How this service works
Persian and Iranian utilities for AI agents, plus general text/Unicode tooling. Jalali (Solar Hijri) calendar conversion, Iranian national ID / SHEBA / bank card / postal code / economic code validation, province and city lookup, official public holidays, Persian text normalization, keyword extraction, sentence splitting, similarity, HTML stripping, RTL fixing, Unicode homoglyph folding, script detection, NFC/NFD normalization, grapheme counting, date description, business-day counting, slugify, FNV-1a hashing, Shannon entropy, format and encoding detection, byte sizes. Pay per call in USDC on Base via x402 - no signup, no API key, no KYC. The same tools are also exposed as MCP tools at /mcp.
Output
Returns a JSON object containing the FNV-1a hash value of the input text, typically as a numeric or hex digest representation suitable for use as a fingerprint, cache key, or checksum.
Example use cases
Cache key generation for Persian text
“I need a fast hash to use as a cache key for this Persian string: 'جمهوری اسلامی ایران' — can you compute the FNV-1a hash for me?”
Deduplication fingerprinting pipeline
“Hash this product description so I can fingerprint it for deduplication: 'این محصول با کیفیت بالا تولید شده است'.”
Bucket assignment for text sharding
“I'm sharding data by string hash — give me the FNV-1a hash of the string 'user_profile_tehran_42' so I can assign it to the right bucket.”
Technical details
Endpoint
POSThttps://irantools.johnaio281.workers.dev/api/iran/fnv_hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, non-cryptographic hash of a text string — especially Persian or Unicode text — and want a pay-per-call model with no API key or signup. Prefer it over SHA/MD5 when FNV-1a compatibility is specifically required (e.g. matching hashes produced by other FNV implementations). Useful in pipelines already using other IranTools endpoints.
Side effects
- Missing required 'text' field returns a 400 or validation error
- Empty string input may return hash of empty input or an error
- Payment failure (402) if USDC balance is insufficient on Base
- Network timeout on the Cloudflare Workers edge
- Unexpected Unicode normalization differences affecting hash output
