title: Evangelist Network Insights API
version: 1.2.0
summary: Sixteen years of API research as one API.
description: 'The API Evangelist network — 5,000+ stories, 77 topic areas, 2,400+ governance building
blocks (guidance, rules, policies, standards, strategies, schema, properties, experiences,
lifecycle), conversations, videos, white papers, tools, timelines, services, and the API
vocabulary — served as a single, searchable REST API.
**Tiers.** The API works without a key on the free tier (5 req/s, 1,000 req/day). Requests
from apievangelist.com network sites get the internal tier automatically. Higher-limit keys
are available by request — email info@apievangelist.com.
**Providers.** The API provider catalog (4,500+ companies) intentionally lives on
[APIs.io](https://apis.io/developer/) — this API covers API Evangelist''s own research
network and does not duplicate it.
**MCP.** Every resource here is also available as MCP tools at
`https://mcp.apievangelist.com/mcp` (Streamable HTTP), including concierge tools
(`get_overview`, `guide_topic`) that bundle curated guidance for a topic.

q1_note: Q1 partial (~316 cos) + method-drifted vs Q2; served flagged, NOT diffed. See time-series.md.
sources: jobs + press (F1000). Provider/blog corpus extraction pending — see ingestion-evaluation.md.

adoption_basis: recomputed company counts from cleaned stacks
corpus_audit:
date: '2026-08-06'
withheld_companies: 113
reason: Attribution audit of all 879 job corpora found these accounts holding another company's job board — the pull matched on company NAME and followed a vendor or partner's board. Per-company demand figures for them are withheld.
caveat: Aggregate figures below — dimensions, adoption and provider_demand — were computed before this audit and still include the withheld corpora. They are being rebuilt.
