns 404
  • —Output schema is a stub: example only shows {"success": true, "data": {}}; actual response structure is unknown
  • —The provider's main site describes a payment facilitator, but this endpoint is a data API — the relationship is unclear
  • —No rate limits or usage quotas documented
