## 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 gaspost-base-network-gas-conditions-beca9cc9
```

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

## When to prefer this

Choose this endpoint when you need real-time, uncached Base gas data read directly from a public node — ideal for transaction fee estimation, gas gating logic in DeFi bots, or chain health monitoring. Prefer this over third-party gas APIs when transparency and directness from the node (no intermediary cache) matter, and when EIP-1559 parameters (base fee + priority fee) are both needed simultaneously.

## Known failure modes

- Public node unavailability or timeout causing a 5xx error
- Network congestion on Base causing delayed or stale node responses
- Malformed response if the node returns unexpected data
- Rate limiting or payment failure (x402) preventing access

## How this service works

Current gas conditions on Base, read live from a public node: gas price, base fee of the latest block, suggested priority fee, latest block number and timestamp. No parameters. No third-party API, no cache.

## Output

A JSON object containing live Base network gas data: current gas price, base fee of the latest block, suggested priority fee (tip), latest block number, and latest block timestamp — all read directly from a public node at request time with no caching or third-party intermediaries.
