How to run a verified flight search that never books with Jev Ultrafast

Use the bundled Google Flights example to search a route, check the results and save a trace.

Short answer: Install the repo and keys as in Try it; then run uv run --env-file .env python examples/flights.py --keep-open; let it fill the form, wait for suggestions and run the search. All steps.

Who it is forA travel or ops developer prototyping fare search automation who must not trigger purchases.

The problemFlight sites are dynamic forms with comboboxes and date pickers that break naive automation.

The outcomeA completed search with the route, date and visible results checked independently, plus a saved trace, and no booking.

What you need first

  • Python with uv
  • Chrome with remote debugging allowed (connected through Browser Harness, installed by uv sync)
  • TYPESAFE_API_KEY and TEXT_MODEL_API_KEY (an OpenRouter key in the example config)
  • Live examples make paid API calls

Steps

  1. Install the repo and keys as in Try it
  2. Run uv run --env-file .env python examples/flights.py --keep-open
  3. Let it fill the form, wait for suggestions and run the search
  4. Read the check of route, date and results and inspect the saved trace
  5. Change the goal in the library example to your own route and date

Prompt for your agent

Using browser-use/jev-ultrafast, run examples/flights.py with --keep-open, then adapt the library example to search one-way flights from <city> to <city> on <date> for one adult in economy. Stop when results are visible and do not select or book anything.

Caveat. The README timing is three repeats of one task on one browser profile, not a general reliability benchmark.
