# ChainVerdict Base Gas Conditions

> ChainVerdict Base Gas Conditions is a paid API for AI agents from chainverdict.xyz, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns current Base network gas conditions — base fee and priority fee in gwei — at the latest block height, to help agents decide whether to transact now or wait.

## Facts

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 chainverdict-base-gas-conditions-81ac6d02
```

Example prompt: Before you send that USDC transfer, check what the current base fee and priority fee are on Base — I only want to proceed if gas is reasonable.

## When to prefer this

Choose this endpoint when your agent needs a quick, cheap ($0.002 USDC) real-time snapshot of Base network gas conditions before deciding to submit or defer a transaction. It is purpose-built for pre-transaction gas checks on Base and pairs naturally with other chainverdict.xyz endpoints for address screening and balance lookups. Prefer it over general blockchain explorers when you need a clean structured response without parsing HTML or managing RPC connections yourself.

## Known failure modes

- RPC node temporarily unavailable — may return a 5xx error or stale data
- Network congestion causing delayed block data
- Rate limit exceeded if called too frequently without payment
- Malformed response if upstream Base node is syncing

## How this service works

Base gas price oracle: current gas cost on Base, base fee and priority fee in gwei, at a stated block height. For agents deciding whether to transact now or wait.

## Output

Returns the current Base network base fee and priority fee, both expressed in gwei, along with the block height at which the reading was taken. Agents can use this to decide whether gas is low enough to proceed with a transaction or whether to wait for cheaper conditions.
