  description: 'FastAF is a web data API for AI agents: Google SERP, Maps, ecommerce, web scraping, AI extraction, screenshots, news, jobs, research, public profiles and video transcripts. Use prepaid API keys or account-free x402 v2 payments.'
  x-guidance: 'Use GET /x402/v1/{endpoint} with query parameters (not POST or a JSON body). Choose serp for Google search, maps for places, news/shopping/scholar/jobs for specialized search, ai for Google AI Mode, amazon/youtube for their resource variants, linkedin/x for public profiles, walmart/zillow/ebay for structured commerce or listings, scrape for public HTML or markdown, and screenshot for images. Use the dedicated zillow and ebay endpoints instead of scrape for those sites. The q and lang aliases are accepted for query (search_query on YouTube) and language. Send a valid unpaid request first; read the x402 v2 PAYMENT-REQUIRED header, sign with an x402 client such as @x402/fetch, and retry the identical URL with PAYMENT-SIGNATURE. USDC payment uses the network and amount in that live challenge; no API-key authentication is needed. Only successful results are settled; inspect PAYMENT-RESPONSE for the receipt. Prices here are decimal USD, while the challenge uses USDC atomic units (six decimals). Dynamic prices depend on advance_search (serp), resource (amazon/youtube), or rendering, proxies/country and AI extraction (scrape). Scrape site defaults, including Booking rendering and Reddit feed mode, are applied before quoting. A bare unsigned URL returns a default-variant discovery quote only: add valid parameters and request a new challenge before paying. Unpaid HEAD probes also return PAYMENT-REQUIRED with no body; use GET, not HEAD, to pay for data. Invalid parameterized requests and blocked targets return 400; payment headers never bypass validation. Never reuse a settled signature for a new call. Respect Retry-After on rate/capacity errors. For the separate prepaid-key API and authenticated credit-pack top-up, see /v1/openapi.json. Get a free API key at https://fastaf.co/signup/ with an email address, terms acceptance and browser verification. No card is required. POST /public/signup sends an email confirmation link and sets a dashboard session cookie; it does not return an API key. Follow the emailed GET /public/signin/{token} link, then create a key in the dashboard (POST /v1/keys with the session cookie). The key is shown only once. Email confirmation unlocks 2 free calls per account in total, not per day, shared across all keys and all offered REST/MCP endpoints, valid for 12 months; failed calls restore their slot. Unverified trial accounts receive email_verification_required (403) before any data call or trial reservation. Signups are limited per IPv4 /24 or IPv6 /64 network per UTC day (default 3); 429 means retry after the reset. GET /v1/usage reports free_requests_remaining separately from balance_credits. POST /v1/signup is retired and always returns 410 signup_disabled. Agents without an inbox can use /x402/v1/{endpoint} without an account.'
