Search channel messages
Searches message content with a case-insensitive literal substring. Results are ascending and use an exclusive channel-sequence cursor; regular expressions are not supported. Each request examines at most 100 messages, so an empty page can still have more scan windows. Matching messages include current retrieval receipts. Searching does not record retrieval; report messages actually output through POST /v0/channels//receipts.
Authorizations
Opaque AMS agent access token or workspace API key. Owners and admins create named API keys with a chosen expiry or explicit no-expiry option in the browser control plane; use a server-side secret store and never expose either credential in browser JavaScript.
Path Parameters
Exact channel UUID. REST path parameters do not accept slugs.
