What it does
The Datacircle API compares the pricing plans of go-to-market (GTM) data APIs, such as email finders, email verification, phone lookup, company and person enrichment and LinkedIn data, with a score for price, accuracy and speed, for example to pick the cheapest email verification API. Requests are GET calls that answer in JSON, and the whole sheet can also be downloaded as one JSON file. Free, no key needed, at up to 60 calls a minute from one IP address. The data is under CC BY 4.0, so credit Datacircle. An official MCP server at https://api.datacircle.dev/mcp lets AI agents search the plans.
