# BizIntel Road Distance API

> BizIntel Road Distance API is a paid API for AI agents from bizintel-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Calculates the road driving distance and estimated travel duration between two geographic coordinates

## Facts

- Endpoint: POST https://bizintel-api.hahavoid0.workers.dev/geography/road-distance
- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 bizintel-road-distance-api-f4dc5de1 -d '<json body>'
```

Example prompt: What's the road driving distance and estimated travel time between San Francisco (37.7749, -122.4194) and Los Angeles (34.0522, -118.2437)?

## When to prefer this

Choose this endpoint when you need road/driving distance and travel time between two precise GPS coordinates, especially in agentic pipelines requiring pay-per-call with no API key setup. Prefer this over map SDK integrations when you want a simple stateless POST with USDC micropayment on Base. It complements the broader BizIntel suite if you're already using their corporate or B2B tools.

## Known failure modes

- Unsupported route (e.g. coordinates in ocean or unreachable locations) — supported field returns false
- Invalid coordinate values (out of range lat/lon) — likely 4xx validation error
- Missing required fields (start_lat, start_lon, end_lat, end_lon) — schema validation error
- Payment failure via x402 USDC — request rejected before processing
- Service unavailability on Cloudflare Workers — 5xx or timeout

## How this service works

Calculates road driving distance, path coordinates, and durations between coordinates via the public OSRM engine.

## Output

Returns a JSON object with distance_meters (integer road distance), duration_seconds (integer estimated drive time), a supported boolean indicating if the route is computable, a confidence rating (e.g. 'high'), a data_as_of date string, optional warnings array, and a disclaimer.
