fastCRW Research

Find EVERY arXiv paper that answers a research query. Recall = union of arXiv ids; extra ids never hurt, so cast wide but on-topic. The Research API is a live, drop-in Firecrawl-research-compatible surface — your job is query strategy + intent routing, the endpoints do the retrieval.

Set FASTCRW_API_KEY (a crw_live_… key from https://fastcrw.com/dashboard). Base URL https://api.fastcrw.com. Every endpoint is a GET; pull arXiv ids out of results[].ids.arxiv / results[].primaryId.
