# Prism (/docs/prism)

Cross-platform composites, one call fans out to many sources and returns one merged, computed answer

A Prism endpoint is a **composite**: one call fans out to several platforms in parallel, merges the results, and returns a single computed answer. You do not orchestrate the fan-out, the retries, or the merge yourself.

Base URL: `/v1/prism/...`

  Every number a Prism composite returns is **computed in code, not generated by
  a model**. Where a composite does use an LLM (topic clustering, tone labels),
  it narrates data that was already computed deterministically.

## What a composite is

A normal endpoint reads one thing from one source. A composite answers a question that no single source can answer, by calling several of them and doing the reconciliation work in between.

Three properties follow from that, and all three change how you write the client:

1. **A composite has legs, and a leg can fail without failing your call.** Responses carry a coverage signal (`legs[]`, `sources_succeeded`, `coverage`, or a `confidence` block, depending on the composite) telling you which sources answered. Read it before you read the numbers.
2. **A composite is priced per call, not per leg.** The price does not go up because a source was slow or a fan-out went wide, except where the request shape itself sets the width.
3. **A composite returns the same unified schema as its parts.** A profile inside a composite response is byte-identical to the same profile from its native endpoint, so one parser handles both.

## When to use a composite instead of N calls

Reach for a composite when the answer needs cross-source reconciliation and you would otherwise write it yourself: deduplication across platforms, weighting one source against another, matching the same entity under two different ids, or holding a fan-out open while slow legs settle.

Stay on the per-platform endpoints when you want one source's raw data, when you need a field the composite does not surface, or when you are refreshing something you already hold. `prism/lookup` and `prism/post-stats` exist precisely for that last case and are priced accordingly.

## How Prism is priced

Composites come in three pricing shapes.

| Shape             | How it works                                                                                                            | Examples                                                                                                                                             |
| ----------------- | ----------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Flat**          | One price per call regardless of how many legs run                                                                      | `reputation` (30), `brand-mentions` (50), `leads` (50), `campaign` (35), `crisis-postmortem` (35), `answers` (15)                                    |
| **Param-derived** | The price is fixed by the request shape, so you can compute it before you call                                          | `handle-audit` and `creator-card` (5 for up to 4 platforms, +1 per extra); `share-of-voice` per brand; `org-radar` per repo; `app-reviews` per store |
| **Metered**       | A ceiling is held upfront and the unused portion is refunded, because the work depends on what the data turns out to be | `comments` (2-200), `ai-visibility` (2 per probe), and the three `POST` bulk endpoints                                                               |

The bulk endpoints are metered **per item at each row's own platform rate**, so a 50-handle `profiles` batch of TikTok handles is 50 credits while the same batch of LinkedIn handles is 250. Only successful rows are charged.

Quote ranges rather than floors when you budget: the roster below shows each composite's base tier price, which is the bottom of the range for the metered and param-derived ones.

For `handle-audit`, a public response-cache hit costs 0 credits. A non-200 execution failure after deduction receives a full refund, and request-validation errors happen before billing. If every leg fails, the whole call is refunded. Every successful HTTP 200 receives the full request-shaped charge even with partial evidence, and there is no partial refund on that path.

## Quickstart

### 1. Pick a composite by the question you are answering

Each composite answers one question end to end. `handle-audit` answers "is this handle worth pulling"; `comments` answers "what did everyone say on this post"; `reputation` answers "how is this brand seen across review sites".

### 2. Make the call

```bash title="cURL"
curl "https://www.socialcrawl.dev/v1/prism/handle-audit?handle=mrbeast" \
  -H "x-api-key: YOUR_API_KEY"
```

### 3. Read the coverage block before the numbers

A composite is a fan-out, so check which sources answered before you act on the result. `handle-audit` returns score-v2 evidence, nullable scores, component coverage, surface estimates, and leg diagnostics.

### 4. Read computed fields

Direct post and author endpoints inside a composite response may include the shared computed fields such as `engagement_rate`, `language`, and `content_category`. See [Computed fields](/docs/computed-fields.md) for formulas and null semantics.

`share-of-voice` is 20 credits per brand web-only and 40 per brand with social (the default), so the price is fixed by how many brands you pass and whether `include` contains `social`. Pass `competitor` to `earned-media` to see which outlets covered them and not you.

`handle-audit` and `creator-card` are 5 credits for up to 4 platforms and +1 per extra. Run `handle-audit` before you spend on the pull.

`product-reviews` tells you what buyers said. `review-integrity` tells you whether to trust the stars. `app-reviews` covers review text. `apps-lookup` compares the listings, and its title-match guard is what stops two apps sharing a name from being merged.

`launch-echo` is the single-moment view; `devtool-pulse` is the standing one. `org-radar` is 1 credit base plus 5 per repo expanded, up to 10 repos. Set `repos` to control it.

A probe on `ai-visibility` is one prompt times one run times one engine, so a 5-prompt, 3-run, 2-engine sweep is 60 credits. The ceiling across the widest possible sweep is 1605, so set `prompts`, `runs` and `engines` deliberately, or use `preset=quick|standard|deep`, which sets `runs` and caps `prompts` for a flat probe budget. The engines are Perplexity Sonar and Grok, and appearance is detected deterministically via recognition tokens rather than by a model's judgement. Add `include=web_baseline` to see which AI-cited domains you do not yet rank on. No per-platform endpoint covers this.

Truth Social has no search, so `truthsocial-pulse` is the way to watch an account without chaining calls. On `korea-gap` the social leg is the default. Drop `social` from `include` if you only need the web comparison.

`lookup` sniffs the platform and resource, dispatches, and adds no surcharge: a social post routes to 1 credit, an Amazon product to 5. It takes ITEM links only, so a profile, channel or storefront URL is a free 400 pointing you at that platform's own `/profile` endpoint. The `resolved` block names the platform, endpoint, and archetype so an agent knows the shape that follows.

`post-stats` and `profiles` bill 1 credit on most platforms and 5 for Instagram and LinkedIn. Dead, errored, and unsupported URLs are refunded and never fail a `post-stats` batch, and only successful rows are charged on `profiles`. `profiles` supports instagram, tiktok, youtube, twitter, threads, twitch, snapchat, truthsocial, bluesky, kwai, linkedin, and facebook. That roster is this endpoint's own, and is unrelated to the universal-search fan-out.

`comment-lookup` takes each item as either `{ comment_url }` or `{ platform, post_url, comment_id }`, bills TikTok at 2 and Instagram at 5 (more with `deep_scan`), and holds at most 100 credits for the whole batch. Store each row's `lookup.position_hint` and pass it back next run to keep a daily refresh near the floor.

```bash title="cURL"

# Refresh engagement on a batch of posts

```

  `prism/comments` is the one composite whose cost is genuinely unbounded by
  your request shape. It pages a thread to completion and bills per page, from
  **2 up to 200 credits on a single call**. A post with tens of thousands of
  replies will spend the whole budget. Cap it with `max` or `limit` before you
  point it at a viral thread.

## All endpoints

  Five more cross-platform composites live outside the `/v1/prism/...` namespace
  because they belong to a single source's vocabulary: `/v1/search/everywhere`,
  `/v1/search/news`, `/v1/search/forums`, `/v1/reddit/omni-search`, and
  `/v1/naver/brief`, as does the per-platform `/v1/{platform}/profile/full`.
  They behave like composites and are priced like them. They are just not on
  this page's roster.

## Platform notes

- **Composites use `GET` with query parameters**, except the bulk endpoints (`post-stats`, `profiles`, `comment-lookup`), which take a `POST` JSON body.
- **Several composites take an `include` CSV that switches optional legs on or off.** On `share-of-voice`, `korea-gap`, `creator-vet` and `video-intel` that CSV also moves the price, so read it as a cost control rather than a display flag.
- **Long-running composites can stream Server-Sent Events** when you send `Accept: text/event-stream`, emitting each leg as it settles. This is the right mode for the 30-credit-and-up composites, which do real fan-out work before they answer.
- **A leg can fail without failing your call.** Read the coverage signal before the numbers.
- Responses follow the unified SocialCrawl schema, so a profile returned by a composite is byte-identical to the same profile from its native endpoint.
