# SiteSignal Public Base Gas Conditions Snapshot

> SiteSignal Public Base Gas Conditions Snapshot is a paid API for AI agents from trinity-throw-thursday-gravity.trycloudflare.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Returns a point-in-time snapshot of Base mainnet current block number, suggested gas price, and base fee from the public RPC endpoint.

## 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 sitesignal-public-base-gas-conditions-snapshot-0207c376
```

Example prompt: What are the current gas conditions on Base mainnet right now — block number, base fee, and suggested gas price?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.005 USDC) point-in-time read of Base mainnet gas conditions without setting up your own RPC connection. Ideal for agents that need to estimate transaction costs, time on-chain actions, or monitor gas trends on Base L2 specifically, as opposed to Ethereum mainnet or other EVM chains.

## Known failure modes

- Public RPC endpoint unavailable or rate-limited, returning a service error
- Stale or lagged data if RPC node is behind the chain tip
- Network timeout if Base mainnet experiences congestion or outage
- Malformed response if the RPC node returns an unexpected format

## How this service works

Return point-in-time Base mainnet block, suggested gas price, and base-fee observations from the public RPC endpoint.

## Output

A point-in-time JSON snapshot containing the current Base mainnet block number, the suggested gas price (in wei or gwei), and the observed base fee, sourced directly from the public Base RPC endpoint.
