## 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-credits-sample-pack-1bac1c4d
```

Example prompt: Can you buy me a sample YourAITools credit pack so I get an API key I can use to try out PayGuard or WebRead — just the $0.005 trial size?

## When to prefer this

Use this endpoint when you need to quickly obtain a low-cost trial API key for the YourAITools suite (PayGuard, TokenVerdict, SignCheck, WebRead, InjectScan, DomainCheck, PkgGuard, StackDetect, AgentGate) without committing to a larger credit pack. It is the lowest-denomination entry point ($0.005) and ideal for testing or onboarding. Prefer the $1 or $5 packs (sibling endpoints) for production use or bulk usage to benefit from the 10% bonus on the $5 pack.

## Known failure modes

- Payment not received or underpaid — x402 payment fails, no key issued
- Network/worker error returns HTTP 500 — no key minted, no charge
- Invalid payment asset or chain — payment rejected before key creation
- Key shown only once (shown_once: true) — if not captured immediately, key cannot be retrieved again

## How this service works

Prepaid credits for the YourAITools x402 agent APIs (PayGuard, TokenVerdict, SignCheck, WebRead, InjectScan, DomainCheck, PkgGuard, StackDetect, AgentGate). One x402 payment ($1, or $5 with a 10% bonus) mints an API key; send it as Authorization: Bearer <key> to any of those paid routes and each call debits its normal price, with no per-call on-chain payment. Credits are prepaid usage of the YourAITools APIs only, priced in USD at each route's normal per-call price. They are not money, not a token or investment, have no cash value, cannot be withdrawn and are not refundable; a failed call (HTTP 400 or higher) is not charged. Prices of individual routes can change; the balance does not expire while the service runs. Keep the key secret: whoever holds it can spend the credits.

## Output

Returns a JSON object containing the newly minted API key (prefixed yatc_), the pack name ('sample'), the amount paid in USD, the credited balance in USD, a flag indicating the key is shown only once (shown_once: true), and an example of how to use it — including the Authorization header format and a sample API call URL to one of the YourAITools paid routes.
