Issue with response_format not being respected in Chat Completion API

[kinesra75]

Hi everyone,

I'm using the Chat Completion API and trying to enforce a specific response_format by injecting a json_schema into my payload. However, despite specifying the schema, the API continues to return responses in Markdown format. Below is an example of the payload I'm sending:

{
"model": "sonar",
"messages": [
{
"role": "system",
"content": "Act as a tour guide"
},
{
"role": "user",
"content": "Can you give me the best restaurant in Paris?"
}
],
"response_format": {
"type": "json_schema",
"json_schema": {
"schema": {
"type": "object",
"properties": {
"restaurantName": { "type": "string" },
"restaurantPrice": { "type": "string" },
"restaurantUserRating": { "type": "string" },
"restaurantAddress": { "type": "string" },
"restaurantArea": { "type": "string" },
"restaurantType": {
"type": "string",
"enum": ["thai", "french", "african"]
},
"restaurantCuisine": { "type": "string" },
"restaurantDescription": { "type": "string" }
}
}
}
},
"temperature": 0.7
}

The API consistently returns responses in Markdown format rather than adhering to the provided JSON schema.
I expected the API to generate a JSON response formatted according to the schema I defined.

Is the response_format parameter with a json_schema type supported in the API?
If it is supported, am I using the correct syntax for the payload?
Are there any additional steps or settings I need to configure to ensure the schema is respected?
Any guidance on this issue would be greatly appreciated.

Thank you!

Are you tier 3 in the API? The structured outputs are only supported if you are tier 3, meaning you need to have spent at least $500 (all time) on the API.

So what does this all time mean ?
so what i can understand is by this term all time is the credit we have spend for all previous fro day we go the perplexity api ?
For example : i started using api a year back does that mean the total money in this year ?
