Company name search across jurisdictions. jurisdiction=lei searches the global GLEIF LEI database (all countries); jurisdiction=jp searches the official Japan National Tax Agency corporate registry. Returns registered legal names, identifiers, and addresses. KYB / counterparty verification primitive.

Check an open-source package for known vulnerabilities via the OSV database (Google Open Source Vulnerabilities). Pass package name, ecosystem (npm, PyPI, Go, crates.io, Maven, RubyGems, etc.) and optional version. Returns vulnerability IDs, summaries, severity and fixed versions. Essential pre-install check for coding agents.

Real-time cryptocurrency spot price in USD, aggregated as the median across Coinbase, Binance and Kraken with cross-exchange spread. Supports BTC, ETH, SOL. Deterministic multi-source aggregation for trading and treasury agents.

Screen a person or company name against three major sanctions lists in one call: US OFAC SDN, EU consolidated financial sanctions, and UN Security Council consolidated list — 60,000+ names including aliases. Fuzzy matching with similarity scores. Returns matched entities with list source and sanction programs. Compliance primitive for agents sending payments.

Generate a similarity key for a person or company name: a normalized phonetic fingerprint that collapses spelling variants, transliterations and legal-suffix noise to the same key. Two names sharing a key are likely the same entity. Deterministic, no LLM. For dedup, entity resolution and record linkage across datasets.

Compare DeFi pool yields across chains with built-in risk screening. Filters by chain, asset and minimum TVL, and flags trap yields — unsustainable APY, reward-token dependence, low TVL, impermanent-loss and ML-predicted decline — so agents don't chase headline numbers into losses. Data from DefiLlama.

Search US FDA enforcement reports (food and drug recalls) by product keyword. Returns recall number, product description, recall reason, classification (I/II/III), status and dates. Compliance check for commerce agents selling or sourcing consumables in the US.

Compare two names and return a similarity score (0-1) plus whether they share a phonetic similarity key. For deduplication and fuzzy record matching — e.g. 'Bob Smith' vs 'Robert Smyth'. Deterministic, no LLM.

Ownership-chain sanctions screening: resolve a company (by LEI or name), walk its corporate ownership chain via GLEIF Level 2 relationship data (direct parent, ultimate parent), and screen every entity in the chain — including transliterated and alternate names — against OFAC SDN, EU consolidated, and UN Security Council lists. Catches the case where your counterparty is clean but its parent is sanctioned. Unique combination of KYB registry resolution and sanctions screening.

Check a stablecoin's current peg deviation. Returns live price, deviation in basis points, and a depeg flag (>50bps). For agents holding or accepting stablecoins that need to detect a depeg before transacting. Data from DefiLlama.
