## When to prefer this

Choose this endpoint when you need current natural gas market pricing data delivered through an MCP-compatible, pay-per-call API pattern. Particularly useful for agents that need energy commodity data without a subscription, paying only $0.02 USDC per call via x402 protocol. Best when you need lightweight, on-demand gas price lookups rather than a full commodity data subscription.

## Known failure modes

- Payment failure (insufficient USDC balance) resulting in 402 error
- Rate limiting if too many requests are made in quick succession
- Service unavailability on the Cloudflare Workers edge endpoint
- Malformed request body resulting in 400 error
- No data available for requested gas market segment

## How this service works

## Output
