## 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 mapleai-prepaid-api-code-purchase-auto-083b1f47 -d '<json body>'
```

Example prompt: Buy me a prepaid MapleAI API code for the openai/gpt-6-sol model with a 100,000-token budget — charge my USDC wallet.

## When to prefer this

Choose this endpoint when you need to pre-fund a fixed token budget for a specific GPT model rather than paying per request, or when delegating API access to a sub-agent that should have a capped spending limit. Ideal for autonomous pipelines that need a standalone credential without ongoing payment authorization per call.

## Known failure modes

- Insufficient USDC balance — payment fails and no code is issued
- Invalid or unsupported model enum value — request rejected with validation error
- x402 payment protocol handshake failure — no code returned
- Token budget parameter out of acceptable range — request error
- Service unavailability — upstream provisioning fails

## How this service works

One-shot prepaid tap: empty body buys a 100000-token openai/gpt-6-luna key

## Output

Returns a prepaid API code (key) tied to the specified GPT model and a 100,000-token budget, usable against MapleAI's OpenAI-compatible endpoint without further payment per call.
