Compute cryptographic hashes (MD5, SHA-1, SHA-256/384/512, SHA-3, RIPEMD-160) in hex or base64, generate HMAC signatures for webhook and message authentication, and mint v4 UUIDs. All server-side and deterministic. Handy for integrity checks, signing, cache keys, deduplication and id generation.

Fast Hash API
Non-cryptographic hash functions — the fast hashes used in hash tables, bloom filters, sharding, deduplication and cache keys. Give it text (UTF-8) or raw bytes as hex and it returns the digest under every algorithm at once, or under one named algorithm: FNV-1 and FNV-1a (32- and 64-bit), djb2, sdbm, Jenkins one-at-a-time, CRC-16 (CCITT-FALSE and ARC/IBM), Fletcher-16 and Fletcher-32, and MurmurHash3 (x86 32-bit, with an optional seed). Each digest is returned in hex and as an unsigned integer. Everything is computed locally and deterministically, so the same input always maps to the same hash — exactly what you need for stable bucketing and lookups. These are deliberately NOT for security: they are fast and well-distributed, not collision-resistant. Ideal for hash-table and bloom-filter implementations, consistent sharding and partitioning, cache and dedup keys, A/B bucketing, and teaching how hashing works. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. For cryptographic hashes (SHA, MD5, HMAC) use a hash API, and for CRC-32/Adler-32 integrity checksums use a checksum API.

Bcrypt API
Hash and verify passwords with bcrypt, server-side. Generate a salted bcrypt hash at a cost factor you choose (4–14), check a plaintext password against an existing hash, or inspect a hash to read its bcrypt version, cost factor and salt. Fully compatible with bcrypt hashes from PHP ($2y$), Node, Python and others, so you can verify and migrate existing credentials. Pure server-side computation with no third-party upstream, so it is always available — and it offloads the deliberately CPU-intensive hashing work from your own servers. Ideal for adding password authentication, credential migration, auth tooling, testing and no-code backends.

UUID API
A fast, fully-local identifier-generation toolkit: create UUID v4 (random), v7 (time-ordered and lexicographically sortable), v3 and v5 (name-based, deterministic via MD5 and SHA-1 over a namespace plus name) and the nil UUID; generate ULIDs (sortable, Crockford base32); generate nanoids (URL-safe, with custom alphabet and size); and validate any UUID, reporting its version and variant. Every endpoint accepts input via the query string or the request body. Built on Node crypto, no third-party upstream, so responses are instant and always available. Ideal for databases and primary keys, distributed systems, idempotency and correlation keys, and general developer tooling.

WEMIX API
Live EVM on-chain data for WEMIX (chain id 1111) — the gaming-focused public Layer-1 built by Wemade, whose native token is WEMIX — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the WEMIX balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole WEMIX with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and game-economy analytics across the WEMIX ecosystem. Live keyless upstream. 5 endpoints.

Frequently asked questions
Quick answers about pricing, quotas, and integration.
How do I get an API key for Hash API?
Sign up for free at oanor.com, generate an API key from the developer dashboard, and call Hash API with the x-oanor-key header. No credit card needed for the free tier.
What's the rate limit for Hash API?
Free tier allows 1 request per second. Paid plans scale up to 50 requests per second on the Mega tier. Hard limits return HTTP 429 above the quota — no surprise overage charges.
How much does Hash API cost?
Hash API has a free tier with 100 calls / month. Paid plans start at €4.00 / month with higher quotas and faster rate limits.
Can I cancel my subscription anytime?
Yes. Plans are billed monthly and you can cancel anytime from your billing dashboard. No long-term contracts and no cancellation fee.
Is Hash API GDPR-compliant?
All requests to Hash API go through our EU-based gateway. Your upstream API key never leaves our server and no personal data is shared with the upstream provider beyond the request you send.
