What relays_searchRegistrarDomains does on Genesis
AI agents call relays_searchRegistrarDomains to retrieve information from Genesis without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
q | string | Yes | Name to search, at least 2 characters; the part before the first dot is used |
tlds | string | — | Up to 10 comma-separated TLDs, default com,net,org,io,dev,ai,co,app |
suggestions | boolean | — | true returns available variations of the name instead of per-TLD results |
Parameters from the server's own tool schema.
Why relays_searchRegistrarDomains is rated Low
Even though relays_searchRegistrarDomains only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
