## 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-pack-1-863a3c3b
```

Example prompt: Buy me the $1 YourAITools credit pack so I get an API key to query the AI tools directory — pay with USDC on Base.

## When to prefer this

Use this endpoint when an agent needs to obtain a fresh API key and $1.00 credit balance for the YourAITools directory APIs, specifically when paying via USDC on Base or Solana through the x402 protocol. Prefer this over manual key generation workflows when operating in a crypto-native, agentic context where programmatic payment and credential minting is required in one step.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not confirmed — no API key issued
- Invalid pack ID: requesting a non-existent pack number returns an error
- Network timeout: slow blockchain confirmation causes request to hang
- Duplicate payment: attempting to repurchase may result in a new key rather than topping up existing key
- shown_once flag: API key is only shown once in the response; losing it requires purchasing a new pack

## How this service works

Prepaid API credits ($1 pack). Prepaid credits for the YourAITools agent APIs: one x402 payment of $1 USDC mints an API key holding $1.00 of credits. 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 minted API key (api_key), authorization header string for use in subsequent requests, current balance_usd ($1.00), credited_usd, paid_usd, the pack identifier, and a shown_once flag indicating this is a one-time display of the key.
