Insights · Q3 2026
The catalog shows what APIs exist. Insights shows who is hiring for them.
The rest of APIs.io is the supply side: which APIs are published and how good they are. Insights is the demand side. We read companies' own job postings for the APIs, tools, standards and regulations they name, then join that back to the providers in the catalog.
984companies with enough postings to count (775 Fortune 1000, 209 API providers)
343,299job postings read
6,572companies with a technology profile, from postings or their own blogs

How to read these numbers. A job posting shows hiring intent, not production use. Every term is matched on whole words, sampled against the postings themselves, and given a human verdict before it is quoted. Ambiguous words like Teams, Office and Project are not counted as products. Q3 2026 is the first quarter in the series, so nothing here is rising or falling yet. The Q4 pull runs in November and will be the first quarter that reports movement.
## What you can ask it
Insights is part of the [Understanding plan](/developer/plans/). It is served by the same [REST API](/developer/api) and [MCP server](/developer/mcp-server) as the rest of APIs.io.
