How this service works

General-purpose text, Unicode and date utilities for AI agents: homoglyph folding and spoofed-domain detection, Unicode script detection, NFC/NFD normalization, grapheme counting, date description (weekday, ISO week, quarter, leap year), business-day counting, slugify, FNV-1a hashing, Shannon entropy, string format detection (uuid, email, url, ipv4, jwt, iban), byte-encoding detection and human-readable byte sizes. Pay per request in USDC on Base via x402 - no signup, no API key, no KYC.

Output

Returns a JSON object with the input string's character length, its FNV-1a 32-bit hash as a lowercase hex string, and its FNV-1a 64-bit hash as a lowercase hex string. Example: {"length":5,"fnv1a32":"3617a694","fnv1a64":"a430d84680aabd0b"}.

Example use cases

Hash-based cache key generation

“Generate an FNV-1a hash for the string 'user:profile:42' so I can use it as a fast cache lookup key.”

String deduplication fingerprinting

“I need to fingerprint the text 'order-confirmation-email-template-v2' with FNV-1a to check for duplicates in my dataset.”

Consistent hash routing

“Compute the FNV-1a 32-bit hash of 'shard-partition-key-west-us' so I can use it for consistent hash ring routing.”

Endpoint

When to prefer

Choose this endpoint when you need a fast, deterministic, non-cryptographic hash of a text string — particularly FNV-1a, which is popular for hash tables, cache keys, and consistent hashing. Ideal when you don't need cryptographic security (use SHA/MD5 for that) but want a well-known, compact 32-bit or 64-bit fingerprint. Also useful when you want both hash lengths in a single call and need no API key or signup overhead.

Side effects

Missing required 'text' query parameter returns an error
Empty string input may return zero-hash values
Extremely long strings may exceed query parameter length limits
Network or worker timeout for unusually large inputs
