## How to call it through Zero

```sh
zero fetch --capability cheaptokens-ai-3ea0877f -d '<json body>'
```

Example prompt: Buy me $2 worth of Venice.ai API credits via cheaptokens.ai for today — I want the discounted key so I can use Claude and Llama models through the OpenAI-compatible endpoint.

## When to prefer this

Choose this endpoint when an agent needs OpenAI-compatible AI inference at reduced cost and can pay in USDC, especially for same-day or pre-reserved future date usage; ideal for cost-sensitive agentic workflows needing access to diverse models including uncensored variants not available on mainstream APIs.

## Known failure modes

- Payment below $0.50 minimum rejected with validation error
- Invalid or malformed date format returns schema error
- Expired paymentSessionId requires fresh 402 flow
- Credits expire at 23:59 UTC same day if date not specified
- USDC payment failure or insufficient balance blocks key issuance

## How this service works

OpenAI-compatible LLM inference and chat completions via discounted Venice API credits. Pay USDC to receive a live Venice.ai API key for /api/v1 models, chat, images, audio, video, and embeddings. Same-Day credits are 30–90% below Venice direct and expire at 23:59 UTC; Prepaid API Keys support recurring agent jobs.

## Output

Returns a live Venice.ai API key loaded with credits proportional to the USD paid, valid until 23:59 UTC on the specified or current date; the key works with Venice's standard /api/v1 endpoints and all supported models.
