Verdix quick ($0.02): call before an agent pays or sends funds to an EVM address on Base, e.g. an x402 payTo, a withdrawal or a pasted address. Checks OFAC sanctions, scam/phishing lists, live address poisoning, contract/deployer signals and address age. Returns safe/caution/danger with reasons: stop on danger, confirm on caution.
Verdix standard ($0.10): call before larger or repeated payments to an EVM address on Base, when an address-age read is not enough. Sanctions, scam/phishing lists, address poisoning and contract/deployer signals, plus on-chain behaviour analysis. Returns safe/caution/danger with reasons.
Verifiable Random dice — unbiased dice rolls bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.
Verifiable Random shuffle — a uniform Fisher-Yates permutation bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with original indices and a reproducible proof transcript.
Cryptographically-secure randomness with a receipt. GET ?bytes= returns hex (1-256 bytes); add ?min=&max= for a uniform integer in an inclusive range. Each response carries a request_id and timestamp — unbiased entropy an agent can cite to a counterparty, not a seeded PRNG. Need provable fairness over time? /rand/commit does commit-reveal (commitment now, value later).

Verifiable Random pick — string selection with or without replacement bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.

Unpaid probe of an x402 URL: pay, skip or recheck verdict on its live terms (payTo, network, asset, price), with an Ed25519-signed receipt. Never pays the target. $0.02 USDC on Base after 5 free checks per UTC day.
Classify a caller-supplied operation claim against caller-supplied evidence under deterministic rules and return a machine-readable handoff receipt. Use this when an orchestrator needs a consistent completion state before accepting an agent's work. VERIFIED_COMPLETE means the submitted evidence supports the submitted claim; QSL does not independently observe the underlying real-world action.

Verify an Ed25519 Solana signature (Phantom/Solflare signMessage) for a message and public key; signature in base58, base64 or hex. Local computation.
Verify an Ethereum signature: a personal_sign (EIP-191) message or EIP-712 typed data. Recovers the signer address and, if you pass one, confirms it matches. Local computation; EIP-1271 contract wallets are not covered.
Use when an agent must decide whether whoever is talking to it really controls a wallet: it recovers the address that signed a personal_sign (EIP-191) message and says whether it matches the one you expected. This is the check that turns a claimed address into a proven one. Do not use for EIP-712 typed data or for a contract signature (ERC-1271): this route verifies personal_sign.

Clearsigned — the trust layer with no stake in the outcome. Submit {claim, evidence[]}, receive an Ed25519-SIGNED, evidence-bearing receipt (verify offline against GET /pubkey; every receipt is chained in the public ledger at GET /ledger/verify). Flat price, verdict-independent; refunds only for failure to deliver. Current mode is honestly labeled in each receipt.
Fast verification endpoint for quick identity or data checks.
Verifies data or identities via a paid API on Base using USDC.
On-chain address risk scoring and intelligence. Analyzes any Ethereum, Base, or Sepolia address across 6 security signals: balance profile, transaction history depth, contract detection, bytecode analysis (self-destruct patterns, delegate calls), proxy detection (EIP-1967), and known-risky address matching. Returns a 0-100 risk score, severity-ranked flags, and full profile data in a single call.
Passive public web release security gate
Scores policy violations by severity for AI moderation and compliance workflows.
Email address verification: syntax, domain, MX records, disposable/free-provider detection, score
Does 0x1111111111111111111111111111111111111111 belong to allbirds.com? Evidence, not a guarantee. $0.002.
Check an exact npm or PyPI package version immediately before installation using current registry, vulnerability, malicious-package, withdrawal/deprecation, and verified provenance evidence. Returns ALLOW, REVIEW, BLOCK, or UNKNOWN with machine-readable reasons.
