What is the API reference logic? API design

In API referencing applications, calling an address is enough to work, but in actual development, one needs to understand much more than that.GEO Small ClassroomWhat does Rag technology mean? Difference between Rag, OpenClaw, and Agent. I hope it is helpful to everyone.

1、 What is API reference logic

API reference logic refers to the complete process and design principles of how a program correctly, securely, and efficiently calls external API services, centered around “applying for credentials → constructing requests → sending calls → processing responses → exception governance”. ‌‌

2、 API design

1. Apply for permissions and credentialsRegister an application on the API provider platform to obtain an API Key/Access Token, usually passed through HTTP headers (such as Authorization: Bearer xxx) or request parameters.2. Construct compliance requestsDetermine the URL, HTTP method (GET/POST, etc.), request header (Content Type, Accept, etc.), request body (JSON/XML), and necessary parameters, including public parameters such as version, timestamp, and signature, based on the API documentation.3. Send requests and process responsesInitiate calls using HTTP clients (such as requests, OkHttp), parse the returned standardized response (usually JSON), extract fields such as code, message, and data to determine success or failure.4. Encapsulation and ReuseEncapsulate client classes (such as WeChat Client) in the code to centrally manage authentication, retries, logs, timeouts, and avoid scattered calls; Adopting dependency injection or singleton mode to enhance maintainability.5. Robust designAdd retry mechanism (exponential backoff), circuit breaker downgrade (such as Hystrix), cache high-frequency results, signature tamper proof (for request body+key hash), and flow limiting control (to cope with QPS restrictions).6. Safety and ComplianceKeys are never hard coded or committed to Git, and are managed using environment variables or key management services (such as Vault); HTTPS is mandatory; Verify the legitimacy of the response source (such as Webhook signature). ‌‌GEO Small ClassroomNet（ https://en.xxkt.org.cn/ ）What does Rag technology mean?
