npm package inspection API: latest version, publish date, license, deprecation status, dependency count, and maintainer count for any npm package. Dependency hygiene for coding agents, cached hourly.

Mole-to-mass-to-molecule-count converter for any chemical formula: supply a mass in grams or an amount in moles and get the full conversion set computed from the compound's exact molar mass. Useful for lab calculations, dosage prep, and chemistry education tools.

Full Bible chapter by book and chapter number — e.g. Psalm 23, Romans 8 — served from a locally hosted, complete King James Version (KJV) text: all 66 books, 1,189 chapters, no third-party dependency at request time. Book names are matched case-insensitively and understand common abbreviations. Returns every verse in the chapter individually and as continuous reading text. Unknown books or out-of-range chapter numbers return a clean validation error, never a crash.

Remote file hashing API: SHA-256/512/SHA-1/MD5 checksum of any file URL up to 50MB — verify downloads, releases, and models against published checksums before trusting them. Supply-chain hygiene for agents.

File checksum API: fetch any public file URL (up to 50MB) and return its SHA-256/SHA-512/SHA-1/MD5 hex digest — verify a download matches its published checksum BEFORE trusting it. Supply-chain safety for agents installing packages, models, and binaries. File is hashed in memory and discarded.

Word association API: synonyms, rhymes, similar-sounding words, or strongly-associated terms for any word, ranked by strength. For copywriting, naming, poetry, and word-game agents.
