# arXiv AI/ML Paper Search

> arXiv AI/ML Paper Search is a paid API for AI agents from ai.memoryapi.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Searches recent arXiv submissions by keyword and category across AI, ML, NLP, CV, robotics, and statistics domains

## Facts

- Endpoint: GET https://ai.memoryapi.org/x402/ai/arxiv
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ai-memoryapi-org-bdd97569
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_fMTUNMkAFF2DArOwW8cjc

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 ai-memoryapi-org-bdd97569
```

Example prompt: Search arXiv for recent cs.LG papers on reinforcement learning from human feedback — show me the latest submissions.

## When to prefer this

Use this endpoint when you need to search recent arXiv submissions specifically in AI/ML subfields (cs.AI, cs.LG, cs.CL, cs.CV, cs.RO, stat.ML). Prefer this over the HuggingFace sibling endpoint when you need arXiv-native metadata and broader category coverage, or over DBLP when you want recent preprints rather than published/peer-reviewed bibliography data.

## Known failure modes

- No results found for the given keyword/category combination
- Invalid category code returns an error or empty result
- Payment not processed (x402 payment required, returns 402 if unpaid)
- Rate limiting or service unavailability returns 5xx error
- Very broad queries may return too many results with limited filtering

## How this service works

x402 micropayment-gated API for AI/ML research papers. Access trending HuggingFace papers, arXiv submissions, and DBLP bibliography search. Pay $0.001 USDC per request on Base.

## Output

Returns a list of recent arXiv papers matching the keyword and category filter, including paper titles, abstracts, author lists, arXiv IDs, submission dates, and categories.
