What is Nascentist?

Nascentist is a coding-focused AI API designed for software workflows. It can complete code, reason about bugs, and produce actionable outputs suited to development teams. The API surface is intentionally compact: one-shot completion endpoints for speed and agentic endpoints for iterative fixing and review tasks.

What makes it different is workflow design. Instead of only generating plausible text, agentic paths are built for real debugging loops where outputs need to be checked, refined, and returned in a form your product can use.

Authentication Overview

Every request must include a Bearer API key in the Authorization header. Generate keys from Dashboard → API Keys and keep them server-side only.

Response Format

JSON responses include stable metadata fields such as id, model, and usage. Error responses use a consistent error object to simplify retries and alerting.
