# Compound claims

Ask Webcite to check the factual parts of a claim separately.

Documentation index: https://webcite.co/llms.txt
Canonical page: https://webcite.co/api-docs/decomposition
API origin: https://api.webcite.co
Authentication: x-api-key header. Keep keys on your server.

## Enable decomposition

Set `decompose_claim: true` on either `POST /api/v1/verify` or `POST /api/v1/verify/stream`. The default is false.

```json
{"claim":"The Eiffel Tower is in Paris and is 330 meters tall","decompose_claim":true}
```

## Keep each result with its claim

Read each `claim_groups` entry independently. One supported clause does not make every clause supported. Keep source IDs and correction proof quotes within their group. Streaming can emit `decomposition`, `sub-claim-start`, and `sub-claim-result` events before the final result.
