agent travel API / AI travel planner API

Use AICO before live provider fanout when an autonomous travel agent needs constraint-safe destination search, live_places evidence where available, plan validation, and provider-ready handoffs in stable JSON.

Activation path: POST /api/v1/activation → travel.intent.parse → travel.destinations.search → travel.places.search → travel.plan.validate → travel.provider_handoffs.generate. Matched first-value responses expose commercial_next_step; API-key agents can record POST /api/v1/commercial/intent before browser-authenticated billing, and POST /api/v1/api-requests captures missing primitives under agent_requested_api.

Paid path: Hobby: $5 minimum usage/month with $5 credits included; pricing_model: "usage_token_minimum"; commercial_next_step.requires_browser_billing_account: true until a safe billing bridge exists.

Travel truth boundaries: live_booking_inventory: false, provider_backed_rates: false, live_flight_fares: false until a live provider verifies booking inventory, rates, taxes/fees, and fares; provider validation remains required for booking decisions.

used goods deal validation API

Use AICO when an agent has a marketplace listing or buying intent and needs normalized eBay provider evidence or authorized Craigslist snapshots, comparable-price context, risk checks, and seller handoff questions without re-scraping pages.

Marketplace truth boundaries: availability_guaranteed: false, seller_identity_verified_by_aico: false, aico_checkout_supported: false, aico_escrow_supported: false.

agent skill search API

Use AICO when a coding or operating agent needs branchable procedure options from skill libraries before deciding which instructions to inspect or execute.

Skill truth boundaries: executes_skill: false, installs_dependencies: false, guarantees_best_option: false, live_web_search: false.
