+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# OpenAPI Petstore
+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+This Motoko client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.

+
+## Installation
+
+This is a Motoko module that can be used in your Internet Computer project.
+
+## Usage
+
+Import the generated API modules in your Motoko code:
+
+```motoko
+import SomeApi "mo:petstore-client-nodfx/Apis/SomeApi";
+// or using destructuring for specific functions
+import { someFunction } "mo:petstore-client-nodfx/Apis/SomeApi";
+```
+
+Configure and call the API:
+
+```motoko
+import { defaultConfig } "mo:petstore-client-nodfx/Config";
+
+// Use the default config as-is, or customize specific fields:
+let config = { defaultConfig with auth = ?#bearer "my-token" };
+
+let result = await* SomeApi.someFunction(config, ...);
+```
+
+The `defaultConfig` has `baseUrl` pre-set to the API's base URL, `cycles = 30_000_000_000`, and all optional fields set to `null`.
+
+Alternatively, use the suite-based API to bind config once and call multiple functions without threading it through each call:
+
+```motoko
+import { SomeApi } "mo:petstore-client-nodfx/Apis/SomeApi";
+
+let api = SomeApi(config);
+let result = await api.someFunction(...);
+let other = await api.anotherFunction(...);
+```
+
+### HTTP Outcalls and Cycles
+
+The generated API client makes HTTP outcalls using the Internet Computer's management canister. HTTP outcalls require cycles to execute.
+
+**Important:** Before calling any API endpoints, ensure your canister has sufficient cycles:
+
+For local development:
+```bash
+# Get your canister ID
+CANISTER_ID=$(dfx canister id your_canister_name)
+
+# Add cycles (100 trillion cycles for testing)
+dfx ledger fabricate-cycles --canister "$CANISTER_ID" --amount 100000000000000
+```
+
+For production deployment, you'll need to fund your canister with cycles through the NNS or cycles wallet.
+
+Each HTTP outcall typically costs around 20-50 million cycles depending on the request/response size.
