Advice Slip vs Personality.fyi

Advice Slip returns a single short, sometimes humorously literal, piece of advice as JSON — either a random slip or a specific one by its numeric ID. A live GET against the real host, api.adviceslip.com, redirected to HTTPS and returned genuine JSON while carrying Access-Control-Allow-Origin: *, resolving cors unknown -> yes; no key was required, reconfirming auth None. A fully free, keyless novelty API — pricingModel free.

Personality.fyi is a small, static-data JSON API for the 16 MBTI types and the OEJTS personality test's items and scoring, explicitly marketed as "Free · No auth · No LLM." A live GET against the real gateway, personality.fyi/api/v1/types, returned a genuine list of the 16 MBTI types while carrying Access-Control-Allow-Origin: *, reconfirming both cors yes and auth None — no base-field corrections were needed. CC0 public-domain data with no paid tier — pricingModel free.
