Retrieve top DEX trading pairs on Base chain via x402 micropayment
What it does
This endpoint returns top decentralized exchange (DEX) trading pairs on the Base blockchain. It is operated by Erudite Intelligence LLC under the description "Crypto data intelligence" and is accessed via HTTP POST with a JSON body containing a token address or pair identifier.
The endpoint uses the x402 payment protocol (v2) and accepts payment in USDC on Base (eip155:8453) or USDT on Tron (tron:728126428), each at 10,000 base units — equivalent to $0.01 per request. Payment is facilitated through the EruditePay Bridge, which supports settlement via the Coinbase CDP facilitator on Base. The endpoint is live and returns a proper 402 challenge.
Documentation is sparse: the Bazaar schema embedded in the 402 challenge provides the input/output structure, but no detailed field descriptions or full example responses are available. The output is JSON with a `success` boolean and a `data` object, but the exact shape of the data (pair addresses, volume, liquidity, etc.) is not documented. The provider's docs endpoint returns a 404, so users should rely on the schema in the x402 challenge for integration guidance.

Quality
The endpoint is live and returns a valid x402 challenge with embedded schema, but documentation is effectively absent (docs endpoint returns 404). The output example is a stub with an empty data object, so the actual response shape is unknown. Pricing and payment details are clear from the challenge.
Warnings
- —No detailed API documentation available — /docs returns 404
- —Output example in the 402 challenge contains only an empty data object; actual response fields are undocumented
- —The exact contents of the 'data' field (pair names, volumes, liquidity, etc.) must be discovered empirically
