How this service works
Munition gives AI agents one MCP wrapper for small paid services with anonymous accounts, x402 settlement, and no API-key friction.
Output
Returns a JSON object containing the offer ID, cabin class, total price in USD, itinerary with flight segments (departure/arrival airports and times, carrier code, flight number, number of stops), fare conditions (changeable/refundable flags), baggage allowance (carry-on and checked), validating airline codes, and a timestamp of when the offer was searched.
Example use cases
Example prompt
“Can you pull up the full details for Duffel flight offer off_0000A3bQ8FJj5aa6HYwq0Q — I want to see the price, itinerary segments, and whether it's refundable before I book it?”
Technical details
Endpoint
GEThttps://api.munition.io/v1/flights/offers/%7Bid%7DWhen to prefer
Use this endpoint when you already have a Duffel offer ID from a prior flight search and need to retrieve the full offer details — pricing, segments, baggage, and fare conditions — before presenting options to a user or proceeding to booking. Prefer this over a full search when you want to refresh or confirm a specific known offer. Ideal for agents that need anonymous, no-API-key access to flight data paid per-call via x402.
Side effects
- Invalid or expired offer ID returns an error — Duffel offers are time-limited and may become stale
- Malformed offer ID (not matching Duffel format like off_...) returns a 400 validation error
- Offer no longer available (sold out or expired) returns a 404 or similar not-found response
- Payment failure via x402 (insufficient USDC balance) prevents the call from completing
- Network timeout if Duffel upstream is slow to respond
