## Interactive JSON-RPC API reference

The Conduit Nodes documentation now includes an interactive JSON-RPC API reference and method playground, generated from Conduit's OpenRPC specification with Fern's OpenRPC support.

* **Explore supported methods** -- Browse the Conduit Nodes JSON-RPC API by method, with descriptions, parameters, response schemas, and examples in one place.
* **Try requests in the playground** -- Build JSON-RPC requests from the documented schemas and test them against your Conduit endpoint.
* **See method pricing** -- Each method displays its Compute Unit cost so you can understand request cost while integrating.
* **Use a machine-readable specification** -- The same OpenRPC source powers the reference, keeping the public API specification and rendered documentation aligned.
