Endpoint
GEThttps://api.fastaf.co/x402/v1/flights?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, up-to-date Google Flights fare data as JSON for agent-driven travel planning or fare comparison between any two airports worldwide. It is ideal for AI agents that need to programmatically retrieve and compare flight options without scraping and without booking. Prefer it over general web search endpoints when you specifically need structured flight itinerary and pricing data keyed by IATA codes.
Side effects
- Invalid or unsupported IATA airport codes return an error or empty results
- Missing required parameters (departure_id, arrival_id, outbound_date) cause a 400-level error
- Round-trip requests missing return_date may fail or default to one-way
- Dates in the past or incorrectly formatted dates return no results
- Payment failure or insufficient USDC balance results in a 402 error blocking the call
