Datacircle, a price sheet and benchmark for GTM APIs
Datacircle is a price sheet of GTM APIs: data for sales, marketing and lead generation, such as people and company records, social media, ecommerce and reviews. Each row is one plan of one vendor's API, with its price per 1,000 results, what a call with no result costs, rate limits, speed and the fields it returns. Datacircle also sends the same sample inputs to each vendor's real API and scores the plans on the results, best first.
What Datacircle offers
The details below come from the Datacircle website, its FAQ and its docs, read on November 4, 2026. Check Datacircle's site for the current version.
| Item | What Datacircle states |
|---|---|
| What it lists | Every GTM API it finds, one row per plan: price per 1,000 results, price of a call with no result, rate limits, speed and fields |
| How it scores | Out of 100: price 40, accuracy 40, cost to get started 10, other calls the same budget pays for 10, performance 10; accuracy and performance come from Datacircle's own benchmark |
| How it tests | The same inputs (for example 20 Xiaohongshu notes) go to every vendor on the same day; accuracy is the share of each record a vendor returns, and a plan tested on fewer inputs scores lower |
| Where the numbers come from | Each vendor's own pricing page and docs, plus what vendors tell Datacircle; the CSV lists the page behind each row |
| How to get the data | The web sheet, or the whole sheet as CSV or JSON with no sign-up; a free MCP server at api.datacircle.dev/mcp and a SKILL.md for AI agents |
| Cost | Being on the sheet is free; Datacircle says it is open to talk about more by email |
Each plan has its own page with an llms.txt, linking to the vendor's site and API docs. Ranking pages give the test date, the number of inputs and each part of every score, so you can check the result.
Who it is for
- Teams buying data APIs: compare price per 1,000, fields and benchmark scores in one sheet instead of reading each pricing page.
- AI agents choosing an API: connect Datacircle's MCP server or SKILL.md and ask for "the cheapest plan of this API" or "every plan of this vendor".
- Data API vendors: send your pricing page and docs to Datacircle to be listed; buyers compare on the sheet and click through to your site.
EveryInfra on Datacircle
EveryInfra's APIs are on Datacircle (67 APIs on November 4, 2026). Each one has a page with the price per 1,000 results for every top-up tier, for example the Zhihu profile API. Every EveryInfra platform uses one call, POST /api/v1/social, and failed or empty calls are not charged. See pricing and the docs.
Datacircle is benchmarking three EveryInfra APIs: Xiaohongshu note details and profiles, and Facebook user posts. The scores are the ones Datacircle publishes.
