# Crypto Shark Bazaar – Chain Gas Price

> Crypto Shark Bazaar – Chain Gas Price is a paid API for AI agents from cryptoshark.duckdns.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Returns the current gas price on a supported blockchain network (e.g. Base), observed at a specific timestamp

## 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 crypto-shark-bazaar-chain-gas-price-abd4b428
```

Example prompt: What's the current gas price on the Base network right now?

## When to prefer this

Choose this endpoint when you need a cheap ($0.001 USDC), low-latency, on-demand gas price snapshot for the Base network or other supported chains within an autonomous agent workflow. Ideal for agents making cost-aware decisions before submitting on-chain transactions. Not ideal if you need historical gas price data or multi-chain aggregation at scale.

## Known failure modes

- Unsupported network identifier returns an error or empty result
- Stale data if the underlying oracle hasn't updated recently
- Rate limiting or payment failure (x402 micropayment not processed) returns 402
- Network connectivity issues to DuckDNS host may cause timeouts

## How this service works

Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents

## Output

A JSON object containing the blockchain network name (e.g. 'base'), the current gas price, and the timestamp at which it was observed (ISO 8601 format in observedAt).
