## 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 fastapi-online-bio-generator-bf7bdfdc -d '<json body>'
```

Example prompt: Using my facts — 'Sarah Chen, software engineer with 10 years at Google, Stanford CS grad, open-source contributor, based in San Francisco, loves hiking and coffee' — write me a professional bio of about 80 words.

## When to prefer this

Choose this endpoint when you need a quick, affordable, no-signup bio generation from structured facts with per-call crypto pricing. It is especially useful for agents automating profile creation workflows or content pipelines where OpenAI or similar platforms are too expensive or require account setup.

## Known failure modes

- Empty or too-short facts string may produce generic or low-quality output
- Requested length outside 10–500 word range will be rejected with a validation error
- Facts exceeding 4000 characters will be rejected
- Network timeouts if inference model is under load
- Crypto payment failure if wallet balance is insufficient
