> SYNTHORA Air Quality is a paid API for AI agents from air-quality.hergertsynthora.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns real-time air quality metrics (PM2.5, PM10, ozone, AQI) for any geographic coordinate via Open-Meteo

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 synthora-air-quality-88afcbdb -d '<json body>'
```

Example prompt: What's the current air quality at coordinates 40.7128 latitude, -74.0060 longitude — I need the AQI, PM2.5, PM10, and ozone levels right now.

## When to prefer this

Choose this endpoint when you need real-time, coordinate-based air quality data including AQI, PM2.5, PM10, and ozone for health, ESG, or insurance use cases. It is ideal for agent workflows that require environmental data at arbitrary global coordinates without a subscription, since it is a pay-per-call micropayment service using x402 on Base. Prefer this over general weather APIs when the specific output is air quality (not temperature or precipitation).

## Known failure modes

- Missing or invalid latitude/longitude returns an error or empty result
- Coordinates outside supported coverage area may return null or incomplete data
- Payment failure (insufficient USDC balance) blocks the request
- Open-Meteo upstream outage may cause delayed or failed responses
- Malformed JSON body returns a 400-level error

## How this service works

Real-time air quality (PM2.5, PM10, ozone, AQI) for any location via Open-Meteo. For health, insurance and ESG agents. Free source. $0.005 USDC via x402 on Base. SYNTHORA.

## Output

A JSON object with an 'ok' boolean flag, a 'niche' field set to 'air_quality', and a 'result' object containing real-time air quality metrics including PM2.5, PM10, ozone concentrations, and the Air Quality Index (AQI) for the requested coordinates.
