It accepts a POST request with a JSON body containing a token address (or symbol) and returns anomaly data. The endpoint is gated by the x402 payment protocol (v2), requiring per-call payment of $0.01 (10,000 base units of USDC on Base, 6 decimals) or the equivalent in USDT on Tron.\n\nThe endpoint is operated by Erudite Intelligence LLC, a FinCEN-registered MSB. Payment settlement is facilitated through the EruditePay x402 Bridge, which supports 20 blockchains. The x402 challenge confirms two accepted payment rails: USDC on Base (eip155:8453) via the Coinbase CDP facilitator, and Tether USD on Tron (tron:728126428).\n\nDocumentation is sparse — the Bazaar schema embedded in the x402 challenge provides the input/output structure, but no detailed field descriptions for the response beyond a generic `{\"success\": true, \"data\": {}}` example. There is no OpenAPI spec, and the docs.eruditepay.com link referenced on the landing page was not crawled. The actual contents of the `data` object in the response are unknown.","tags":[],"capabilities":["volume-anomaly-detection","token-analytics","base-chain","x402-payment","crypto-intelligence","usdc-payment","tron-usdt-payment"],"categories":["crypto","analytics"],"synonyms":["token volume anomaly","crypto volume spike detection","Base token analytics","on-chain volume analysis","trading volume anomaly","EruditePay volume anomaly","x402 crypto data"],"warnings":["Response schema is opaque: the only example shows {\"success\": true, \"data\": {}} with no field descriptions","No OpenAPI specification available","docs.eruditepay.com was referenced but not crawled; /docs on the bridge returns 404","The endpoint description is generic ('Crypto data intelligence') and does not detail what volume anomaly metrics are returned","Token input field description says 'Token address or symbol' but it is unclear which tokens or symbols are supported"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/token/volume-anomaly","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":"0.450","qualityRationale":"The endpoint is live (402 challenge captured) with a clear payment schema and input format, but the response payload is entirely opaque — the example shows an empty data object.
