{"id":"dfa3197e-0933-40f3-a8cc-293a52f097ae","shortId":"UWfeHH","kind":"mpp","title":"Search tours and activities within a geographic bounding box via Amadeus, pay $0.05 per request.","tagline":"Search tours and activities within a geographic bounding box via Amadeus, pay $0.05 per request.","description":"This endpoint searches for tours, experiences, and activities within a geographic square defined by north/south/east/west latitude and longitude boundaries. It is part of StableTravel, a pay-per-request travel API suite that wraps Amadeus GDS data (flights, hotels, activities, transfers) and FlightAware AeroAPI (flight tracking, airport info, history). No API keys or subscriptions are required — payment via USDC on Base, Solana, or Tempo (x402/MPP protocol) serves as authentication.\n\nThe `/api/activities/by-square` endpoint accepts four required query parameters (`north`, `south`, `east`, `west`) defining the bounding box, plus an optional `max` parameter (default 50) to limit results. It returns an array of activity objects in JSON. The cost is $0.054 per call (listed as ~$0.05 in the docs). Data is sourced from Amadeus's Tours & Activities API.\n\nThis endpoint is one of three activity-related endpoints on StableTravel. Use `/api/activities/search` for radius-based searches around a lat/lng point, `/api/activities/by-square` for bounding-box searches (useful for map viewports), and `/api/activities/details` to retrieve full details for a specific activity by ID. The typical workflow is: search by area → get activity IDs → fetch details.","tags":["amadeus","flightaware","flights","hotels","activities","transfers","travel"],"capabilities":["activity-search","bounding-box-geo-query","amadeus-tours-activities","pay-per-request","no-auth-required","mpp-payment","x402-payment","usdc-settlement","json-api"],"categories":["geo","travel"],"synonyms":["tours search","things to do API","activities by bounding box","Amadeus activities","travel experiences search","sightseeing API","geographic square search","tours and activities"],"warnings":["Response schema items are untyped (empty `{}`) — actual response structure is inferred from Amadeus conventions, not documented in the OpenAPI spec.","No example response is provided in the OpenAPI spec for this endpoint."],"endpointUrl":"https://stabletravel.dev/api/activities/by-square","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stabletravel.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.880","qualityRationale":"Full OpenAPI 3.1 schema with parameter definitions, clear pricing ($0.054/call), live 402 MPP challenge captured, comprehensive guidance docs.
