API Evangelist Sector Report
The State of Headless APIs
108 headless providers scored — the architecture whose whole promise is that the API is the product, tested against the evidence. The tier that invented the word finishes last: headless CMS averages 39.1 against 49.4 for the monoliths it was funded to disrupt, and WordPress out-publishes 33 of the 34 headless CMS vendors in the study. Not one provider in 108 signals idempotency, in a cohort selling checkout as an API.
