Reference
Exact contracts for every Capxul surface, one page per operation.
Reference pages answer one question: what exactly does this call take, and what does it give back. Start with a tutorial if you are new, and come here when you need the precise shape.
CLI
Every capxul command, its flags, what it returns and how it fails.
Core SDK
@capxul/sdk: the typed client for browsers, Node services, scripts and agents.
Core SDK API
Every public method, grouped by what it works on, with its result and errors.
React SDK
@capxul/sdk-react: the provider, query and mutation projection of the client.
Hooks
One page per React hook, with the client method it wraps.
Error codes
What each code means and how to fix it.
Contract addresses
Every contract, in each environment.
The CLI, error code and contract address pages are generated from the code, so they match the release you run.
How to read a reference page
- Usage shows the call with every option.
- Example shows the same call in each surface you can use. Pick a tab once and the site remembers it.
- Returns shows what comes back, including the fields you will branch on.
- Errors lists every refusal code the call can return. Branch on the code, not on the message.
