Query new centralized-exchange token listings via x402 micropayment
What it does
The `/v1/market/new-listings-cex` endpoint, operated by Erudite Intelligence LLC, returns data about new token listings on centralized exchanges. It accepts a POST request with a JSON body containing a `token` field (token address or symbol) and returns structured JSON with listing intelligence. The endpoint is gated behind the x402 payment protocol (v2) and costs $0.01 per call, payable in USDC on Base (eip155:8453) or USDT on Tron.
The endpoint is live and returns a proper 402 challenge. The x402 challenge advertises two payment options: 10,000 base units of USDC on Base (6 decimals = $0.01) or 10,000 base units of USDT on Tron (6 decimals = $0.01). The facilitator used is the Coinbase CDP x402 facilitator for the Base option. The provider describes itself as offering "Crypto data intelligence."
Documentation is sparse — the provider's landing page focuses on the EruditePay Bridge (an x402 payment facilitator), not on the market data endpoints it hosts. There is no dedicated API documentation for this endpoint beyond the inline bazaar schema in the 402 challenge. The example output schema shows `{"success": true, "data": {}}` but does not detail the structure of the `data` object, so the exact fields returned are unknown.

Quality
The endpoint is live and returns a well-formed x402 v2 challenge with a bazaar schema, but documentation is essentially absent — no dedicated docs page, no detailed output schema, and the example response body is a stub. The input schema is minimal (single 'token' field). Pricing is clear at $0.01/call.
Warnings
- —No dedicated API documentation exists for this endpoint; /docs returns 404
- —The example output in the bazaar schema is a stub ({"data": {}}) — actual response structure is unknown
- —Provider landing page focuses on the x402 facilitator service, not on market data endpoints
