MAC Vendor API

4,033 Subscribers
Identify the manufacturer behind any MAC address. Look up a MAC or OUI to get the assigned vendor, its short name and the exact assignment block (/24, /28 or /36) using the official IEEE registry, search the registry by vendor name to find all of a company’s OUIs, or generate random valid test MAC addresses for a given vendor. MAC addresses are accepted in every common format — colon, hyphen, dot or bare hex — and bare OUIs work too. Built on the open IEEE OUI dataset (~57,000 assignments) and served entirely in-memory, so responses are instant and the service is always available. Ideal for network scanning and monitoring, IoT and device identification, security and asset inventory, NAC and devops tooling.

MAC Address API
MAC-address (EUI-48) tooling as an API, computed locally and deterministically. The parse endpoint validates a MAC address given in any common notation — colon, hyphen, Cisco dotted or a bare run of 12 hex digits — and returns it in every standard format, split into its OUI (the first three bytes, assigned to a hardware vendor) and its NIC (the last three, device-specific) parts, plus the 48-bit integer value. The analyze endpoint reads the control bits of the first octet: the least-significant bit is the I/G bit that marks a unicast or multicast address, and the next bit is the U/L bit that marks a universally (vendor-assigned) or locally administered address, and it flags the broadcast address ff:ff:ff:ff:ff:ff. The eui64 endpoint derives the modified EUI-64 interface identifier — flipping the U/L bit and inserting FF:FE in the middle — and the resulting IPv6 link-local address (fe80::/64) used by stateless address autoconfiguration. Vendor name lookup needs the IEEE OUI registry and is not included. Everything is computed locally and deterministically, so it is instant and private. Ideal for networking, IoT, device-management, monitoring and security app developers, MAC-normalisation and IPv6 tools, and networking education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is MAC-address tooling; for IPv4 subnetting use a subnet API and for DNS records a DNS API.

Sui Network & Epoch API
Read Sui's network state live from a public Sui fullnode JSON-RPC endpoint — no key. Sui is a high-throughput, object-centric Move Layer 1; its ledger advances in checkpoints (its block equivalent) and reconfigures each epoch. The Sui on-chain reader resolves owned objects and the validator reader surfaces the validator set, but neither exposes the latest checkpoint, the epoch-level network economics, or a coin type's metadata. This opens that. Read the latest checkpoint with its epoch, sequence number, digest, lifetime network transaction count and rolling gas-cost summary (computation and storage costs in SUI); read the current epoch's economics — reference gas price, total stake in SUI, active validator count, storage-fund balances and protocol version; and resolve any Move coin type (e.g. 0x2::sui::SUI) to its on-chain metadata — decimals, name, symbol, description and icon. The network / epoch / coin-metadata layer for Sui explorers, wallets, fee estimators and analytics. Distinct from the Sui on-chain object reader, the validator reader and the Move-module reader. Live from RPC; short cache only.

Solana Network Status API
The live performance and monetary health of the Solana blockchain, read straight from public Solana RPC nodes, no key. Solana is one of the highest-throughput blockchains in crypto, and its network state — how fast it is processing transactions right now, where it is in the current staking epoch, how much SOL exists and how fast new SOL is being minted — is the heartbeat that traders, validators and builders watch. The status endpoint is the live dashboard: the current epoch and how far through it the chain is (with an estimate of the time left until the next epoch), the absolute slot and block height, the lifetime transaction count, the current transactions-per-second, the average slot time and the node health. The supply endpoint returns the SOL money supply — total, circulating and non-circulating — with the circulating share and the live inflation rate broken into its validator and foundation parts. The performance endpoint returns the recent throughput samples — transactions, slots and TPS over the last few one-minute windows — so you can see whether the chain is speeding up or slowing down. This is the Solana network performance / monetary cut, distinct from the Solana validators feed (which ranks validators by stake and measures decentralisation), and from the price, DeFi and on-chain-token feeds. SOL amounts are in whole SOL (converted from lamports); rates are percentages; everything is live. Built for crypto dashboards, trading and infrastructure-monitoring tools.

IP Exposure API
See what any host exposes to the internet — as an API over Shodan's free InternetDB. Give it an IPv4/IPv6 address (or a hostname, which is resolved to its IP) and get that host's attack surface: the open ports (annotated with common service names), the products and technologies detected on it (CPEs), its reverse hostnames, Shodan's classification tags, and the known vulnerabilities (CVE identifiers) observed on its services. A dedicated vulnerabilities view returns just the CVEs and whether the host appears vulnerable. It is fast, requires no key, and is built for security, asset-discovery, external attack-surface monitoring and reconnaissance workflows. A network-exposure / attack-surface resource — distinct from IP geolocation (where an address is), the IANA port registry (what a port number means) and CVE databases (what a vulnerability is). Data from Shodan InternetDB (free / non-commercial use).
