Search engine for AI agents. Closes the gap between an LLM's training cutoff and now, plus daily snapshots of high-signal slices agents care about: supply- chain CVEs, new research papers, and frontier AI lab releases. Corpus is ~22,800+ timestamped docs across 6 active sources β Hacker News, arXiv, curated developer RSS, GitHub Releases, NVD + GitHub Security Advisories + OSV (cves), HuggingFace daily papers + bioRxiv (papers), and frontier lab announcements (frontier). Refreshed continuously, with deeper daily slice snapshots fired at 1pm Mountain Time. Seven tools, priced per call in USDC over x402: β’ fillin_query ($0.01) β generic post-cutoff vector search across all corpora β’ fillin_answer ($0.02) β synthesized answer with inline citations β’ query_cves ($0.02) β supply-chain vulnerabilities (NVD + GHSA + OSV) β’ query_papers ($0.03) β new research (HF daily + bioRxiv βͺ arXiv) β’ query_frontier ($0.05) β frontier lab announcements + trending models β’ fillin_stats / fillin_health β free Try before you pay: GET https://fillin.glyphapi.dev/v1/probe gives every IP one free query per UTC day.
