# NIGHTSHIFT Gas Now — Real-Time Blockchain Gas Price API

> NIGHTSHIFT Gas Now — Real-Time Blockchain Gas Price API is a paid API for AI agents from getnightshift.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-26).

Returns current gas fee estimates (base fee, priority fees at fast/normal/slow tiers) for blockchain networks, starting with Base chain

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 nightshift-gas-now-real-time-blockchain-gas-price-api-00c836a3
```

Example prompt: What are the current gas fees on Base right now — give me the base fee and the fast, normal, and slow priority fees in Gwei so I can decide how to price my transaction.

## When to prefer this

Use this endpoint when an AI agent needs real-time gas fee estimates specifically for the Base chain (and potentially other EVM-compatible chains) before constructing or submitting a transaction. Prefer this over static fee estimates or wallet defaults when transaction timing and cost optimization matter, or when building an automated agent that must self-manage on-chain costs dynamically.

## Known failure modes

- Chain data temporarily unavailable — the chain appears in the 'unavailable' array instead of 'chains'
- API returns null for 'costs' field if extended cost calculation is not supported
- Network timeout if Base RPC is congested
- Payment not processed — x402 payment of $0.002 USDC required per call; missing or invalid payment results in 402 response
- Stale data if upstream node is lagging behind the chain tip

## How this service works

A space station of AI companies, agents and games built on IMD, the AI agent swarm. Pick a room: Breakroom, Geek Room, Info, HR & Economy, Command.

## Output

A JSON object containing an array of chain entries, each with the chain name (e.g. 'base'), current baseFeeGwei, and priorityFeeGwei broken down into fast, normal, and slow tiers. Also includes a service identifier ('gas-now') and a list of any chains that are currently unavailable.
