Datacircle - 2026 Pricing, Features, Reviews & Alternatives

Datacircle is a comprehensive, web-based directory and comparison tool for go-to-market (GTM) APIs, designed for sales, marketing, recruiting, and revenue operations teams evaluating data enrichment, prospecting, and lead generation API providers. The platform lists every available GTM API plan one row per plan per call, surfacing pricing per 1,000 results, not-found charges, rate limits, response speed, and fields returned, all without requiring an account or API key.

Datacircle covers 18+ GTM API categories including LinkedIn profiles, cached LinkedIn profiles, person enrichment, people search, email finding and validation, phone finding and validation, company profiles, company enrichment, company technologies, company hierarchy, company discovery, job postings, LinkedIn job search, SERP APIs, web search APIs, website visitor identification, and intent data. Each plan is scored across five weighted dimensions: price (40 points), data completeness (40 points), cost to get started (10 points), bundled calls (10 points), and performance (10 points), scaled to 100, giving buyers a structured benchmark for identifying best-value options by API type. The full dataset is downloadable as a single JSON or CSV file at no cost and with no sign-up required.

For teams integrating AI into their procurement or research workflows, Datacircle provides a SKILL.md file that instructs AI agents on how to download the dataset, interpret each key, and query it programmatically. An MCP server hosted at api.datacircle.dev/mcp is open to anyone with no key required and is compatible with Claude, ChatGPT, and Cursor, allowing AI assistants to query the GTM API dataset directly. Data is sourced from each provider's own pricing pages and documentation, supporting accurate, verifiable plan comparisons.
