}Generate code from a natural language prompt. The Theo Code engine is optimized for production-quality code and long-form output.
Authentication
Requires a Bearer token. See Authentication.Request Body
string
required
Description of the code to generate.
string
Target programming language (e.g.,
"typescript", "python", "go", "rust"). Appended as a hint to the engine.string
Target framework (e.g.,
"express", "nextjs", "fastapi", "gin"). Appended as a hint to the engine.Request Examples
curl -X POST https://www.hitheo.ai/api/v1/code \

console.log(res.content); // Generated code
console.log(res.artifacts); // Any files created
Response
string
Unique code generation ID (prefixed
code_).string
ISO 8601 timestamp.
string
