Questions
Is it free?
Yes. No key, no login, no usage fee. It is rate-limited to keep it fast for everyone.
What data does it return?
The same evidence-checked data as the website: 970 agencies across 24 countries, with tools, use cases, published prices and a 0–100 score. Every result links back to the public profile.
Does it store my conversations?
No. We only see the tool calls your assistant makes (for example a search query) and log them without personal data. request_intro stores the email you give it so we can make the introduction.
Which transport does it use?
Streamable HTTP (JSON-RPC over POST) at a single URL, protocol versions 2025-06-18, 2025-03-26 and 2024-11-05. No authentication.
