It accepts a POST request with a JSON body containing a token address or symbol and returns structured JSON data. The endpoint is operated by Erudite Intelligence LLC.\n\nPayment is required per call via the x402 protocol (HTTP 402 challenge). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 10,000 base units ($0.01) per request, or USDT on Tron (tron:728126428) at 10,000 base units ($0.01) per request. Payment verification and settlement are facilitated through the EruditePay Bridge, which supports 20 blockchains and uses the Coinbase CDP facilitator for Base settlements.\n\nDocumentation is sparse — the endpoint description is simply \"Crypto data intelligence\" and the example output schema shows only a generic `{\"success\": true, \"data\": {}}` structure. The exact fields returned in the `data` object are not documented. The input schema accepts a `token` field described as \"Token address or symbol,\" suggesting you can query by either contract address or ticker. No OpenAPI spec or dedicated docs page is available for this specific endpoint.","tags":[],"capabilities":["crypto-token-data","base-chain-analytics","x402-payment","usdc-payment","usdt-tron-payment","top-tokens-lookup","json-api"],"categories":["crypto","data"],"synonyms":["top tokens","token analytics","base chain tokens","crypto market data","token intelligence","EruditePay tokens","on-chain token data","USDC token info"],"warnings":["No OpenAPI or detailed API documentation available; /docs returns 404","Output schema example is a generic stub — actual response fields are undocumented","The endpoint path says 'top-tokens' but the input asks for a single token address, creating ambiguity about what is actually returned","No rate limits or usage quotas documented"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/token/top-tokens","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 valid x402 v2 payment challenge and basic input/output schema.
