# 47620 Polygon Block API

> 47620 Polygon Block API is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Returns the block header and summary for a Polygon blockchain block by number or 'latest', including hash, timestamp, transaction count, gas used, and base fee.

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-block-api-2c7a8410
```

Example prompt: What does the latest Polygon block look like — can you pull the hash, timestamp, transaction count, gas used, and base fee right now?

## When to prefer this

Use this endpoint when you need lightweight, fast Polygon block header data — hash, timestamp, tx count, gas used, and base fee — without fetching full transaction details. Ideal for monitoring, dashboards, or verification tasks on the Polygon network specifically. Prefer over full-node RPC calls when you want a simple pay-per-call HTTP API without running infrastructure.

## Known failure modes

- Invalid or non-existent block number returns an error or empty result
- Network issues fetching from Polygon RPC may cause timeouts
- Payment not processed (x402 protocol failure) results in 402 response
- Requesting a future block number returns not-found error
- Malformed 'fields' filter silently ignored or causes partial response

## How this service works

Header + summary for a polygon block by number (or "latest"): hash, timestamp, tx count, gas used and base fee.

## Output

Returns a JSON object with ok (boolean) and the block details including block hash, timestamp (unix), transaction count, gas used, and base fee per gas for the specified Polygon block number or 'latest'. Optional 'fields' query param can filter the response to specific top-level keys.
