# ClimatePulse Air Quality Index

> ClimatePulse Air Quality Index is a paid API for AI agents from climatepulse-six.vercel.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns the current Air Quality Index (AQI) for a given location along with health guidance and recommended protective measures for outdoor activity.

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 climatepulse-air-quality-index-3c0875ee
```

Example prompt: What's the current air quality index in Denver, Colorado, and is it safe to go for a long outdoor run or should I take precautions?

## When to prefer this

Choose this endpoint when you need current AQI data paired with actionable health guidance and protective measure recommendations — not just raw pollution numbers. Ideal for health-focused agents, outdoor activity planners, or scenarios involving sensitive populations (children, elderly, respiratory conditions). Prefer over a generic weather endpoint when air quality specifically drives the decision. For wildfire smoke specifically, a sibling smoke-tracker endpoint may be more appropriate.

## Known failure modes

- Location not found or ambiguous — returns error indicating unresolvable location
- Air quality data unavailable for the requested region — returns data gap error
- Invalid coordinates or malformed location parameter — returns 400-level validation error
- Service unavailable or upstream data source down — returns 5xx error
- Payment not processed — returns 402 Payment Required

## How this service works
