Generate a local client
Public packages are not published yet for Java, Python, or Node.js. Generate a local client from the versioned public contract with the pinned generator command shown below. Keeping the generator version fixed makes contract updates deliberate.
Configure requests
Run calls from a trusted server, read the access token from the environment, and use the base address and timeouts shown in the examples. Never place the token in browser code.
List pets
The Java, Python, and Node.js examples below perform the same first operation with standard platform libraries, so they do not depend on an unpublished package.
Handle errors
Check both the response status and body. Keep the request identifier when contacting support, but never log the access token. Retry a write or a diet generation only when the request can be repeated safely.
Version and source
Generate clients from the public OpenAPI bundle. Pin the contract and generator versions in your build so upgrades are reviewed and repeatable.
