The Free plan includes API access. 2. app.theirstack.com > Settings > API Keys > Create API key (expiry date or Never; shown once) 3. Send it with every request: header: Authorization: Bearer . 4. Make a first call: Get Email Preferences. Keep the key in an environment variable, never in the command. ``` curl -X GET "https://api.theirstack.com/v0/email-preferences" \ -H "Authorization: Bearer $THEIRSTACK_API_KEY" ``` ## Where the docs live What Where Documentation [theirstack.com/en/docs](https://theirstack.com/en/docs) API reference [theirstack.com/en/docs/api-reference](https://theirstack.com/en/docs/api-reference) OpenAPI spec [api.theirstack.com/openapi.json](https://api.theirstack.com/openapi.json) llms.txt [theirstack.com/llms.txt](https://theirstack.com/llms.txt) Base URL `https://api.theirstack.com` MCP server `https://api.theirstack.com/mcp` ## Strengths and limits ### Where it fits - Hiring signals (who is hiring for role X / technology Y) - Technographics inferred from job posts - TAM sizing by tech stack + firmographics with cheap counts - Webhook feeds of new/closed jobs and new matching companies ### Where it falls short - Contact data (emails/phones) - it sells company and job records, not people - Website-crawl technographics (BuiltWith-style tag detection) - Real-time news/funding signals ### Worth knowing - Job Search requires a date or company filter; a company filter with 50+ values also needs a posted\_at filter (OpenAPI /v1/jobs/search). - Repeated API calls for the same records are charged every time; the 90-day free re-view applies only to app company credits, not API credits. - Preview/blur mode (blur\_company\_data=true, 0 credits) is being retired over the API: only workspaces created before 2026-08-11 that have paid at least once keep it. - Counting now costs one record (1 or 3 credits) unless nothing matches. - Free tier is capped at 400 requests/day and 25 results x 5 pages; one payment ever lifts you to paid limits. 5 moreShow fewer - Subscriptions cannot be changed in place: cancel and resubscribe; no proration. Buying a bigger package upfront is the only discount below 5M credits. - App exports cap at 200 jobs per company per export. - Not SOC 2 or ISO 27001. - Terms forbid building a competing product or reselling data in a way that competes with TheirStack. - The MCP server exposes account-changing tools (cancel\_subscription, cancel\_billing\_invoice, delete\_company\_list, archive\_webhook). Give automations a scoped key and review tool approvals (live tools/list, 2026-10-25). ### Our take Our signal-system playbook uses TheirStack for technographic account lists and job-posting signals, on an API key the client owns. In July 2026 we measured that a count in preview (blur) mode cost 0 credits, while every revealed company row cost 3 API credits, including companies we had pulled before. TheirStack has since limited preview mode to older workspaces that have paid at least once, so on a new account a count costs credits. ## Who should use it Use TheirStack for Hiring signals (who is hiring for role X / technology Y) Look elsewhere for Contact data (emails/phones) - it sells company and job records, not people ## If TheirStack is not the answer Other Signals tools in this directory, each with its own review.

Free tier: 50 company credits + 200 API credits every month. - **Keep the key out of your code**API key. It is sent as: header: Authorization: Bearer . - **Design around the rate limit**Per user, sliding windows, HTTP 429 on breach. - **Know the catch before you scale**Job Search requires a date or company filter; a company filter with 50+ values also needs a posted\_at filter (OpenAPI /v1/jobs/search). ## Want us to build it for you?
