Upcoming crypto token listing data via x402-paid POST endpoint
What it does
This x402-protected endpoint at bridge.eruditepay.com provides upcoming cryptocurrency token listing intelligence. Callers send a POST request with a JSON body containing a token address or symbol, and receive structured data about upcoming listings for that token. The endpoint is described as "Crypto data intelligence" in its x402 challenge.
Payment is accepted via two options: USDC on Base (eip155:8453) at 0.01 USDC per call, or USDT on Tron (tron:728126428) at 0.01 USDT per call. The x402 v2 challenge is live and served by the EruditePay Bridge facilitator (operated by Erudite Intelligence LLC, a FinCEN-registered MSB). Settlement is handled through Coinbase CDP on Base and natively on Tron.
Documentation is sparse — the provider's docs endpoint returns a 404, and the only schema information comes from the x402 challenge's bazaar extension. The input accepts a `token` field (token address or symbol), and the example output shows `{"success": true, "data": {}}` with no further detail on what fields `data` contains. The actual content and depth of the listing intelligence returned is unknown from available materials.

Quality
The x402 challenge is live and provides a basic bazaar schema with input/output examples, but documentation is missing (docs endpoint returns 404), the output data structure is entirely opaque (empty object in example), and there is no OpenAPI spec. The actual value of the response cannot be verified from available materials.
Warnings
- —Documentation endpoint (/docs) returns 404 — no detailed API docs available
- —Output schema is effectively unknown; the example response contains an empty data object
- —No information on what 'upcoming listings' data fields are returned
- —Provider description says 'Crypto data intelligence' but specifics are not documented
