## 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-5-top-up-df3952de
```

Example prompt: Top up my YourAITools account with the $5 credit pack so I can start making calls to WebRead and InjectScan without paying per request each time.

## When to prefer this

Choose this endpoint when you need to make multiple calls to YourAITools APIs (PayGuard, WebRead, InjectScan, etc.) and want to avoid per-call on-chain x402 payments. The $5 pack is preferable to the $1 pack when you expect heavier usage, as it includes a 10% bonus (credited at $5.50). Prefer this over the $1 top-up when you have a batch of operations or want to minimize payment friction across a session.

## Known failure modes

- Payment failure — insufficient USDC or wallet connectivity issues result in no key being minted
- HTTP 400+ errors — malformed request or payment validation failure; no charge occurs
- Key loss — the returned API key is not re-issuable; if lost, credits may be inaccessible
- Service unavailability — if agentgate.workers.dev is down, the endpoint may be unreachable
- Price drift — individual route prices can change, so credited balance may cover fewer or more calls than expected

## 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 They are not money, not a token or investment, have no cash value, cannot be withdrawn and are not refundable; a failed call (HTTP 400 or higher) is not charged.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 confirming the top-up with fields: pack (e.g. '5'), topped_up (boolean true), balance_usd (total USD balance including bonus, e.g. '5.75'), and credited_usd (amount credited in this transaction, e.g. '5.50'). The minted API key is returned separately and should be stored as a Bearer token for subsequent calls to any paid YourAITools route.
