Add Built Simple research API integration

[Built-Simple]

Integration: Built Simple

Built Simple provides free APIs for searching scientific literature with hybrid semantic + keyword search.

Components

This integration introduces 3 retrievers:

• BuiltSimplePubMedRetriever - Search 35M+ biomedical articles from PubMed
• BuiltSimpleArxivRetriever - Search preprints in physics, math, CS, and more
• BuiltSimpleCombinedRetriever - Search both sources simultaneously

Installation

pip install haystack-builtsimple

Links

• PyPI: https://pypi.org/project/haystack-builtsimple/
• GitHub: https://github.com/Built-Simple/haystack-builtsimple
• Documentation: https://github.com/Built-Simple/haystack-builtsimple#readme

Example

from haystack_builtsimple import BuiltSimplePubMedRetriever

retriever = BuiltSimplePubMedRetriever(top_k=5)
results = retriever.run(query="CRISPR gene therapy")
for doc in results["documents"]:
    print(f"[PMID {doc.meta['pmid']}] {doc.meta['title']}")

No API key required. Ready for use in Haystack 2.0+ pipelines.

@Built-Simple Thanks for contributing to Haystack integrations! Unfortunately, the linked GitHub repository is either private or does not exist. Although the examples look fine, I would love to have a look at the implementation as well.
