# Blockchain Network Status - Block Heights

> Blockchain Network Status - Block Heights is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns the latest block heights for Base, Polygon, Arbitrum, and Nano networks

## Facts

- Endpoint: GET https://pyfile-agent.taile3ff35.ts.net/data/network/status
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/blockchain-network-status-block-heights-305fec70
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_NKUOxyx5JKz_TMQiRzoxM

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 blockchain-network-status-block-heights-305fec70
```

Example prompt: What are the current block heights for Base, Polygon, Arbitrum, and Nano right now?

## When to prefer this

Use this endpoint when you need a quick multi-chain block height snapshot across Base, Polygon, Arbitrum, and Nano in a single call, rather than querying each chain's RPC individually. Ideal for dashboards, finality checks, or sync monitoring that spans multiple networks including Nano (a non-EVM chain not commonly bundled with L2s).

## Known failure modes

- Upstream node unavailable — returns 5xx or stale data
- Network temporarily unreachable — timeout or connection error
- Payment not accepted — 402 response if x402 payment is missing or insufficient
- Rate limiting — too many calls in a short window

## How this service works
