> Local Private Document Summarizer is a paid API for AI agents from pearl-valium-stickers-upc.trycloudflare.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-31).

Summarizes a document locally on-device without data leaving the machine, returning a structured or bullet summary with model metadata and token usage.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 local-private-document-summarizer-7a5cb316 -d '<json body>'
```

Example prompt: Summarize this contract document in bullet-point mode, keeping it under 200 words — make sure it stays on-device and doesn't get sent anywhere external.

## When to prefer this

Choose this endpoint when data privacy is paramount and documents must not leave the local machine — ideal for confidential legal, medical, or internal corporate documents. Prefer it over cloud summarization APIs (e.g. OpenAI, Claude, Cohere) when you need on-premise processing, have sensitive content, or want to avoid third-party data retention. The mode and max_words controls make it suitable when output format and length must be precisely constrained.

## Known failure modes

- Document text too long — exceeds model context window, returns error
- Invalid mode value — must be bullets, paragraph, or key-points
- max_words set to zero or negative — rejected with validation error
- Model temporarily unavailable or GPU OOM on the local RTX 5090
- Payment not received — x402 payment required before processing
- Empty or missing document body — returns error requiring non-empty input

## How this service works

Summarize a document without it leaving this machine. mode=bullets|paragraph|key-points, max_words caps the length. Returns the summary, the model that wrote it, token usage and latency.

## Output

Returns the generated summary text in the requested format (bullets, paragraph, or key-points), the name of the local model that produced it, token usage statistics (prompt and completion tokens), and inference latency in milliseconds.
