Serpstack

Through its real-time Google SERP data service, Serpstack provides developers with comprehensive access to search engine results across multiple categories and formats. As a product of apilayer's suite of developer tools, this API offers detailed capabilities for integrating comprehensive search functionality into various applications.

About Serpstack

Serpstack is built and maintained by apilayer, a company behind popular developer tools and APIs including currencylayer, eversign, and invoicely. The service provides real-time Google SERP data through simple HTTP GET requests with JSON or CSV responses, supported by extensive documentation across multiple programming languages. Each user receives a unique API access key for authentication via HTTPS (256-bit encryption), with support for all major browsers and devices worldwide. The API handles nearly 100% of Google's search result types, including web, image, video, news, shopping, and local results, using a powerful proxy network and proprietary scraping technology.

API Fundamentals

The API structure follows a simple HTTP GET request format, with results delivered in lightweight JSON or CSV formats for easy integration into existing workflows. Each request requires an access_key, which serves as authentication and must be securely managed by users.

The request URL takes the form: https://api.serpstack.com/search?access\_key=YOUR\_ACCESS\_KEY

Response Format and Data Handling

Results are encapsulated in a JSON object, with detailed error handling built into the API response. Common error codes include 404 for non-existent resources, 403 for missing or invalid access keys, and 429 for rate limit exceedance. Each response includes metadata such as the total number of results, processing time, and the exact query string used.

The API supports a rich array of parameters for refining search queries, including location targeting, device preference, and result type specification. All requests are processed through a powerful proxy network designed to handle global IP ranges and browser clusters efficiently.

Plan-Specific Features

Basic Plan users receive 5,000 monthly searches with access to full functionality, while Business and Business Pro plans scale up to 20,000 and 50,000 searches respectively, with additional search charges applied beyond these limits. All subscription tiers benefit from 24/7 technical support and access to the company's proprietary web scraping infrastructure.

Support and Billing Options

Users can manage their subscription through the company's billing portal, with flexible options for monthly or yearly payments. Annual subscriptions offer a 15% discount, while downgrades require a full billing cycle before taking effect. The company provides automatic notifications when approaching usage limits, helping users manage their API quotas proactively.

All support levels provide access to regular product updates, dedicated account teams, and priority bug review processes.
