Crypto category performance data via x402 micropayment, $0.01/call on Base or Tron
What it does
The `/v1/market/category-performance` endpoint on EruditePay's Bridge provides crypto market data intelligence. It accepts a POST request with a JSON body containing a `token` field (token address or symbol) and returns category performance data for that token. The endpoint is described as "Crypto data intelligence" in its x402 challenge.
Payment is handled via the x402 protocol (HTTP 402 challenge/response). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 10,000 base units ($0.01) or USDT on Tron at 10,000 base units ($0.01). Payment is facilitated through Coinbase CDP's x402 facilitator on Base, and directly on Tron. The provider is Erudite Intelligence LLC, a FinCEN MSB-registered entity.
Documentation is sparse — the endpoint's output schema only shows a generic `{"success": true, "data": {}}` example, and no dedicated docs page was found (the `/docs` path returns a 404). The exact structure of the returned category performance data is not documented in the available materials. The endpoint is live and responding with a valid x402 v2 challenge.

Quality
The endpoint is live with a valid x402 v2 challenge and clear pricing ($0.01/call). However, documentation is effectively absent — no dedicated docs page exists, the output example is an empty object, and the exact nature of 'category performance' data is undefined. The input schema is minimal (just a token field).
Warnings
- —No dedicated documentation found — /docs returns 404
- —Output schema example contains only an empty data object; actual response structure is unknown
- —The description 'Crypto data intelligence' is vague and the specific fields returned are not documented
- —Cannot verify what 'category performance' actually measures without a successful paid call
