# Northline ChainKit Network Status

> Northline ChainKit Network Status is a paid API for AI agents from northline-chainkit.northline-c86.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Returns real-time network status and gas fee estimates for Base or Arc blockchain networks

## Facts

- Endpoint: GET https://northline-chainkit.northline-c86.workers.dev/v1/network/status?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/northline-chainkit-network-status-863f2d31
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_jB1_LbLSMyWUGmlmj5Li3

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 northline-chainkit-network-status-863f2d31
```

Example prompt: What's the current gas price and ERC-20 transfer fee estimate on the Base network right now?

## When to prefer this

Choose this endpoint when you need real-time gas price data and ERC-20 transfer fee estimates specifically for Base or Arc EVM-compatible chains, and you are operating in an x402 pay-per-call agent environment. Prefer this over general gas trackers when you need fee estimates denominated directly in USDC for programmatic decision-making.

## Known failure modes

- Invalid chain parameter (not 'base' or 'arc') returns a validation error
- Network unavailability on the queried chain may return stale or error response
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Worker timeout if the underlying RPC node is unresponsive

## How this service works

x402 pay-per-call onchain API (Base + Arc).

## Output

Returns a JSON object containing the queried chain name, current gas price in Gwei, and fee estimates for a standard ERC-20 transfer at 65k gas expressed in USDC, along with the fee unit label.
