## Verdicts

**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.

**Skyscanner Travel APIs.** Thirteen documented search APIs cover flights, hotels and car hire behind one `x-api-key` header, with default rate limits published per endpoint and no usage fee. Access needs an approved application, an audience above 100,000 monthly users and a commercial agreement, and the usage guidelines bar live-price calls made without a user action. Booking happens on supplier sites.

## 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

### Skyscanner Travel APIs

1. Send the key in the `x-api-key` header on every call to `https://partners.api.skyscanner.net`. CORS is not supported, so call from a server
2. Create a live search only when a user has given origin, destination and exact dates. Use the indicative price endpoints for open-ended questions
3. Poll `/search/poll/{sessionToken}` until `status` is `RESULT_STATUS_COMPLETE`, and replace earlier results only when `action` is `RESULT_ACTION_REPLACED`
4. Start a new session when a poll returns 400. Flight session tokens last about an hour and hotel sessions at most 15 minutes
5. Pass each `deepLink` to the traveller unchanged, since altered encoding breaks Impact tracking, and never put personal data in `subid2`
