# 47620 Polygon Data API – Chain Snapshot

> 47620 Polygon Data API – Chain Snapshot is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Returns a single consolidated snapshot of Polygon network state including chain ID, latest block, gas price, native POL/USD price, and canonical USDC address.

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-data-api-chain-snapshot-67d40dff
```

Example prompt: Give me a full Polygon network snapshot — chain ID, latest block, current gas price, POL/USD price, and the canonical USDC address — all in one shot.

## When to prefer this

Use this endpoint when you need multiple Polygon network data points (chain ID, block, gas, price, USDC address) simultaneously and want to avoid making several separate RPC or price-feed calls. Ideal for agents that need a quick pre-flight check before submitting Polygon transactions, or for dashboards that display live Polygon network state. Prefer over individual RPC calls when cost of multiple round-trips exceeds $0.01 USDC per consolidated snapshot.

## Known failure modes

- Upstream RPC or price feed unavailability may cause 5xx errors or stale data
- Malformed 'fields' query parameter may return unexpected subset or error
- Rate limiting or payment issues (x402) may result in 402 Payment Required responses
- Network congestion may cause slight delays in block/gas data freshness

## How this service works

One call for the whole polygon picture: chain id, latest block, gas price, native token POL/USD price and the canonical USDC address. Replaces several separate calls.

## Output

A JSON object containing: a boolean 'ok' status, the endpoint identifier, Polygon chain ID, the latest block number, current gas price (in gwei or wei), POL/USD spot price, and the canonical USDC token contract address on Polygon — all from a single GET request.
