How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The proxied upstream response from the Google Flights autocomplete SERP endpoint, containing an array of matching airport names, city names, IATA codes, and related location metadata for the input query string.
Example use cases
Flight booking search bar autocomplete
“As the user types 'Lon' into the destination field of my flight search app, fetch the Google Flights autocomplete suggestions so I can show them a dropdown of matching airports and cities.”
Validate airport name before booking
“I want to confirm what airports come up when someone searches 'CDG' on Google Flights — can you pull the autocomplete suggestions for that query?”
Discover destination options from partial input
“The user typed 'Mia' as their departure city — fetch the Google Flights autocomplete results so I can present the full list of matching airports and locations to choose from.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-google-flights-autocomplete?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Google Flights-specific autocomplete suggestions (airports, cities, destination names) and want to pay per-call via x402 USDC micropayments without a subscription. Prefer it over scraping or generic SERP APIs when you specifically need the flight-oriented destination/airport lookup that Google Flights surfaces, especially for building travel search UIs or validating user-typed flight destinations.
Side effects
- Payment failure if x402 USDC balance is insufficient — returns 402 Payment Required
- Invalid or missing query parameters — upstream returns empty or error response
- Upstream Google Flights SERP API unavailable — gateway passes through 5xx error
- Malformed path or query object — request not forwarded correctly
- Rate limiting by upstream SERP provider — 429 or throttled response
