How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
A JSON object containing the query string used, and an array of datasets each with a type (e.g. 'public-transit'), a list of feeds with their URLs and formats (e.g. GTFS), and a title for the dataset — enabling downstream transit data ingestion or route planning.
Example use cases
GTFS feed lookup for trip planning
“I'm building a transit app and need the GTFS feed URLs for public transport in Martinique — can you fetch those for me?”
Regional transport data for data pipeline
“Can you get me the public transit datasets and feed links for Île-de-France so I can ingest them into our transport analytics pipeline?”
Checking transit availability for a French city
“Does Lyon have publicly available GTFS transit feeds? Can you look that up and give me the download URLs?”
Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/transportWhen to prefer
Choose this endpoint when you need to programmatically discover GTFS public transit feed URLs for French regions, departments, or overseas territories without needing an account or API key — particularly useful in agent workflows requiring pay-per-call micropayment access via the x402/USDC protocol. Prefer this over manual web searches or static datasets when you need structured, machine-readable transit feed discovery at low cost.
Side effects
- No datasets found for the queried region — empty datasets array returned
- Invalid or missing 'input' object results in schema validation error
- Payment failure via x402 protocol if USDC balance is insufficient
- Region name misspelled or not recognized — returns empty or irrelevant results
- Service unavailability on Vercel hosting causing 5xx errors
