Checks whether npm, PyPI, or crates package names actually exist in their registries and returns closest real alternatives for hallucinated (non-existent) package names.

Verifies that a cited EU law instrument, article, and quoted text are accurate before publishing a claim, returning the official article text and a EUR-Lex link.

Returns EU AI Act articles (with headings, excerpts, and EUR-Lex links) that mention a specific obligation topic for a given actor role and risk tier.

Decodes a raw Bitcoin transaction hex or PSBT and returns inputs, outputs, script types, addresses, vsize, fee rate, RBF flags, dust outputs, non-standard sighash flags, and unsigned inputs — offline, no network access.

Decodes raw Ethereum or Base transaction bytes or calldata against standard interfaces (ERC-20, ERC-721, ERC-1155, WETH, EIP-2612 Permit, Permit2) and returns the decoded method signature, typed parameters, value in wei, and spec links.

Checks whether CVE identifiers are real, published, or rejected — catching hallucinated vulnerability references before an agent acts on them.

Verifies that a specific package version exists in npm, PyPI, or crates.io, returning its publication timestamp, deprecation/yanked status, artifact hashes, and optional SRI/hex digest comparison.

Looks up chain context for Bitcoin transaction inputs — checking if each prevout exists, is spent, its value in satoshis, and its confirmation count — before signing.
