## 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 youraitools-credit-pack-purchase-5-960a24b1
```

Example prompt: Buy me the $5 credit pack on YourAITools so I can get an API key to access their directory of AI tools that accept crypto payments.

## When to prefer this

Use this endpoint when you need to obtain an API key and credit balance specifically for the YourAITools platform, which provides a curated directory of AI tools and agents accepting USDC payments via x402 on Base or Solana. Choose this over other credit pack tiers (e.g. $1, $10, $25) when $5 of credit is the right amount for your usage. This is the entry point for any agent that needs to authenticate with YourAITools APIs downstream.

## Known failure modes

- Payment failure or insufficient USDC balance — x402 payment not processed
- Network timeout during payment settlement
- Invalid or missing x402 payment header — returns 402 Payment Required
- Pack tier not found or unavailable
- API key generation failure on server side

## How this service works

Prepaid API credits ($5 pack with bonus). Prepaid credits for the YourAITools agent APIs: one x402 payment of $5 USDC mints an API key holding $5.50 of credits ($0.50 bonus). Send it as Authorization: Bearer <key> to PayGuard, TokenVerdict, SignCheck, WebRead, InjectScan, DomainCheck, PkgGuard, StackDetect or AgentGate paid routes; each call debits its normal price instead of an on-chain payment. Key shown once. Prepaid API usage only, not refundable.

## Output

Returns a JSON object containing: the purchased pack tier, a new API key (bearer token), the amount paid in USD, the total credited USD balance, a flag indicating the key is shown only once, and an example of how to use the key as an Authorization header.
