Build with UCFP.

Guides, references, and recipes for every modality. Pick a starting point — most teams begin with Getting started.

• 01

  Getting started

  Install UCFP, send your first fingerprint, and learn the proxy contract behind /api/fingerprint.

• 02

  Authentication

  Bearer tokens, the X-Api-Key fallback, and how to rotate keys safely.

  →
• 03

  API reference — text

  Every text fingerprinting algorithm UCFP exposes — MinHash, SimHash, LSH, TLSH, semantic embeddings — with full parameter coverage.

  →
• 04

  API reference — image

  Image fingerprinting — multi-hash, perceptual hashes (pHash, dHash, aHash), and semantic embeddings.

  →
• 05

  API reference — audio

  Audio fingerprinting — Wang (Shazam-style), Panako, Haitsma, neural embeddings, and watermark detection.

• 07

  Rate limits

  Per-IP demo quotas, authenticated defaults, and the X-RateLimit / Retry-After headers UCFP returns.

  →
• 08

  Examples

  End-to-end recipes — dedup a pretraining corpus, gate image uploads, and match audio against a catalogue.

  →
• 09

  SDK — JavaScript

  Install the @ucfp/client npm package and call every modality from Node, Bun, Deno, or the browser.
