# arXiv Paper Summarizer

> arXiv Paper Summarizer is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-16).

Fetches an arXiv paper's abstract via the arXiv API and generates a structured LLM summary including TLDR, key findings, methods, limitations, and so-what.

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 x402-deployer-x402-deployer-workers-dev-2e746bdf -d '<json body>'
```

Example prompt: Can you summarize arXiv paper 2310.06825 for me — give me the TLDR, key findings, methods used, limitations, and why it matters?

## When to prefer this

Use this endpoint when you need a structured, multi-section summary of a specific arXiv paper rather than just an abstract. Ideal for agents that need to quickly digest academic research and communicate findings in plain language. Prefer over manual abstract retrieval when you want LLM-generated insight layers like limitations and so-what analysis.

## Known failure modes

- Invalid or non-existent arXiv ID returns an error
- arXiv API unavailable causes fetch failure
- LLM generation failure returns partial or no summary
- Malformed request body missing paper ID returns 400
- Rate limiting or payment issues return 402 or 429

## How this service works

arXiv paper summarizer / research-paper TLDR. Fetches abstract via arXiv API + LLM-generated structured summary (TLDR, key findings, methods, limitations, so-what).

## Output

A structured JSON summary of the requested arXiv paper including: a TLDR (one-sentence summary), key findings (bullet points), methods description, limitations noted by the authors, and a so-what analysis explaining the paper's broader significance.
