Use before a coding agent installs an unfamiliar npm dependency. Returns current facts from the official npm registry: the version `npm install` resolves (dist-tags.latest), prerelease and deprecation status, engines.node compatibility with an optional target Node version (real SemVer evaluation), license, days since release, best-effort weekly downloads, repository URL and maintainer count. Facts only — no safety, trust, or malware verdict.

More from Agent Miner Tools & similar services
Agent Miner Tools · Shopping Budget Basket
agent-api-testnet.tim1712.workers.dev
Use when an agent already knows several products/categories a buyer needs and wants one real Shopify product for each need while staying within one overall item-price budget. Each need.query must already carry the important compatibility and preference details; this service does not reinterpret intent. Returns a cross-merchant basket plan with per-item checkout URLs. It is not a generic product search and does not create carts or checkouts.
Agent Miner Tools · NPM Install Preflight
agent-api-testnet.tim1712.workers.dev
Use before a coding agent installs an unfamiliar npm dependency. Returns current facts from the official npm registry: the version `npm install` resolves (dist-tags.latest), prerelease and deprecation status, engines.node compatibility with an optional target Node version (real SemVer evaluation), license, days since release, best-effort weekly downloads, repository URL and maintainer count. Facts only — no safety, trust, or malware verdict.
Agent Miner Tools · Shopping Product Search
agent-api-production.tim1712.workers.dev
Use when an agent already knows the product it wants and needs real current Shopify listings for a structured query. Returns normalized product/variant price, currency, seller, rating, product URL and checkout URL in upstream search-rank order, with an optional maximum item price. The query must already carry the compatibility and preference details. Not a recommendation engine, intent interpretation, web search, or cart/checkout.
