## 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 text-summarizer-by-pdfextractapi-863a08d3 -d '<json body>'
```

Example prompt: Can you summarize the following article in bullet points, keeping it under 150 words? [paste article text here]

## When to prefer this

Choose this endpoint when you need to condense long-form text into a user-specified format (brief, detailed, or bullet points) and optionally control the output length. It is well-suited for document processing pipelines, agent workflows that ingest large articles or reports, or any scenario where readable summaries of raw text are needed without requiring a full LLM orchestration layer.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Invalid style value (not 'brief', 'detailed', or 'bullets') — validation error
- Empty or missing 'text' field — 400 bad request
- max_words out of range (below 5 or above 2000) — validation failure
- Payment not provided or insufficient USDC — 402 payment required

## How this service works

Summarize text in a chosen style: brief, detailed, or bullet points.

## Output

Returns a summarized version of the input text in the requested style (brief, detailed, or bullet points), respecting the optional maximum word count.
