# Bilt Travel Portal Search Search [Bilt Rewards](https://www.bilt.com) travel portal via the public REST API. No authentication required for search. Returns both cash prices in USD and Bilt Points cost for hotels and flights. ## Important: Bilt is Whitelabel Duffel Bilt's travel search is built directly on top of [Duffel](https://duffel.com). All evidence points to a complete white-label arrangement, not a partial integration: - Flight offer IDs are `off_XXX`, slices `sli_XXX`, segments `seg_XXX`, aircraft `arc_XXX`, airlines `arl_XXX`. All Duffel ID patterns. - Carrier and aircraft logos served from `assets.duffel.com`. - Hotel loyalty program logos served from `assets.duffel.com/img/stays/loyalty-programmes`. So hotels are Duffel Stays. - JWT `organisation_id: org_0000AaALZyFQ...` is a Duffel auth pattern. - Field names match Duffel exactly: `marketingCarrier`, `operatingCarrier`, `cabinClassMarketingName`, `fareBasisCode`, `isNDC`, `ndcRedirectUrl`, `totalEmissionsKg`, `slices[].segments[].passengers[].baggages[]`. **What Bilt adds on top of Duffel:** - `totalPointsRequired` (Bilt Points cost at the fixed 1.25 cpp portal rate) - `isHafh` (Home Away From Home flag on hotels) - `loyaltyProgram.reference` (brand affiliation surfacing for hotels) - A few Bilt-specific filter fields **What this means for the toolkit:** - For **cash-only flight searches**, prefer the [duffel skill](../duffel/SKILL.md). It uses an authenticated Duffel API key, returns the same data faster,...
