  title: HelloSafe Travel Insurance Conversion API
  version: 1.0.0
  summary: Price and sell travel insurance from any travel product.
  description: 'A REST API that prices a trip against a multi-insurer travel insurance catalogue and returns comparable offers with their guarantees, then mints a tracked subscription link so the sale is attributed and paid as commission. Built for travel agencies, tour operators, OTAs, booking engines and travel apps that want to add travel insurance without becoming an insurer or holding a distribution licence.


    Every key ships with a free sandbox that returns deterministic fixtures in the exact live response shape, so an integration can be built and tested end to end before a single insurer is called.


    **Authentication** is a per-caller HMAC-SHA256 handshake, server to server. Send three headers:


    - `x-atlas-key-id`: your key id

    - `x-atlas-timestamp`: unix seconds, rejected beyond a 5 minute window

    - `x-atlas-signature`: `v2=` + hex HMAC-SHA256 of `${timestamp}.${METHOD}.${pathname}.${rawBody}`, keyed with your signing secret


    The signature covers the raw request body byte for byte. There is no CORS header on these responses: the signing secret must never reach a browser.'
