JSON API Spec for openai apis?

Hey, is there somewhere or somehow I can get the openai apis in json so that I can plug them into the GPTs and Assistants easily? I can translate them with chatgpt but that seem wasteful, and still means a lot of copy and pasting as the openapi.yaml is huge.

Thanks!

Same problem here, I also see you did not get a response:

openapi: 3.0.1
info:
title: Assistants Listing API
version: 1.0.0
servers:

  • url: https://api.openai.com/v1
    paths:
    /assistants:
    get:
    summary: Returns a list of assistants
    operationId: listAssistants
    parameters:
    - name: limit
    in: query
    description: A limit on the number of objects to be returned, ranging between 1 and 100
    required: false
    schema:
    type: integer
    default: 20
    - name: order
    in: query
    description: Sort order by the created_at timestamp, ‘asc’ for ascending and ‘desc’ for descending
    required: false
    schema:
    type: string
    default: ‘desc’
    - name: after
    in: query
    description: A cursor for pagination to fetch the next page of the list
    required: false
    schema:
    type: string
    - name: before
    in: query
    description: A cursor for pagination to fetch the previous page of the list
    required: false
    schema:
    type: string
    responses:
    200:
    description: A list of assistant objects
    content:
    application/json:
    schema:
    type: object
    properties:
    object:
    type: string
    example: “list”
    data:
    type: array
    items:
    $ref: ‘#/components/schemas/Assistant’
    first_id:
    type: string
    last_id:
    type: string
    has_more:
    type: boolean
    components:
    schemas:
    Assistant:
    type: object
    properties:
    id:
    type: string
    object:
    type: string
    created_at:
    type: integer
    name:
    type: string
    description:
    type: string
    model:
    type: string
    instructions:
    type: string
    tools:
    type: array
    items:
    type: string
    file_ids:
    type: array
    items:
    type: string
    metadata:
    type: object

So I created this, which in theory should work… But the response is

So if you find a way please let me know. If I find a way I will let you know.

If I can figure out what is wrong it would be brilliant, as I want to convert every single call so that I can GPT it. But it fails on the basics, and search as I might, I do not find solutions. I got this to work on google, I even got aws functions working via api’s but this one… It is almost as if openai do not want tus to integrate openai into openai.

Is there an up to date JSON spec for the API in 2026 ?
