## Before you call either

### 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
