It is part of a \"Crypto data intelligence\" service accessible via the x402 payment protocol. Callers POST a JSON body containing an Ethereum-style address and receive a JSON response with pool toxicity data.\n\nPayment is required per-call at $0.01 (10,000 base units of USDC on Base, or 10,000 base units of USDT on Tron). The endpoint uses x402 v2 with the \"exact\" payment scheme, settling through the EruditePay Bridge facilitator (backed by Coinbase CDP on Base). The provider, Erudite Intelligence LLC, is a FinCEN-registered MSB.\n\nDocumentation is sparse: the endpoint description is simply \"Crypto data intelligence\" and the example output is a generic `{\"success\": true, \"data\": {}}` stub. There is no detailed schema for the response payload, no explanation of what fields appear inside `data`, and no public docs page was found (the /docs path returns a 404). The endpoint is confirmed live — it returns a proper 402 challenge on POST — but without richer documentation it is difficult to know exactly what intelligence is returned or how to interpret the results.","tags":[],"capabilities":["mev-detection","toxic-pool-analysis","base-chain","contract-address-lookup","x402-payment","usdc-payment","usdt-tron-payment","crypto-intelligence"],"categories":["crypto","defi","security"],"synonyms":["MEV toxic pools","sandwich attack detection","Base DEX pool analysis","liquidity pool risk","MEV bot detection","toxic liquidity","DeFi pool scanner","Base USDC x402"],"warnings":["No public documentation found — /docs returns 404","Response example is a generic stub with empty data object; actual response fields are unknown","Endpoint description is only 'Crypto data intelligence' with no detail on what toxic-pool data is returned","Only Base chain addresses appear supported despite the provider supporting 20 chains for settlement"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/mev/toxic-pools","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1","amount":"8000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live (402 challenge confirmed) with a clear payment schema and input spec, but the response payload is an empty stub, there are no public docs, and the description is generic.
