Import into Postman

You can import the Valyu OpenAPI spec directly into Postman to test all endpoints interactively.
Importing the Valyu OpenAPI spec into Postman
1

Copy the spec URL

Copy this URL: https://docs.valyu.ai/api-reference/openapi.json
2

Open Postman and import

In Postman, click Import and paste the URL. Postman will generate a complete collection with all Valyu endpoints.
3

Add your API key

Set the x-api-key header to your API key in the collection variables. Valyu authenticates with the x-api-key header on every request - not a Bearer token.
Every request authenticates with the x-api-key header. This also works with other API tools like Insomnia, Bruno, and HTTPie - any tool that supports OpenAPI 3.0 imports can use this spec.
