## 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 x402-payai-network-cbd95988 -d '<json body>'
```

Example prompt: Fetch the protected content at this URL using a USDC micropayment on Polygon mainnet — pay the required amount to the specified wallet address and return whatever resource is unlocked.

## When to prefer this

Choose this endpoint when you need to access paywalled content specifically on the Polygon (MATIC) mainnet using USDC via the x402 protocol. Use this over the Base sibling endpoint when the paywall is configured for Polygon. Ideal for micropayment-gated API resources, premium data feeds, or any x402-protected content requiring sub-cent USDC payments on Polygon.

## Known failure modes

- Insufficient USDC balance — payment cannot be completed
- Incorrect wallet address — payment sent to wrong destination
- Wrong payment amount — exact USDC amount not matched
- Polygon network congestion or transaction failure
- Invalid or expired payment authorization
- Content endpoint unreachable or removed
- Unsupported network — endpoint is Polygon-specific, not Base or other chains

## How this service works

Unlock protected content on Polygon mainnet by paying the exact USDC amount to the specified wallet; returns the requested resource.

## Output

The agent receives the unlocked protected resource content that was previously paywalled, returned after successful USDC payment verification on Polygon mainnet.
