Mental health app developers, psychology researchers, and AI assistant creators share the same need: access to reliable and structured psychological data. This is exactly what the Psychology and Serenity API provides.
I go deeper into this mechanism in Your Thoughts Don’t Have to Run Your Life.
Why a Free Psychology API?
Evidence-based psychology too often remains locked away in academic silos. Popular science articles exist, but their metadata is not easily exploitable by software programs.
Our API fills this gap by exposing structured metadata from over 300 articles written by a CBT practitioner, covering the major themes of contemporary clinical psychology.
What the API Offers
1. Article Metadata (300+)
The `/api/articles` endpoint provides access to metadata for all our published articles. Each article is automatically categorised among 17 thematic categories: Attachment, Couples, Anxiety, CBT, Manipulation, Emotional Dependence, Breakups, and many more.
curl "https://psychologieetserenite.com/api/articles?theme=Attachment&limit=5"The response includes the title, description, category, publication date, estimated reading time, word count, and the full URL of the article. The full article content is never exposed — only metadata is returned.
2. Psychological Test Catalogue (25+)
The `/api/tests` endpoint exposes a catalogue of scientifically validated psychological tests hosted on our dedicated platform. Each test includes a title, description, estimated duration, number of questions, and category.
curl "https://psychologieetserenite.com/api/tests?category=anxiety"Available categories cover: personality, anxiety, relationships, ADHD, OCD, phobias, childhood schemas, depression, and personal development. Questions and scoring scales are not exposed.
3. Research Statistics
The `/api/stats` endpoint provides aggregated data from published research: attachment style distribution, anxiety disorder prevalence in France, CBT effectiveness according to meta-analyses, and most common early schemas.
curl "https://psychologieetserenite.com/api/stats"Each dataset references the source study and sample size.
Concrete Use Cases
Mental health applications. Integrate links to relevant psychology articles based on the theme being explored by the user. Offer a catalogue of validated tests without having to develop them yourself. University research. Leverage aggregated statistics in your work. Cross-reference the data with your own samples. Chatbots and AI assistants. Enrich your assistant's responses with verified psychological references. Guide users to tests suited to their situation. Content aggregators. Display the latest CBT psychology publications with structured metadata (title, category, reading time).Technical Specifications

In short: Psychology and Serenity offers a free REST API providing structured access to metadata from over 300 cognitive behavioral therapy articles, 25 validated psychological tests, and aggregated research statistics on topics including attachment styles, anxiety disorders, and depression. The API returns only metadata through three main endpoints: articles automatically categorized across 17 clinical themes with titles, descriptions, and URLs; tests with information on duration and question count across personality, anxiety, relationships, and neurodevelopmental categories; and research statistics from published studies with source citations. The service requires no authentication and implements rate limiting through response headers. Developers, researchers, and AI assistants can integrate this data to enhance mental health applications, support university research, enrich chatbot responses, and aggregate psychology content. The API specifically protects sensitive information by never exposing full article text, test questions, scoring algorithms, personal data, or medical diagnoses.
