Technical details
Endpoint
GEThttps://stabletravel.dev/api/flights/checkin-linksWhen to prefer
Use this endpoint when an agent needs to direct a traveler to the correct online check-in page for a specific airline. Ideal for pre-flight automation workflows where the agent knows the carrier's IATA code and needs to surface the exact check-in URL rather than searching the web.
Side effects
- Invalid or unknown IATA airline code returns empty data or error
- Missing required airlineCode parameter causes validation error
- Unsupported language code may fall back to default or return a warning
- Airline does not have an online check-in page resulting in empty data array
- Payment failure (x402) if USDC balance is insufficient
