# SuVerse Freight Offline Toll Estimator

> SuVerse Freight Offline Toll Estimator is a paid API for AI agents from api.suverse.io, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Estimates freight toll costs for a given truck route by accepting vehicle axle count, encoded polyline path, height, and maneuver data — offline, without live toll plaza connectivity.

## 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 suverse-freight-offline-toll-estimator-b1691390 -d '<json body>'
```

Example prompt: Estimate the toll costs for a 5-axle semi truck that's 13.5 feet tall along this encoded polyline route `_p~iF~ps|U_ulLnnqC_mqNvxq`@ — include any toll maneuvers at the major interchanges.

## When to prefer this

Use this endpoint when you need a quick, offline toll cost estimate for a freight truck route without needing live toll plaza API connectivity. Ideal for pre-dispatch budgeting, rate confirmation pricing, and carrier cost estimation workflows where vehicle-specific parameters (axles, height) are known and a route polyline is available. Prefer over live toll APIs when offline or batch estimation is acceptable and cost per call must remain low.

## Known failure modes

- Invalid or malformed polyline string returns a parsing error
- Unsupported axle count or out-of-range height value returns a validation error
- Empty or null toll_maneuvers array may produce incomplete estimates for complex interchanges
- Route polyline outside supported geographic coverage returns no toll data or an error
- Payment failure (x402) results in 402 response before any toll data is returned
