54 Apis Terms

AI API
An application programming interface that exposes AI capabilities such as text generation, embeddings, classification, speech, or image processing to other...
AI Endpoint
A network-accessible endpoint through which clients send requests to an AI model or AI-powered service. AI endpoints often expose inference, embeddings,...
AI Rate Limit
A limit on how frequently AI requests can be made, often enforced per second, minute, account, or model. AI rate limits protect providers and shared systems,...
AI Request
A single call or interaction sent to an AI system for inference or processing. An AI request may include prompts, files, metadata, tools, or settings that...
API Client
A program, library, or component that sends requests to an API and handles the returned responses. API clients may be hand-written, generated from a...
API Design
The process of defining how an API should be structured, named, versioned, and behave so it is consistent, usable, and maintainable. Good API design balances...
API Documentation
Written reference material describing how to use an API, including endpoints, parameters, authentication, examples, response formats, and error behavior....
API Economy
The broader commercial landscape built around companies exposing services and data through APIs that others integrate into their own products. It covers...
API Endpoint
A specific network path or callable interface exposed by an API to perform an operation or access a resource. Endpoints are usually defined by a route plus...
API Error
A failure response returned by an API when a request cannot be processed because of validation issues, authorization problems, missing resources, rate limits,...
API Framework
A software framework used to build, route, validate, and manage APIs, often providing features like middleware, serialization, auth hooks, and schema handling....
API Hell
A miserable integration situation involving inconsistent APIs, poor docs, breaking changes, awkward auth, or conflicting conventions. In developer slang, API...
API Integration
The connection between two systems using an API so data or actions can flow between them reliably. API integrations often involve authentication, retries, data...
API Marketplace
A platform where API providers list, package, and sell or distribute API access to developers and businesses. It can simplify discovery, billing, and...
API Pagination
The technique an API uses to split large result sets into smaller pages, commonly through page numbers, offsets, cursors, or tokens. Pagination is important...
API Platform
A product or company whose primary value is exposing capabilities through APIs rather than only through an end-user interface. API platforms often compete on...
API Response
The data and status information returned by an API after it processes a request. A well-designed API response has a stable structure, clear semantics, and...
API Specification
A formal description of an API's operations, parameters, schemas, authentication, and expected responses, often written in a format such as OpenAPI. API...
API Specification Standard
A formal standard used to describe APIs consistently so tools, documentation, validation, and client generation can work across ecosystems. In open-source and...
API Testing
The practice of verifying that an API behaves correctly across success paths, edge cases, failures, authentication scenarios, and contract expectations. API...
API Token
A secret or signed token used to authenticate and authorize requests made to an API. API tokens vary in format and scope, but they commonly represent service...
API Wrapper
A library or module that wraps low-level API calls behind a more convenient interface, often handling auth, retries, pagination, and error translation for the...
Audio API
An application programming interface used to capture, process, generate, analyze, or play audio data. Audio APIs can expose low-level buffers and timing...
Backend Service
A server-side service that handles business logic, data access, integrations, or background processing for one or more clients or other services. Backend...
Backward Compatible
Describing a change that still works with older clients, data, integrations, or assumptions rather than forcing everything to upgrade at once. Backward...
Chat API
An API used to send, receive, stream, or manage chat messages, threads, participants, and related messaging features. Chat APIs are common in support tools,...
Client Library
A reusable library that helps an application interact with another service, protocol, or platform by abstracting requests, responses, retries, authentication,...
Cloud API
An API exposed by a cloud platform to manage resources such as compute, storage, networking, identity, or monitoring. Cloud APIs are the main interface for...
Cloud SDK
A software development kit that provides language-specific libraries and helpers for interacting with a cloud provider's APIs. Cloud SDKs handle...
Component Interface
The defined contract through which a component is used, including its inputs, outputs, methods, events, and expected lifecycle. A clean component interface...
Config Object
A structured object that groups related configuration values passed into a function, class, or component. Config objects make APIs easier to extend over time...
Create
To make a new resource, object, record, file, or instance exist in a system. In APIs and databases, create usually refers to the operation that inserts new...
Custom Serializer
A serializer implemented to convert data into a specific wire format, storage format, or schema with rules beyond the defaults. Custom serializers are useful...
Deprecated
Marked as outdated and discouraged for new use, even if it still works for backward compatibility. In practice it often means 'this will become your problem...
Escape Hatch
A supported way to bypass an abstraction, framework rule, or restrictive default when the standard path cannot handle a real requirement. Good escape hatches...
Foundation Model API
An API that exposes a large general-purpose model for downstream tasks such as chat, generation, embeddings, or tool use.
Function Calling AI
An AI setup where the model emits structured calls to external tools or APIs rather than only returning free-form text.
gRPC
A high-performance RPC framework based on Protocol Buffers, commonly used for typed service-to-service communication.
Headless Development
A development approach centered on backend systems that expose content or functionality through APIs without being tied to a single presentation layer. In...
JSON API
An application programming interface that sends and receives data encoded as JSON, typically over HTTP. In practice the term often implies REST-style endpoints...
JSON Everything
A joking critique of the tendency to serialize, configure, transport, and sometimes even think about every problem in JSON whether or not it is the right fit....
JSON Schema
A vocabulary for describing the structure, types, required fields, and constraints of JSON documents. It is used to validate payloads, generate forms or code,...
Magic String
A hardcoded string literal with special meaning that a program depends on, usually without type safety or strong discoverability. Magic strings make systems...
Message Format
The defined structure and encoding of data exchanged between systems, specifying field names, types, ordering, and serialization rules. Common message formats...
Metadata
Data that describes other data — such as a file's creation date, an image's resolution and EXIF tags, a database table's schema, or an API response's...
Model Endpoint
An API endpoint through which applications send requests to a specific model or model-backed service. Model endpoints often expose inference, embeddings,...
Moderation API
An API that classifies or flags content for safety, policy, or risk categories such as violence, self-harm, or harassment. Moderation APIs are often used as...

A data processing model in which data is produced, transmitted, and consumed incrementally as a continuous flow rather than as a single batch. In web APIs,...
Structured Output AI
An AI pattern where responses are constrained to a defined structure such as JSON, a schema, or typed fields.
