Capabilities6 decomposed
deep research task execution
Medium confidenceThe Task API allows users to submit structured queries or existing data to perform deep research tasks, returning enriched outputs with confidence scores for each claim. This API employs advanced algorithms to ensure high accuracy and relevance in its responses.
Utilizes a unique confidence scoring system for claims, providing users with a quantifiable measure of reliability for the information returned.
Delivers more reliable and structured outputs compared to generic research APIs that lack confidence metrics.
web page content extraction
Medium confidenceThe Extract API accepts URLs and specified extraction objectives, returning either full page contents or compressed excerpts. This API is designed to efficiently parse web pages and deliver relevant information in a structured format, ideal for LLM integration.
Optimizes for LLM consumption by providing both full and compressed outputs, unlike many APIs that only return raw HTML.
More efficient in delivering structured content tailored for AI applications compared to standard web scraping tools.
real-time web monitoring
Medium confidenceThe Monitor API tracks specified web events and changes, returning updates when new events occur. This capability is designed for continuous monitoring and can be integrated into applications that require up-to-date information from the web.
Designed specifically for event tracking rather than general web scraping, providing structured updates tailored for agent consumption.
More focused on real-time updates compared to traditional web scraping solutions that lack monitoring capabilities.
interactive chat response generation
Medium confidenceThe Chat API processes user questions and returns responses in either free text or structured JSON format. This API is built to facilitate interactive applications, allowing for dynamic conversations with users while maintaining structured data outputs.
Combines the flexibility of free text responses with the rigor of structured outputs, making it suitable for both casual and formal interactions.
Offers a more structured approach to chat responses compared to traditional chatbots that typically return unstructured text.
entity matching and dataset creation
Medium confidenceThe Find All API generates structured datasets based on text queries, returning matches that meet specified criteria. This API is designed for users needing to create datasets from unstructured text inputs, making it easier to analyze and utilize data.
Focuses on transforming unstructured text into structured datasets, unlike many APIs that only provide raw search results.
More effective at creating usable datasets from text compared to standard search APIs that return unstructured results.
web search and extraction api for agents
Medium confidenceParallel provides a suite of APIs designed specifically for AI agents, enabling efficient web search and data extraction with structured outputs. Its capabilities are optimized for LLM consumption, making it ideal for applications requiring real-time, reliable web data.
Focused on providing structured outputs tailored for LLM consumption, unlike traditional search APIs that return raw data.
Offers superior structured outputs for agents compared to traditional search APIs, which often deliver unformatted results.
Capabilities are decomposed by AI analysis. Each maps to specific user intents and improves with match feedback.

About
Parallel Web Systems (founded by Parag Agrawal) builds web search and extraction APIs designed for agents rather than humans: the Search API returns ranked, extended webpage excerpts optimized for LLM consumption; the Task API runs deep research jobs with structured output and calibrated confidence ('Basis') for every claim. State-of-the-art results on deep-research benchmarks at lower cost than comparable stacks. Best for agents that need the live web as a reliable, citable data source — research pipelines, enrichment, monitoring. Limitation: usage-priced API only (no self-host); a young platform compared to incumbent search APIs.
