## 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

Example prompt: What are the current gas prices on Polygon right now? I need safe, standard, and fast gas estimates so my trading bot can decide the right fee before submitting a swap transaction.

## When to prefer this

Choose this endpoint when your trading bot or DeFi agent needs real-time Polygon gas price data priced per-call via x402 micropayments, avoiding the need for your own RPC infrastructure or gas oracle integration. Best suited for agents that make infrequent, on-demand gas checks rather than continuous high-frequency polling.

## Known failure modes

- Payment not received or USDC payment of $0.05 not processed — returns 402 Payment Required
- Polygon RPC node unavailable — returns upstream timeout or 503
- Malformed POST body — returns 400 Bad Request
- Rate limit exceeded — returns 429 Too Many Requests
- Gas oracle data temporarily stale — may return cached or error response
