## 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-f6ad470b -d '<json body>'
```

Example prompt: Buy me a prepaid MapleAI API code for the gpt-6-luna model with 100,000 tokens so I can use it for LLM calls.

## When to prefer this

Use this endpoint when you need to pre-allocate a fixed token budget for a specific MapleAI GPT model before making LLM calls — ideal for cost-capping agent runs, isolating per-project spend, or distributing API access without sharing a master key. Prefer this over per-call billing when you want predictable spending or need to hand off a limited-use credential to a sub-agent.

## Known failure modes

- Invalid model enum value — returns validation error if model is not one of the four supported GPT identifiers
- Token count out of range or not a multiple of 100,000 — returns schema validation error
- Insufficient USDC balance or x402 payment failure — call is rejected with payment error
- Network or provider downtime — HTTP 5xx or timeout with no code issued

## How this service works

Buy a prepaid API code for one GPT model and a token budget

## Output

Returns a JSON object containing a unique prepaid code string, the selected model name, the API base URL (https://mapleai.shop/v1), a status URL for checking remaining tokens, and token counts (total and remaining). The code can then be used as an API key against the MapleAI OpenAI-compatible endpoint.
