# FactCheck Claims

The inaccurate claims behind your accuracy score — the false statements AI
answers made about your category, from the platform's FactCheck tab. Returns a
flat, paginated list, or `group_by` one dimension to section them. A claim is
`{ cluster_id, claim, occurrence }` plus whatever `include` adds.

* **`occurrence`:** the % of scoped responses that carry the claim.
* **`include`:** any of `theme`, `reasoning`, `models`, `evidence`, `citation_sources`.
  * `models[]` — which models make the claim: `{ id, name, occurrence }`.
  * `evidence[]` — refuting knowledge-base snippets: `{ id, kb_path, kb_snippet, source_updated_at }`.
  * `citation_sources[]` — the cited pages driving the claim: `{ href, hostname, citation_category, domain_category, snippet, citation_share }`. `citation_share` is a percentage, model-balanced, matching the Citations tab.
* **`group_by`:** 0 or 1 of `model`, `region`, `persona`, `prompt`, `topic`, `tag`, `theme` (no `citation` or `date` — those are scores dimensions). Empty → one flat paginated list; a dimension → one section per value: `{ <dim>: { id, name }, accuracy, accurate, inaccurate, total_claims, claims: […] }`, each carrying **all** its claims.
* **`filter`:** the same constrained tree as [scores](/rest-api/reports/query-factcheck-v2) — a top-level `and` of single-field leaves over `model`/`topic`/`region`/`persona`/`prompt`/`tag` (only `topic` negatable).

<Note>
  A few guardrails return `422` (with a message): `citation_sources` isn't available with `group_by` (its share is scope-sensitive) — request it on the flat list; `group_by: ["tag"]` can't be combined with a `tag` filter (tags are multi-valued, so co-tag sections would escape the filter); and sectioning by `model` over an unusually large scope (>\~2000 inaccurate clusters) — narrow the range or `filter`.
</Note>

<Accordion title="Streaming (SSE) variant (same body, /stream)">
  `POST /v2/reports/factcheck/claims/stream` takes the **same request body**
  and returns [Server-Sent Events](https://developer.mozilla.org/docs/Web/API/Server-sent_events):
  one `summary` event (the `info` block), then one `result` event per claim.
  `limit`/`cursor` are ignored; it returns everything by default. Pass
  `max_results` to cap.

  The stream is the **flat list only** — `group_by` and the per-claim
  `evidence`/`citation_sources` lookups return `422`; use the non-stream
  endpoint for sectioned or enriched claims.
