Zod schema or JSONSchema object to convert

SchemaInput | undefined

Returns

Record<string, any> | undefined

JSON Schema object that can be sent to LLM providers

Example

typescript

import { z } from 'zod';

// Using Zod schema
const zodSchema = z.object({
  location: z.string().describe('City name'),
  unit: z.enum(['celsius', 'fahrenheit']).optional()
});

const jsonSchema = convertZodToJsonSchema(zodSchema);
// Returns:
// {
//   type: 'object',
//   properties: {
//     location: { type: 'string', description: 'City name' },
//     unit: { type: 'string', enum: ['celsius', 'fahrenheit'] }
//   },
//   required: ['location']
// }

// Using JSONSchema directly (passes through unchanged)
const rawSchema = {
  type: 'object',
  properties: { location: { type: 'string' } },
  required: ['location']
};
const result = convertZodToJsonSchema(rawSchema);
// Returns the same object

import { z } from 'zod';

// Using Zod schema
const zodSchema = z.object({
  location: z.string().describe('City name'),
  unit: z.enum(['celsius', 'fahrenheit']).optional()
});

const jsonSchema = convertZodToJsonSchema(zodSchema);
// Returns:
// {
//   type: 'object',
//   properties: {
//     location: { type: 'string', description: 'City name' },
//     unit: { type: 'string', enum: ['celsius', 'fahrenheit'] }
//   },
//   required: ['location']
// }

// Using JSONSchema directly (passes through unchanged)
const rawSchema = {
  type: 'object',
  properties: { location: { type: 'string' } },
  required: ['location']
};
const result = convertZodToJsonSchema(rawSchema);
// Returns the same object
