It returns historical gas data including 1-hour, 6-hour, and 24-hour averages, percentile breakdowns (P25, P50, P75, P95), min/max values, trend detection (rising, falling, or stable), and a prediction of the best time to submit transactions for lower fees.\n\nThe endpoint is accessed via HTTP GET and accepts query parameters such as `chain=base`, `hours=24`, and `demo=true`. A free demo mode is available (up to 10 calls per IP per hour) by appending `?demo=true`. Paid access costs $0.005 per call, settled in USDC on Base (x402 protocol) or pathUSD on Tempo (MPP protocol). No API keys or subscriptions are required — payment is handled inline via the x402 `X-PAYMENT` header or MPP `Authorization: Payment` header.\n\nThe endpoint is part of the httpay.xyz marketplace, which hosts over 300 pay-per-call API endpoints across categories like crypto, DeFi, utilities, and web scraping. Integration options include the x402-fetch npm package, the @httpay/mcp server for Claude/Cursor agents, or direct curl with payment headers.","tags":[],"capabilities":["gas-price-analytics","historical-averages","percentile-analysis","trend-detection","best-time-prediction","base-l2","x402-micropayment","mpp-payment","demo-mode","pay-per-call"],"categories":["crypto","analytics"],"synonyms":["gas tracker","gas price history","Base gas fees","gas cost estimator","gas trend analysis","EVM gas analytics","L2 gas monitor","transaction fee optimizer"],"warnings":["No OpenAPI schema available for this specific endpoint — output fields are inferred from the description only","The example_response_json is fabricated based on the endpoint description; no real response sample was captured","Documentation pages (/docs, /pricing, /README) all return 404","robots.txt disallows /api/ crawling (except specific paths), so automated discovery is limited","Query parameters (chain, hours) are mentioned in the description but not formally documented in the schema"],"endpointUrl":"https://httpay.xyz/api/gas-tracker-advanced","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","chainId":8453,"version":"2"},"payTo":"0x5f5d6FcB315871c26F720dc6fEf17052dD984359","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://httpay.xyz/api/gas-tracker-advanced","extensions":{"bazaar":{"info":{"input":{"type":"http","method":"GET","queryParams":{}},"output":{"type":"json","example":{"description":"Advanced Gas Tracker for Base — historical gas analysis with 1h/6h/24h averages, percentiles (P25/P50/P75/P95), min/max, trend detection (rising/falling/stable), and best time to transact prediction.
