# Prism Voice API (https://www.socialcrawl.dev/platforms/prism/voice)

> Fetches a handle's recent posts from four microblogs in parallel, time-merges them into one chronological feed, and computes platform presence, a cross-post rate, and a per-platform tone label (a soft `gpt-5.4-nano` heuristic that degrades to absent on failure). Microblogs the handle isn't on return empty arrays with `platform_presence:false` — the absence map is the product. Flat 5cr; all-miss → full refund. The `legs[]` block reports each leg's status, cost, and latency. v1 is list-level (no per-post detail drill).

TL;DR: `GET /v1/prism/voice` costs 5 credits per call and returns SocialCrawl's unified JSON schema. Single x-api-key auth, 100 free credits on signup.

## Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| `handle` | yes | The handle to look up across all four microblogs (a single leading @ is stripped). |
| `platforms` | no | CSV subset of twitter,threads,bluesky,truthsocial (default all four). |
| `cursor` | no | Opaque per-platform pagination token from a prior response's cursors_by_platform (twitter is a single non-paginatable page). |
| `include` | no | CSV subset of posts_by_platform,merged_timeline,computed to trim the payload (posts_by_platform is always returned). |

## Code example

```bash
curl "https://www.socialcrawl.dev/v1/prism/voice?handle=nasa" \
  -H "x-api-key: sc_YOUR_API_KEY"
```

## FAQ

### What is the SocialCrawl Truth Social API (Prism Voice)?

The Truth Social API endpoint GET /v1/prism/voice takes one handle and pulls that person's recent public posts from four microblogs — X, Threads, Bluesky, and Truth Social — in parallel. It time-merges them into one chronological feed and adds platform presence, cross-post rate, and a per-platform tone label.

### Which platforms does the voice endpoint cover?

Four microblogs: X (Twitter), Threads, Bluesky, and Truth Social. Pass the platforms parameter to scope down — for example platforms=twitter,truthsocial. A handle the person isn't on returns an empty array and platform_presence=false, which is a valid answer, not an error.

### How much does a Prism Voice call cost?

Each call is a flat 5 credits, covering all four microblog legs plus the time-merge and tone analysis. New accounts get 100 free credits with no credit card. If the handle is on zero of the four platforms, the call returns no data and the 5 credits are refunded in full.

### What is cross_post_rate in the voice response?

It is the fraction of a person's posts that appear near-duplicated on another platform within a short time window, computed by text similarity — no LLM. A high cross-post rate means they broadcast the same message everywhere; a low rate means they tailor each audience differently.

### Why track one person's voice across X, Threads, Bluesky, and Truth Social?

Executives, founders, and politicians increasingly post differently to different audiences — measured on X, combative on Truth Social. Voice surfaces that divergence in one call. No other API time-merges all four microblogs, which makes it built for comms risk, founder-signal, and accountability work.

### Do I need to send the platform with the handle?

No. The handle parameter is the only required input, and one leading @ is stripped automatically. Voice queries all four microblogs with the same handle, so you do not map handles per platform — the platform_presence map tells you which of the four the person actually posts on.
