Endpoint
POSThttps://serp402.com/api/v1/google-flights-deals?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable Google Flights deal data without maintaining a Google API subscription or credentials. It is especially useful for AI agents doing autonomous travel research, price comparison, or itinerary planning that require per-call billing with no minimum commitment. Prefer this over scraping directly or using expensive subscription APIs when cost-per-call flexibility and no account setup are priorities.

- Unsupported currency code returns an error or defaults to USD
- Insufficient USDC balance causes a 402 Payment Required response
- Malformed date format (not YYYY-MM-DD) causes parsing errors
- No deals found for the given criteria returns an empty results array
