Get DEX quotes for tokens on Base via x402-paid crypto data intelligence endpoint.
What it does
This endpoint at bridge.eruditepay.com provides DEX (decentralized exchange) quote data for tokens on the Base blockchain. It is operated by Erudite Intelligence LLC and described in the x402 challenge as "Crypto data intelligence." The endpoint accepts a POST request with a JSON body containing a token address (or pair identifier) and returns quote data in JSON format.
Payment is required via the x402 protocol (version 2). The endpoint accepts two payment options: USDC on Base (network eip155:8453) at 10,000 base units ($0.01 per call, since USDC uses 6 decimals), or USDT on Tron (network tron:728126428) at 10,000 base units ($0.01 per call). Payment is facilitated through the Coinbase CDP x402 facilitator for the Base option. The provider is FinCEN MSB registered (BSA ID 31000324258137) and the bridge supports 20 blockchains for settlement.
Documentation is sparse — the /docs path returns a 404, and the Bazaar schema embedded in the x402 challenge provides only a minimal example with a token address field and a generic success/data response shape. The exact structure of the returned quote data (e.g., price, liquidity, slippage) is not documented in the available materials. The endpoint is confirmed live, returning a proper 402 challenge on POST requests.

Quality
The endpoint is confirmed live with a valid x402 v2 challenge and clear pricing ($0.01/call). However, documentation is effectively absent — the /docs path 404s, the response schema example is a stub ({"success": true, "data": {}}), and the input schema only documents a single 'token' field. The actual quote data structure must be inferred.
Warnings
- —No dedicated documentation available — /docs returns 404
- —Response schema example is a stub with empty data object; actual response fields are unknown
- —Input schema only documents a 'token' field; additional parameters (e.g., amount, slippage) may exist but are undocumented
- —No OpenAPI specification available
