# base-network-info

> base-network-info is a paid API for AI agents from x402.agentindex.world, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Returns Base mainnet network info in a single call: chain ID, current block height, and gas price in both wei and gwei.

## Facts

- Endpoint: GET https://x402.agentindex.world/base/network-info?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

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 base-network-info-5ee0a4c5
```

Example prompt: What's the current gas price on Base mainnet right now, and what block are we at?

## When to prefer this

Choose this endpoint when you need a quick, single-call snapshot of Base mainnet state — chain ID, block height, and gas price — without setting up your own RPC node or paying for a dedicated provider subscription. Ideal for agents that need to make gas estimates, verify network identity, or decide whether conditions are right to submit a transaction, at a low per-call cost of $0.001 USDC.

## Known failure modes

- RPC node unavailable — upstream Base node may be unreachable, returning a 5xx error
- Stale data — if the underlying node is syncing, block_number may lag behind tip
- Payment failure — x402 payment of $0.001 USDC not processed correctly, returns 402
- Rate limiting — too many requests in a short window may result in 429 or payment rejection

## How this service works

Base mainnet network info in one call: chain ID, block height, and current gas price (wei and gwei).

## Output

A JSON object with four fields: chain_id (integer, Base mainnet chain ID = 8453), block_number (integer, current block height), gas_price_wei (integer, current gas price in wei), and gas_price_gwei (float, current gas price in gwei). All values reflect the live state of the Base mainnet at the time of the call.
