# Myworker Agent API – Gas Fee Lookup (kadar-gas)

> Myworker Agent API – Gas Fee Lookup (kadar-gas) is a paid API for AI agents from crypto-micro-agent.mykira.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-20).

Returns current gas fees for Solana and/or EVM-compatible networks (Base, Ethereum, Arbitrum, Optimism), priced per call via x402 micropayment.

## Facts

- Endpoint: GET https://crypto-micro-agent.mykira.workers.dev/api/agent/kadar-gas?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-20

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_SVx-0-5UXDZui3PjALrl8

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 myworker-agent-api-gas-fee-lookup-kadar-gas-eb28b90a
```

Example prompt: What are the current gas fees on Base right now — give me the gwei price and an estimate of what a standard 21k gas transfer would cost in USD?

## When to prefer this

Choose this endpoint when you need real-time gas fee data for Solana and/or EVM-compatible chains (Base, Ethereum, Arbitrum, Optimism) in a single pay-per-call micropayment model without an API key subscription. It is especially useful for agents that need to compare fees across multiple chains before executing a transaction.

## Known failure modes

- Invalid network name returns an error or empty result
- Network RPC unavailable causes a 5xx or timeout
- Missing or rejected x402 payment results in 402 Payment Required
- Requesting an unsupported chain name returns no data for that chain

## How this service works

Servis berbayar untuk bot/agen (x402): data pasaran Solana via Jupiter + RPC, dan servis AI via Workers AI. Bayar per panggilan dengan USDC di Solana, USDC di Base, atau SOL.

## Output

Returns a JSON object with gas fee data per requested network: for Solana, base fee in lamports and median priority tip in microlamports; for EVM chains (Base, Ethereum, Arbitrum, Optimism), current gwei price and estimated USD cost for a 21,000 gas transfer.
