[Pricing](/pricing/) ### FastAF limits * x402 settles in USDC on Base only; heavier options (SERP advance\_search, rendering with premium proxies, AI extraction) need an API key. * Public pages only: login-only, paywalled and private-network targets are refused. **Verified on 2026-10-27.** **Short answer:** serp402 sells a wide catalogue (125 endpoints in its machine-readable listing) at a flat price per call, paid only in USDC over x402. FastAF covers fewer sources but prices each endpoint separately, from $0.003 per call, and also sells prepaid credits for API-key use. ## At a glance FastAF serp402 Catalogue 23 data endpoints 125 endpoints in 19 categories ([serp402.com](https://serp402.com), 2026-10-27) Google search $0.003 per call $0.05 per call (`google-light`, [catalogue](https://serp402.com/api/v1?all=1)) Google News $0.005 per call $0.05 per call (`google-news`) Google Jobs $0.005 per call $0.05 per call (`google-jobs`) Amazon $0.003 per call $0.05 per call (`amazon-search`, `amazon-product`) eBay $0.005 per call $0.05 per call (`ebay-search`, `ebay-product`) Page extraction Scrape $0.005 per call `extract` $0.05 per call Google Flights, Google Patents, Bing $0.005 per call each $0.05 per call each (Google Flights, Google Patents, Bing in the [catalogue](https://serp402.com/api/v1?all=1), read 2026-10-28) Payment x402 USDC on Base, or prepaid credits with an API key x402 USDC on Base or Solana; no API key, account or subscription ([serp402.com](https://serp402.com)) Failed upstream call Never charged Payment cancelled, you are not charged ([serp402.com](https://serp402.com)) MCP Hosted MCP with an API key `serp402-mcp` with a wallet key and spend ceiling Beyond FastAF’s scope none listed Hotels, local and travel data and more, in its catalogue Prices are the `priceUsd` values in serp402’s public catalogue; its pages also list a company-profile endpoint at $0.2 per call.
