# 47620 Polygon Network Health API

> 47620 Polygon Network Health API is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Returns live Polygon network health data including chain ID, latest block number, current gas price, and POL/USD token price in a single call.

## 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 47620-polygon-network-health-api-fcef6302
```

Example prompt: What's the current Polygon network status? I need the latest gas price and POL/USD price before I send a transaction.

## When to prefer this

Choose this endpoint when you need a fast, cheap single-call snapshot of Polygon network conditions — specifically gas price, block height, chain ID, and POL/USD price — without querying multiple RPC endpoints yourself. Ideal for agents that need to price a Polygon transaction, verify network liveness, or enrich on-chain data with the current token price. Prefer over raw RPC calls when you want a normalized JSON response with price data bundled in at minimal cost ($0.002/call).

## Known failure modes

- Polygon RPC node temporarily unavailable — health check may return ok:false or an error response
- Price feed delay if upstream oracle is slow — POL/USD may be slightly stale
- Invalid 'fields' parameter values silently ignored or returning empty subset
- Payment failure (x402) if USDC balance is insufficient — request rejected before data is returned
- Network timeout if Polygon RPC is congested

## How this service works

Live polygon network health: chain id, latest block number, gas price and native token POL/USD price. Cheapest call.

## Output

A JSON object containing a boolean health status flag, the Polygon chain ID, the latest block number, current gas price (in wei or gwei), and the native POL token price in USD, plus the endpoint identifier. Optionally filtered to specific top-level keys if the 'fields' query parameter is used.
