## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability adh-tallinn-transit-live-feed-382017f5
```

Example prompt: Can you pull the live positions of all public transit vehicles running in Tallinn right now — I want to see which line, vehicle type, coordinates, and nearest stop for each one?

## When to prefer this

Choose this endpoint when you need a ready-to-use, pre-aggregated real-time snapshot of Tallinn's entire public transit vehicle fleet without having to integrate directly with Tallinn's raw GTFS-RT or MaaS APIs. It is ideal for agents that need location, line, and stop proximity in a single low-cost call ($0.01 USDC) via x402 micropayment, especially in agentic pipelines where direct API key management for each city's transit system is impractical.

## Known failure modes

- Upstream Tallinn transit API unavailable — returns error or stale data
- x402 payment not settled — request blocked before data is returned
- No vehicles active (off-hours) — count may be 0 with empty vehicles array
- Network timeout from source aggregator — delayed or missing response
- Malformed response if upstream feed format changes
