TOTP / 2FA API

healthy 3,707 Subscribers

Add and test two-factor authentication without wrangling a crypto library. Generate a fresh base32 secret with a ready-to-scan otpauth URI, compute the current time-based one-time code (RFC 6238), verify a code submitted by a user with an adjustable drift window, or build an otpauth:// URI for any secret. Supports SHA-1, SHA-256 and SHA-512, 6 to 8 digits and a custom period, and is fully compatible with Google Authenticator, Authy, 1Password and other authenticator apps. Pure server-side computation with no third-party upstream, so responses are instant and the service is always available. Ideal for adding 2FA to apps, authentication tooling, QA and testing, and no-code automation.

Temp Mail API — oanor API marketplace

Temp Mail API

Disposable / temporary email as an API — no key, no signup. Spin up a throwaway mailbox in one call (you get back the address plus a token), then receive real inbound email and read it: list the inbox, open any message with its full HTML and plain-text body and attachments, mark messages seen, delete a single message, or delete the whole mailbox when done. List the available mailbox domains and look up account details (quota, usage). Perfect for sign-up flows, OTP / verification-code capture, QA and end-to-end test automation, and throwaway registrations. Inbox endpoints use a per-mailbox token returned by /v1/account/new (pass it as ?token= or an Authorization: Bearer header). Every call is live (no cache). 9 endpoints, backed by the public mail.tm service. Mailboxes are ephemeral. No upstream key, no cache.

 Bcrypt API — oanor API marketplace

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.

 JWT API — oanor API marketplace

JWT API

A fast, fully-local JSON Web Token toolkit: sign a JSON payload into a JWT, verify a token signature together with its exp and nbf claims using a constant-time comparison, and decode a token header and payload without verifying. Supports the HMAC algorithms HS256, HS384 and HS512, automatically adds the iat claim and an exp claim from expires_in. Built on Node crypto and secrets are never logged, so responses are instant, private and always available. Every endpoint accepts input via the query string or the request body. Ideal for authentication, API gateways, session and token tooling, microservices and webhooks.

 Shentu API — oanor API marketplace

Shentu API

Live on-chain data for Shentu (chain id shentu-2.2) — the security-focused Cosmos-SDK Layer-1 of the CertiK ecosystem, whose native token is CTK — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated CTK, commission rate and jailed flag. The supply endpoint returns the total CTK supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. Token amounts are converted from base micro-CTK (6 decimals) into whole CTK, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and security-infrastructure ecosystem. Live keyless upstream. 5 endpoints.
