FAQ

Honest answers.

Do I need an API key to try it?
Yes. Every call from a skill, MCP server, or your own script authenticates with an API key. Create one at /profile/api-keys after signing in. The key is what your agent sends as a bearer token.
What does the free tier cover?
Every account gets free credits on signup. 1 credit = 1 full company profile (contact, team, case studies, sources). Search and browse on the website are always free; only API responses from /v1/get consume credits.
How is firm data sourced and how fresh is it?
The catalog is built from public web data — firm websites, third-party directories, public business registries — and refreshed continuously. Classification (industry / services / size / geography) is done with LLMs over the firm's own pages and is re-checked on update. Stale rows are dropped; new firms enter as they're crawled.
Which AI agents work?
Anything that supports the Skills convention — Claude Code, Codex, Cursor, GitHub Copilot, Gemini, Cline, Droid, Goose, Windsurf, and a dozen more. The skill is plain markdown + curl invocations; agents that don't support skills can call the API directly.
Is the data US-only?
Yes for v1. The catalog explicitly excludes non-US firms; it's scoped to US professional-services as a focused, defensible target. Other regions are on the roadmap.
How is this different from a Google search?
Structured filters, not keyword matching. Industry across 22 categories, services across an 89-tag taxonomy with evidence levels, classified firm size, third-party rating presence, geography served — all queryable with a single filter string. You ask for “mid-size IT consultancies in TX with a Clutch listing and 4★+ rating” and get a clean list, not 200 search results to re-rank.
What happens if a firm I want isn't in the catalog?
/v1/get returns a 404 (uncharged) so your agent can branch. Coverage is ~118k+ US firms today and growing; if you need a specific firm indexed, email artur@servicegraph.co and we can prioritize.
