# StatePulse Pollen Telemetry

> StatePulse Pollen Telemetry is a paid API for AI agents from statepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns live pollen levels (birch, grass, ragweed) and overall allergy risk level for a given location

## Facts

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 statepulse-pollen-telemetry-59228d71 -d '<json body>'
```

Example prompt: What are the live pollen levels in Austin, Texas right now — birch, grass, and ragweed — and how bad is the overall allergy risk?

## When to prefer this

Use this endpoint when an agent needs real-time, per-species pollen breakdown (birch, grass, ragweed) with an explicit risk classification and confidence score — especially in agentic health, outdoor planning, or allergy-awareness contexts that require pay-per-call, keyless access via x402 USDC on Base.

## Known failure modes

- Location not supported — 'supported: false' returned with no pollen data
- Low confidence result when data sources are sparse for the region
- Invalid or missing location parameter returns an error
- Payment failure via x402 if USDC balance is insufficient

## How this service works

Queries pollen allergen index counts (grass, birch, oak) by coordinate using Open-Meteo.

## Output

A JSON object with the overall allergy risk level (e.g. low/medium/high), individual pollen counts for birch, grass, and ragweed (numeric), a confidence rating for the data, and a boolean indicating whether the queried location is supported.
