4A API - 2026 Pricing, Features, Reviews & Alternatives

FourA API is a web scraping API platform with integrated proxy infrastructure that enables data extraction at scale through a unified API interface. The software offers automated proxy rotation, anti-bot bypass capabilities and real-time monitoring to support data collection operations across various industries. It is designed for developers, data engineers and organizations that require reliable access to web data sources. The platform supports use cases such as price monitoring, market research, news sentiment analysis, odds extraction and regulatory compliance monitoring.

The platform includes a set of three distinct endpoints with varying levels of functionality. The single endpoint executes direct HTTP requests and provides the most cost-efficient option. The proxy finder endpoint evaluates proxy performance in real time and automatically selects the optimal proxy for each target. The browser endpoint delivers full browser rendering for pages with heavy scripting and returns rendered HTML, response headers and collected cookies. A credit-based consumption model applies to all endpoints and failed requests incur no charge. Proxy rotation employs a per-host success and failure rating mechanism and supports up to ninety automatic retries. Anti-bot bypass leverages real browser TLS fingerprinting for transparent passage through common bot detection systems. The API supports all standard HTTP methods and includes built-in response validation for status codes, headers and content.

The platform implements a Model Context Protocol server for integration with AI development environments such as Claude, Cursor, Visual Studio Code and Windsurf. Four tools enable developers to select direct requests, intelligent proxy routing or full browser extraction automatically. Integration requires minimal effort as the API functions with any standard HTTP client and is compatible with multiple programming languages. Authentication is managed through API key headers and requests are submitted as structured JSON payloads specifying the target location, HTTP method and optional parameters such as browser emulation settings.

The solution operates as a standalone service without native third-party software dependencies and can be embedded into custom applications and data pipelines. It maintains a record of high reliability and performance under continuous load and provides transparent insights into request processing. The infrastructure is maintained by an independent team based in Sofia and adheres to principles of transparency, operational stability and continuous improvement.
