## 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 agent-paywire-credits-purchase-1d5213c8 -d '<json body>'
```

Example prompt: Buy me 100 calls on Agent Paywire so I can start researching stablecoin and machine-to-machine payment protocols for AI agents.

## When to prefer this

Use this endpoint when you need prepaid access to Agent Paywire's AI payment intelligence content and want to pay once via USDC stablecoin rather than per-call. Prefer the 1000-call bundle for production or high-frequency agent workloads (better unit economics at 0.007 USDC/call vs 0.008 USDC/call). Choose the 100-call bundle for evaluation or low-volume use. This is the correct endpoint when you need to establish or replenish a credit balance before making content queries on the platform.

## Known failure modes

- Insufficient USDC balance — payment rejected, no credits issued
- Invalid 'calls' value not in enum [100, 1000] — returns 400 validation error
- Payment protocol (x402) handshake failure — transaction not completed
- Expired or invalid payment authorization — credits not granted
- Service unavailable — 5xx error with no credit bundle created
