It is operated by Erudite Intelligence LLC and accessed via the x402 payment protocol. A POST request with a JSON body specifying the target chain (e.g. \"base\", \"ethereum\", \"tron\") returns gas-related chart data.\n\nThe endpoint accepts payment in two ways: USDC on Base (EIP-155:8453) or USDT on Tron, both at $0.01 per call (10,000 base units with 6 decimals). Payment is facilitated through the EruditePay x402 Bridge, which supports the x402 v2 protocol and settles via Coinbase CDP or directly on-chain. The response format is JSON with a top-level \"success\" boolean and a \"data\" object, though the exact structure of the data payload is not documented beyond the example stub.\n\nDocumentation is sparse — the provider's /docs path returns a 404, and the Bazaar schema extension provides only a minimal example output (`{\"success\": true, \"data\": {}}`). The endpoint is live and returning a proper 402 challenge, but without richer documentation or sample responses it is difficult to know exactly what gas chart metrics are included (e.g., historical gas prices, percentiles, time-series data). The provider is a FinCEN-registered MSB (BSA ID 31000324258137) operating a non-custodial settlement model.","tags":[],"capabilities":["gas-analytics","blockchain-data","gas-chart","x402-payment","multi-chain","base-chain","tron-chain","usdc-payment","usdt-payment","json-api"],"categories":["crypto","analytics"],"synonyms":["gas price chart","gas fee analytics","blockchain gas data","base gas tracker","gas cost history","on-chain gas metrics","crypto gas analysis"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return 404","Example output in Bazaar schema is a stub with empty data object; actual response structure unknown","No OpenAPI or detailed schema for the analytics response"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/analytics/gas-chart","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x24c5da6267AEbEBfCBf7B325753C5B2538A5B09B","amount":"3000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t","extra":{"name":"TronTransferAuthorization","version":"1","wrapper":"THGkLBrLY1G5VovZjjK1jP9upyxRdMNL3b"},"payTo":"TSevuRZFjpckeMSSDhQFoiAkPCkckuE5TP","amount":"3000","scheme":"exact","network":"tron:728126428","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live and returns a valid x402 v2 challenge with clear pricing.
