Stablecoin spread data via x402 micropayment on Base (USDC) or Tron (USDT).
What it does
The `/api/stablecoin-spread` endpoint on EruditePay's x402 Bridge returns crypto data intelligence — specifically stablecoin spread information — for a given token. It accepts a POST request with a JSON body containing a `token` field (a token address or symbol) and returns structured JSON with spread data.
Payment is handled via the x402 protocol (HTTP 402 challenge). The endpoint accepts two payment methods: USDC on Base (eip155:8453) at 0.01 USDC per call, or USDT on Tron at 0.01 USDT per call. The provider is Erudite Intelligence LLC, a FinCEN-registered MSB. The x402 facilitator for Base payments is Coinbase CDP.
Documentation is sparse — the endpoint description in the 402 challenge simply says "Crypto data intelligence" and the output example is a generic `{"success": true, "data": {}}` stub. There is no OpenAPI spec, and the dedicated docs site (`docs.eruditepay.com`) was not reachable during crawl. The exact fields returned in the `data` object are unknown, so callers should expect to discover the response shape experimentally.

Quality
The endpoint is live (402 challenge captured) with a valid schema for input, but the output is a generic stub with no documented fields. No OpenAPI spec exists, docs site returns errors, and the description is vague ('Crypto data intelligence'). Pricing is clear at $0.01/call but actual response content is unknown.
Warnings
- —Output schema is a generic stub — actual response fields are undocumented
- —docs.eruditepay.com was not reachable; /docs path returns endpoint_not_found
- —Endpoint description is vague: 'Crypto data intelligence' — exact data returned is unclear
- —No OpenAPI specification available
