Serpent API

Serpent API covers SERP retrieval, AI citation tracking, and social media scraping through a single API key without monthly subscription. While documentation depth may vary across newer endpoints, teams needing search data across multiple search engines, and four major LLMs can access all of it without managing separate provider accounts.

What Is Serpent API?

Serpent API is a pay-as-you-go search data platform covering Search Engine Results Page (SERP) retrieval across Google, Bing, Yahoo, and DuckDuckGo, AI citation tracking across ChatGPT, Claude, Gemini, and Perplexity, and social media scraping for YouTube and Instagram. This is all done through a single API key with standardized JSON responses. Every endpoint returns structured data, including organic results, People Also Ask, AI Overviews, featured snippets, ads, shopping listings, and video results, depending on the engine queried.

What Is Serpent API Best For?

Serpent API is best known for its AI Rank Tracking API, which queries ChatGPT, Claude, Gemini, and Perplexity in a single API call and returns structured citation data. This includes citation URLs, cited text, rank position, and a composite visibility score from 0 to 100 across all four Large Language Models (LLMs) simultaneously. The visibility score is calculated from four factors: citation presence, citation position, citation frequency, and source authority.

How Much Does Serpent API Cost?

Pricing starts at $10 the Default plan. Every new account receives 10 free Google SERP searches to try the platform before purchasing credits. Serpent API uses a pay-as-you-go pricing model with no subscriptions or recurring charges. Other plans include:

How Does Serpent API Work?

Getting started with Serpent API requires three steps:

• Create an account. If you sign up with Google, you'll receive 10 free web searches instantly with no credit card required
• Generate an API key from the dashboard with one click
• Send a GET request to the relevant endpoint with your query and API key in the request header. Responses return in structured JSON

Depending on the data type needed:

• For SERP data, pass the search query, engine, and optional parameters (country, language, page number, result type) to the /api/search endpoint
• For AI citation tracking, pass a keyword and optional brand domain and specify which LLMs to query. The API routes requests to each engine in parallel and returns normalized citation data
• For pixel-level SERP geometry, add pixel_position=true to any search call to receive the y-coordinate and full bounding box of every element on the SERP at no additional cost

Serpent API Use Cases

Our analysis of Serpent API's current capabilities has helped us identify several scenarios where the platform is a strong fit:

1. SEO Agencies Tracking Competitor Rankings Across Multiple Engines

Agencies managing keyword portfolios for multiple clients often need daily SERP snapshots across Google, Bing, and other engines without committing to a monthly subscription that scales poorly with client volume. Serpent API's pay-as-you-go pricing across four engines under one API key lets agencies pull data only when needed, and switch engines per request using a single parameter.

2. SaaS Teams Building Rank Tracking Or Keyword Research Products

Development teams building SEO tools that require SERP data as a backend dependency need a reliable, structured data source they can embed in a product without exposing their margins to per-seat subscription pricing. Serpent API's flat per-call pricing and consistent JSON response shape across all four engines make it suited to teams building internal or external SEO dashboards where query volume is predictable, and cost needs to scale linearly.

3. Brand And Marketing Teams Monitoring AI Citation Presence

As AI-generated answers from ChatGPT, Claude, Gemini, and Perplexity increasingly influence how users discover brands, teams need a way to track when and how those models cite their domain. Serpent API's AI Ranking endpoint queries all four LLMs simultaneously and returns a composite visibility score from 0 to 100, calculated from citation presence, position, frequency, and source authority, giving teams a single metric to track over time.

4. Data Engineers Feeding Real-Time SERP Data Into LLM Pipelines

Engineers building AI agents, research tools, or content pipelines that require live web search results often need a lightweight API that returns clean JSON without requiring browser automation or scraper maintenance. Serpent API handles proxy rotation, anti-bot evasion, and retry logic on the backend, delivering structured SERP results via a single GET request for Google and DuckDuckGo.

Is Serpent API Right For You?

If your team needs SERP data at volume — keyword rank tracking, AI citation monitoring, competitor research, or search data pipelines — and has been paying $5–$50 per 1,000 searches under a monthly subscription, Serpent API's deposit-based pricing is worth evaluating. Built by Contentladder Marketing Private Limited, a digital marketing and AI search optimization agency, the platform has served over 1,000,000 API calls and supports 100+ country codes across all four engines. It is available to any developer immediately on sign-up.
