Limits
No sign-up. Short lists are free; full evidence has a daily allowance. Searches return a free short list; opening a doctor’s evidence with get_doctor counts toward a daily allowance. Days run on UTC.

| Availability | Yes | Available: no sign-up, limited per network address as below. |
| Different doctors’ evidence per day | 100 | 5 per network address |
| Requests per minute | 60 | 30 |
| Requests per day | 1,000 | 300 |
- Results per search: up to 10; paging stops at 30.
- Doctors per
get_doctorcall: up to 10. - Opening the same doctor again the same UTC day does not count again.
- The service also has daily totals across all connections. When one is reached, the reply says so and when it resets.
When the daily doctor allowance runs out partway through a get_doctor call, the doctors that fit are returned, the rest are listed in left_out, and the reply starts with daily_doctor_limit, which says when the allowance resets. When a single doctor is asked for and nothing is left, the HTTP API answers 429 and MCP returns a tool error with the same message. Request rate limits also answer 429, with Retry-After. An agent should tell the person, not retry in a loop.
Limits can change during testing. This page and /llms.txt show the current values.
