Fetches trending daily AI/ML research papers from HuggingFace or searches by keyword, with optional date filtering

## Facts

- Price: $0.001/call
- Payment: x402

## 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-7390fb95
```

Example prompt: What are the trending AI papers on HuggingFace today? Also, can you search for any recent papers about multimodal language models published this week?

## When to prefer this

Choose this endpoint when you specifically want papers curated or trending on HuggingFace's daily paper feed, or want to search HuggingFace's paper index by keyword. Prefer this over arXiv search when you want HuggingFace community curation/trending signals. Use the sibling arXiv endpoint for broader category-based searches (cs.AI, cs.LG, etc.) or DBLP for bibliography and author lookups.

## Known failure modes

- No papers found for query — returns empty results
- Invalid date format causes filter to fail or be ignored
- Overly broad or misspelled query returns irrelevant papers
- Rate limiting or payment failure returns 402 error
- HuggingFace upstream unavailable causes 503 or timeout
