## 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 phantom-api-polygon-latest-block-4c430fef -d '<json body>'
```

Example prompt: What's the latest block on the Polygon network right now — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you need real-time Polygon block data via a pay-per-call model without committing to a subscription RPC provider. Ideal for lightweight agents or scripts that query block data infrequently and want to avoid API key management overhead. Prefer this over Alchemy or Infura when you need a simple x402 micropayment-compatible flow for Polygon specifically.

## Known failure modes

- Network or RPC node unavailability returns a 5xx error
- Payment failure or insufficient USDC balance results in a 402 response blocking the call
- Malformed request body returns a 400 validation error
- Transient Polygon node sync lag may return a slightly stale block

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns the latest Polygon block data including block number, block hash, parent hash, timestamp, miner address, gas used, gas limit, transaction count, and other standard block header fields from the Polygon network.
