Pre-execution safety oracle for agent actions: submit the tool call you are about to run (shell, http, sql, file, code, env) plus your stated intent, and get a machine-enforceable verdict before you execute it. Decodes what the call does, flags the danger toolkit (rm -rf, reverse shell, curl|sh, SSRF to cloud metadata, credential reads, DROP/DELETE-without-WHERE, path traversal, dynamic eval), and binds it to your intent (allowedHosts/allowedPaths/readOnly/noNetwork) - only a fully pinned, clean, intent-matched call is auto-exec-safe. Hybrid: a deterministic, uninjectable detector engine (authoritative) plus an LLM classifier that can only raise the risk. Fails closed. Detection of known-dangerous patterns, not a proof of safety; it never executes the call.

How much of an ERC-20 token a spender is approved to move from an owner's wallet, via allowance, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The approval read every DeFi, swap and trading agent makes before (and after) a transaction to know if an approve is needed. Live public RPC; one paid call at $0.001.

Give this API any text or binary data and it instantly returns its fingerprint under whichever hash algorithms you choose — SHA-256, SHA-512, MD5, BLAKE2, CRC32, and more. It also signs data with a secret key (HMAC) and, most importantly, safely verifies whether an incoming signature matches — using a timing-safe comparison that prevents secret-leaking attacks. Language models cannot perform hashing: they produce a string of the right length and character set that looks correct but is simply wrong. Every webhook verification, idempotency key, cache fingerprint, or integrity check that relies on a hallucinated hash is silently broken. This API is the cure.
