## 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 fast-token-api-key-purchase-6d8edc65 -d '<json body>'
```

Example prompt: Buy me a Fast Token prepaid API key with $5 of credits and label it 'my-agent-project' so I can use it with OpenAI-compatible chat completions.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically acquire a prepaid API key for OpenAI-compatible inference (chat completions, embeddings) and wants to pay using USDC via the x402 protocol rather than managing a subscription or monthly billing account. Ideal for pay-as-you-go or ephemeral agent workflows that need immediate, credit-limited AI API access.

## Known failure modes

- Payment below minimum $0.10 or above $1000 USD — rejected with validation error
- x402 payment not confirmed on-chain — purchase not fulfilled
- Invalid or missing amount_usd — schema validation error
- Network or gateway timeout during key provisioning
- Duplicate purchase attempts may return reused:true with existing key

## How this service works

Fast Token is an x402-powered prepaid API key gateway for OpenAI-compatible Azure inference endpoints.

## Output

Returns a JSON object containing a live bearer API key (sk_live_...), key_id, credits added and remaining, whether the key was reused, expiry info, and a full map of available gateway endpoint paths (chat completions, embeddings, models, balance, etc.). The key can immediately be used as Authorization: Bearer <api_key> against the gateway.
