Pythia API is 📝CulturePulse's proprietary AI ontology and 📝text-analysis engine, exposed via API, that scores words, phrases, and concepts against a lexical-frequency cultural ontology spanning 93 psychological and cultural dimensions across 100+ languages.
Pythia is a lexical frequency-based cultural ontology in which words, phrases, and concepts are coded by their relationship to categories of human culture and psychology. The ontology spans 93 psychological and cultural dimensions, and every dimension returns an independent numerical score from the API. The system additionally classifies text against five ontological categories — artifact, natural, person, plant, and animal — and a set of meta-ontological categories such as knowledge, belief, action, and institution, and it can report how much of a given text it actually understands.
The API returns dimension scores across groups including morality, gender, temporal, linguistic, social, perception, biology, interest, psychology, speech, and personality, retrievable individually or all together in a single call. Inputs are either raw text or pre-built 📝digital twins — audience profiles constructed from uploaded data files. A resonance endpoint scores similarity between inputs, returning both a raw 0–1 value and a rescaled 0–100 value for direct decision-making. Two algorithms operate independently of the ontology: a readability measure based on the LIX calculation (Björnsson, 1971) and a Shannon information-entropy measure (Shannon, 1948), the latter usable on a single text or a batch average. The methodology has appeared in blind peer-reviewed research, including Lane et al. (2023).
Authentication exchanges a client_id and client_secret for a bearer token valid for seven days, sent as an Authorization: Bearer header on all requests against the base URL https://api.culturepulse.ai; interactive documentation is served at /docs. Clients also receive credentials for a dashboard at dashboard.api.culturepulse.ai to monitor API usage and manage team access. Pythia is also distributed via the AWS Marketplace.
