HMAC of a message under a key — Genesis402 / UnyKorn Operator Network

Generate an RFC 4226 counter-based HMAC one-time password from a base32 secret and counter. Configurable digits (6–10, default 6) and algorithm (SHA1/SHA256/SHA512, default SHA1). An invalid base32 secret is a clean 400.

Map a short product description to likely HS chapter/heading hints (electronics, apparel, coffee, pharma, …). Keyword table only — not a binding customs classification; confirm before filing.

Call when an agent needs text decoded with html-named. No network and no LLM. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/html-named-decode first.

Call when an agent needs text encoded with html-named. No network and no LLM. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/html-named-encode first.

Call when an agent needs text decoded with html-numeric. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/html-numeric-decode first.

Call when an agent needs HTML sanitized to an allowlist of tags and safe URLs. No network. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/html-sanitize first.

Convert an HTML document to clean Markdown for LLM ingestion: strips scripts, styles and navigation chrome, preserves headings, lists, tables and links. Deterministic for identical input.

Call when an agent already has HTML and needs clean markdown. No network. Optional url is a base for relative links only. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/html-to-md first.

Convert a supplied HTML string into deterministic, LLM-ready Markdown. Preserves headings, links, lists, emphasis, and code without fetching a URL or invoking an AI model. Input is bounded to 2,000,000 characters.

Call when an agent needs HTML converted to plain text (scripts and styles removed). No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/html-to-text first.

Decode HTML entities (named, decimal and hex numeric references) back into plain text.

Encode text to HTML entities so it can be safely embedded in markup. By default uses hex numeric references; set useNamedReferences for named entities (&, ©) or encodeEverything to encode every character.

SSRF-safe public GET with status, headers, and size-capped JSON/text body for agent tool use

Public URL status, latency, and response header subset for uptime and health agents

Public URL status, latency, and response header subset for uptime and health agents

Call when an agent needs response headers from an SSRF-safe HEAD or GET of a public URL. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/http-headers first.

Hacker handles: Compact aliases for fictional hackers, pilots, and netrunners.

Delivers real-time trending technology articles, developer discussions, and venture announcements directly from HackerNews.

Tokenizes each claim and its supplied evidence, removes a small declared English stop-word list, and reports the fraction of unique claim tokens present in evidence. Coverage below a supplied threshold is flagged. This is lexical grounding screening only: overlap does not prove truth, low overlap does not prove hallucination, and the service does not retrieve or validate evidence.

Hamming distance — the number of positions at which two EQUAL-LENGTH strings differ — plus a normalized similarity. Strings of unequal length are a clean 400.

Generate a random handshake sequence (numbers and symbols) for secure connections.

Adds simple degree-days from caller-supplied daily temperatures to an existing accumulation, then marks days that meet a supplied maturity threshold, crop-moisture interval and maximum rain constraint. It does not obtain a forecast, model crop physiology, inspect a field or guarantee harvestability.

Compute SHA-256, SHA-512, SHA-1 or MD5 checksum for UTF-8 text and return hex plus Base64 digests. Use for compute sha256 checksum, integrity verification, content fingerprints, cache keys, deduplication and agent pipelines.

Computes a SHA-256, SHA-512, or MD5 hash digest of provided text.

Compute cryptographic digests of a string. POST {"input":"...","algorithms":["sha256"]} and receive one hex digest per requested algorithm. Supports sha256, sha512 and keccak256. Deterministic, no storage, no upstream calls.

Hash text: keccak-256 (Ethereum) and SHA-256, plus byte length. POST JSON {"text": "…"} up to 20,000 characters. Pure computation, nothing stored, no cache.

Cryptographic SHA-256 hash & HMAC timestamp audit seal for AI agent actions

Compute a cryptographic digest (SHA-2, SHA-3, BLAKE2, and legacy SHA-1/MD5/RIPEMD-160) of some data. The input may be utf8/hex/base64/base64url and the digest is returned as hex/base64/base64url.

Global (or per-country) natural-hazard / disaster alert signal (optional ?country=)

Header semantics audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
