GET /v1/lemmy/search_comments
What you get#
A list of Lemmy results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.
What it costs#
- Advanced · 5 credits for a fresh fetch, charged only when it succeeds.
- Free when served from cache (0.2 credit for a cached response over 100 KB).
- Free if the request is invalid (never charged) or the source fails or reports not found (refunded).
Parameters#
| Name | Type | Required | Default | What it is | Constraints |
|---|---|---|---|---|---|
instance | string | no | - | Known Lemmy instance (allowlisted), default lemmy.world | max 253 chars; must match [a-z0-9.-]{3,253}; trimmed, lowercased |
q | string | yes | (required) | Search query | max 200 chars; trimmed, repeated spaces collapsed |

Caching and freshness#
- Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
- Between 2 minutes and 15 minutes the cached copy is still served instantly and marked
stale: truewhile Onekey refreshes it in the background. - If the source is down when a refresh is needed, the last copy can be served for up to 1 hour more (marked stale).
- A "not found" is remembered for 1 minute and is free.
- The cache is shared across all customers, which is what keeps repeat calls cheap.
What can go wrong#
| Status | Code | What to do |
