What it is

TechStackIntel is a technographics API for 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. Responses include company data, cache status, schema version, evidence, and possibly 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 an email magic link; keys can be sent using X-Api-Key or Authorization: Bearer, and GET /v1/usage reports usage. Canonical taxonomy slugs cover company.stack, with schema version 1.1.0 and confidence from 0 to 1. Research submissions accept taxonomy slugs, evidence, and optional products. Coverage is not guaranteed for every domain; missing snapshots return not-found. Curl commands, a thin CLI wrapper, JSON previews, and batch lookup are provided.
