How this service works
Searches a locally harvested metadata-only index of public scientific assets from free/open APIs. Returns curated pointers, licenses, provenance, freshness hashes, and source metadata without downloading or reselling the underlying open datasets, model weights, papers, or repositories.
Output
Returns curated metadata pointers to matching public scientific assets, including their source URLs, license types, provenance records, freshness/content hashes, and source metadata — without downloading or transferring the underlying datasets, weights, papers, or code.
Example use cases
License-safe ML dataset discovery
“Find me open scientific datasets about protein folding that have permissive licenses like MIT or Apache — I just need the metadata pointers and license details, not the actual data files.”
Provenance check for research reproducibility
“Search the open science metadata index for model weights related to natural language processing published in the last year, and give me their provenance records and freshness hashes so I can verify reproducibility.”
Open repository discovery by topic
“I'm looking for publicly available scientific repositories on climate change — can you search the Polymathica metadata index and return source metadata and curated pointers for the top results?”
Technical details
Endpoint
POSThttps://api.macaroonnetwork.com/execute/polymathica-open-science-metadata-search-v1When to prefer
Choose this endpoint when you need to discover and evaluate public scientific assets (datasets, models, papers, repos) by their metadata, license, and provenance before committing to download — especially when license compliance verification or provenance tracking is important. Prefer over general web search when you need structured, curated open-science metadata with freshness hashes. Use the graph-view or license-compliance sibling endpoints if you need relationship traversal or deeper license analysis.
Side effects
- Query yields no matching assets in the locally harvested index
- Asset metadata is stale if source has been updated since last harvest
- License field may be missing or incomplete for some assets
- Schema validation error if required body fields are malformed
- Payment failure (402) if USDC balance is insufficient
