TechStackIntel
What it is
TechStackIntel is a technographics API for retrieving curated company technology-stack snapshots and taxonomy-backed lookups. Its launch catalog contains 200 curated company domains. GET /v1/lookup handles one domain, while POST /v1/batch/lookup accepts multiple domains through the same lookup pipeline. A single response includes a nextAction envelope and data containing company, cache status, and schema version; responses can include evidence and optional product data. Anonymous access allows 60 requests per hour per IP. Free API keys allow 120 requests per hour, with grace up to 160 before the cap returns. Signup begins with email magic-link authentication, and keys can be sent through X-Api-Key or Bearer authorization. A valid key can query GET /v1/usage. Taxonomy slugs use schema version 1.1.0 and a confidence scale from 0 to 1. The service also accepts research submissions with taxonomy slugs, evidence, and optional products.
