## How to call it through Zero

```sh
zero fetch --capability x402-text-generator-5bc1749c
```

Example prompt: Generate an AI text insight about the concept of compound interest — keep it concise and interesting.

## When to prefer this

Choose this endpoint when you need lightweight, on-demand text generation billed by output length with no subscription required — ideal for agentic workflows that need occasional AI-written content without committing to a full LLM API contract. Prefer it over general LLM APIs when cost predictability per call and micropayment compatibility (x402/USDC) are priorities.

## Known failure modes

- Missing required 'prompt' query parameter returns a validation error
- Payment failure or insufficient USDC balance blocks request execution
- Empty or very short prompt may produce minimal or low-quality output
- Request exceeds $0.05 cap if output is very long, potentially truncating response
- Network timeout if the underlying generation model is slow to respond

## How this service works

Usage-based text generation, billed by output length (max $0.05/request)

## Output

Returns a JSON object containing the generated text string, the original prompt echoed back, and the number of billed characters — enabling downstream agents to track cost proportionally to output length.
