curl "https://api.insightsocial.app/v1/bluesky/search?query=espresso" \-H "x-api-key: $INSIGHTSOCIAL_API_KEY"
When to use it
Use it to find posts by keyword across all of Bluesky; use user/posts when you already know the account.
Parameters
Query parameters for GET /v1/bluesky/search. Send your key in the x-api-key header.
| Name | Required | Description |
|---|---|---|
| query | Yes | Search terms matched against post text. |
| sort | No | latest (newest first, the default) or top (Bluesky's own top ranking, which favours popular posts over recent ones). |
| since | No | Only posts written at or after this time. ISO 8601 date (2026-09-01) or datetime with a timezone (2026-09-01T00:00:00Z); any other shape is rejected with a free 400. |
| until | No | Only posts written before this time. Same format as since. Set it to the oldest published_at of your last call to fetch the next older batch; the boundary is compared to the second, so a post from that same second can repeat, and deduplicating on post.id removes it. |
| lang | No | Only posts tagged with this language, as a code such as en, ja or ko. |
| author | No | Only posts by this account: a handle such as espn.com or a did such as did:plc:.... An account that does not exist returns an empty list. |
Response fields
The same unified schema every platform returns, so code written for Bluesky works on the other eight. A field the platform did not provide is null and listed in unavailable.
| Field | Type | Notes |
|---|---|---|
| id | string | An identifier, always a string. Never parse it as a number: several platforms use ids above 2^53. |
| url | string | null | |
| kind | string | null | The format of the post. Format words only, never a platform name. short = short-form vertical video (a reel, a TikTok, a YouTube Short). |

Bluesky Search API: frequently asked questions
Send GET /v1/bluesky/search with the query parameter and your key in the x-api-key header. Returns Bluesky posts matching a keyword, up to 100 per page, each with its text, author, like/comment/share counts, and when it was written.
10 credits per successful call. A call that errors or finds nothing costs 0 credits, and an answer from the shared cache costs 2. Pro's 10,000 monthly credits cover about 1,000 calls at 10 credits each. Add dry_run=1 to see the price of a call without making it.
No. There is no Bluesky app, OAuth flow or app review. One InsightSocial API key works for this endpoint and every other platform, and your first 10 calls priced at 100 credits or less are free.
One call returns the posts in the data object of the standard response envelope. Fields the platform did not provide are listed in unavailable, so a null there means unknown, not zero.
You get an error or an empty result, and it costs 0 credits. The API reads public Bluesky data only, so private accounts and deleted content come back as not found rather than as partial data.
Yes. Add the hosted MCP server at https://api.insightsocial.app/mcp to your AI app and sign in. The assistant finds this endpoint by name, shows its price and calls it with your credits.
