OpenClaw, meet
every airline. Paid per search.
Drop FlightAPI into your OpenClaw agent as a single tool call. Routes go in, ranked fares from 700+ airlines and OTAs come out, billed per search. No GDS contract, no API key wrangling, no monthly seat for your travel agent to forget about.
Real OpenClaw agents that rely on this tool.
Each pattern below is a single OpenClaw agent with FlightAPI registered as one tool. The math works because the agent only spends when it actually returns useful fares.
End-to-end trip plans from a one-line goal.
A user messages "book me to Tokyo in June, cheap." The OpenClaw agent runs round-trip and one-way searches, narrows by total cost and flight time, and presents top options. No human-managed GDS credentials anywhere in the chain.
Scheduled fare drops with zero idle cost.
A scheduled OpenClaw agent watches popular routes on cron. When fares drop below threshold, it pushes alerts via Slack or email. Days without a hit cost zero, so leaving a fleet of watchers running is cheap.
Benchmark every booked route.
Feed historical employee routes through the agent. OpenClaw queries FlightAPI for the same dates, surfaces where the booked fare was 20%+ above the lowest available, and produces a savings report — without paying a TMC for the same insight.
Auto-rebook when flights break.
An OpenClaw agent watches active flights. On delay or cancellation, it queries FlightAPI for alternates same calendar day, presents 3 options ranked by arrival time + price, and waits for human approval to book.
Stop wrapping GDS contracts into your agent.
Register one tool, connect a wallet, and your OpenClaw agent gets fares from 700+ airlines on every relevant call. Idle runs cost zero. Tool migrations later cost zero. That's the entire deal.

OpenClaw-specific questions.
If something below doesn't cover your case, ping us — we work directly with OpenClaw builders, no SDR funnel.
How does this register as an OpenClaw tool?
+
It's a single POST endpoint with a typed body. You register it in OpenClaw the same way you'd register any HTTP tool — endpoint, schema, price-per-call. OpenClaw uses the price to enforce budget caps and to show the user what each agent run will cost before it runs.
Does OpenClaw need a long-lived API key?
+
No. FlightAPI accepts x402-signed requests, so OpenClaw can pay per call from a wallet you connect. There's no shared secret to leak in agent logs or rotate every quarter.
What happens when an OpenClaw run hits its budget cap?
+
FlightAPI returns whatever it has resolved so far and OpenClaw stops the next call. The agent can decide whether to ask the user for more budget or hand off with the fares it has.
Can the agent book flights through this?
+
Not directly — this endpoint is read-only flight data (prices, status, schedules). For booking, your OpenClaw agent should hand off to your booking flow (carrier site, OTA, internal travel system). The API gives the agent the inputs; the human-approved action does the booking.
How is this different from giving OpenClaw an Amadeus seat?
+
Amadeus requires enterprise contracts and significant onboarding. The tool can't report a true per-call cost, so OpenClaw can't do real budget planning. FlightAPI reports an honest per-call cost up front, which is what OpenClaw was designed to consume.
Can OpenClaw call this concurrently across many agents?
+
Yes. Per-key rate limits apply with concurrency-fair queueing — a noisy agent never starves another agent on the same key.
