## 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 agentdata-api-gas-prices-base-mainnet-fd95dd00
```

Example prompt: What are the current slow, standard, and fast gas prices in gwei on Ethereum right now? Pay via USDC micropayment if needed.

## When to prefer this

Choose this endpoint when an AI agent needs real-time gas price estimates for blockchain transaction cost planning, DeFi operations, or smart contract interactions, and can pay $0.001 USDC per call via x402 without requiring an API key or account setup.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported network identifier — returns 400 Bad Request
- Network data temporarily unavailable — returns 503 Service Unavailable
- Malformed request body — returns 400 with validation error

## How this service works

Pay-per-request crypto market data API for AI agents. 16 endpoints on Base Mainnet via x402 protocol. No accounts, no API keys. USDC micropayments from $0.001. Works with Claude Desktop, ElizaOS, and any MCP client.

## Output

Returns current gas price estimates (slow, standard, fast) in gwei or equivalent units for the requested blockchain network, along with a timestamp of when the data was fetched.
