Thirteen governed tools

A tool catalog built for agents, not a raw query console.

Each tool does one job well — search, count, resolve a market, reveal a contact, or hand a finished export to the workspace owner.

Verify

Exports run a live SMTP check at download time, and uploaded lists can be verified through the same engine via the API. Verdicts come back per address: valid, invalid, catch-all, or unknown.

Export

Exports are verified at the moment of download. Credits are only spent when contacts are revealed or an export is created — every spend is logged.

Everything an agent does over MCP is also a clean REST endpoint. Signed, retried webhooks fire on exports, verifications, and low credits — no polling.

Anything that speaks MCP: Claude (Desktop, Cowork, and Code), ChatGPT connectors, Cursor, Codex, Perplexity, Manus, OpenClaw, Hermes, and any custom runtime. There's also a REST API and a CLI on npm for everything else.
Counts, searches, and masked previews cost zero credits — on every plan, including Free. CLI counts don't even need a key. Credits are only spent when contacts are revealed or an export is created.
Search, count, and preview tools are free. Reveal and export tools draw from the same workspace credit pool as the app — one credit per deliverable contact (valid, or catch-all/risky if opted in), zero for invalid. Every spend is logged.
Free: 10 req/min on preview-class tools. Starter: 30 req/min. Pro: 120 req/min. Scale: 600 req/min with a priority queue. API and MCP are included on every paid plan — limits scale with the tier, never gated to a single plan.
Yes. Exports run a live SMTP check at download time, and uploaded lists can be verified through the same engine via the API. Verdicts come back per address: valid, invalid, catch-all, or unknown.
Yes — published on npm as 'argorant'. Run npx argorant count "..." with zero setup, or npm install -g argorant. Full reference at argorant.com/docs/cli.
Keys and OAuth grants are workspace-scoped. You control which tools an agent may call, plan limits cap throughput, previews are masked by default, and every action lands in an audit log your admin can review.
