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.\n\nPayment 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.\n\nDocumentation 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.","tags":[],"capabilities":["crypto-market-data","category-performance","token-analysis","x402-payment","multi-chain-payment","usdc-base","usdt-tron"],"categories":["crypto","market-data"],"synonyms":["crypto category performance","token sector performance","crypto market intelligence","token category data","crypto sector analysis","market category metrics"],"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"],"endpointUrl":"https://bridge.eruditepay.com/v1/market/category-performance","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1","amount":"3000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live with a valid x402 v2 challenge and clear pricing ($0.01/call).
