Expedia Group Rapid API vs FlightClaw

Expedia Group Rapid API

Expedia's lodging inventory with shop, price check, book, change and cancel in one API. Partner application and site review before production, no self-serve keys.

FlightClaw

Hosted MCP at mcp.flightclaw.com/mcp with OAuth 2.1, PKCE and dynamic client registration, no API keys. Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.

Expedia Group Rapid API

1. Build the SHA-512 signature from key, secret and the current epoch seconds in that order, per request
2. Send Customer-Ip and the session headers the docs ask for, since fraud checks use them
3. Point everything at test.ean.com until the site review is through; the paths match api.ean.com
4. Follow the links in each response rather than building URLs; price check and book links carry tokens
5. Read the Rate-Limit-Minute-Remaining and Rate-Limit-Day-Remaining headers, since the docs publish no ceilings

FlightClaw

1. Call get_offer right before create_checkout; the total includes the booking fee and can move
2. Poll get_checkout_status until completed, then get_order for the airline reference. A sent link isn't a booking
3. Never ask for card numbers in chat. Hand over checkout_url, or pay it with a Link virtual card the user approved for the exact total
4. Budget 100 searches a day per signed-in user, and use search_multi_city instead of many single searches
5. Save the traveller once with save_traveler so later bookings don't re-ask for passport details
