Contract Verification API
Check whether any EVM smart contract source code is verified and pull its ABI, source files and deployment details, keyless. Give it a chain id and contract address and get the verification status (full / partial / not verified), the compiler and contract name, the deployment info (deployer, transaction, block), the contract ABI (the JSON interface every integration needs), and the verified Solidity source. Live, nothing stored. The contract-verification / ABI layer for security, due-diligence, block-explorer, wallet and dapp tooling — backed by the open Sourcify registry, distinct from price, TVL and chain-registry APIs.

Keybase Identity API
Live cryptographic social-identity lookup from Keybase — no key, nothing cached. Keybase links a person's identities together with public-key cryptography, so this answers "who is this account, really, and what else are they?". The user endpoint takes a Keybase username and returns the profile (full name, location, bio, picture), every verified identity proof — the Twitter, GitHub, Reddit, Hacker News, Mastodon, website and DNS accounts that user has cryptographically proven are theirs — plus their on-file cryptocurrency addresses (Bitcoin, Zcash and more) and PGP key fingerprint: Keybase user "chris" resolves to Chris Coyne in Maine, with proven twitter/github/reddit @malgorithms and a Bitcoin address. The lookup endpoint runs the reverse — give it a GitHub, Twitter, Reddit or Hacker News handle, a domain or a PGP fingerprint and it finds the Keybase user who proved it, so a bare GitHub handle resolves to a full verified identity. The proofs endpoint returns just the connected-accounts graph and crypto addresses. This is the identity-verification and social-graph layer for any trust, onboarding, anti-impersonation, social or crypto app — proven links, not claimed ones. Live from Keybase, nothing stored. Distinct from single-platform profile APIs — this is the cross-platform proven-identity graph. 4 endpoints.

Phone Validation API
Validate, parse and format phone numbers using Google libphonenumber: validity check, E.164 / national / international / RFC-3966 formats, country and calling code detection, and line type (mobile, fixed-line, VoIP, toll-free, premium-rate). Covers every country.

Email Validation API
Verify email addresses without sending anything: RFC syntax validation, live MX-record lookup, disposable/throwaway detection (5,500+ domain blocklist), role-account and free-provider flags, "did you mean" typo suggestion, and a 0–100 deliverability score.
