# Posts

> Evaluate an X URL — runs gatekeeper + writer in 0G Compute TEE.

## POST /posts/evaluate

Pulls an X post via RapidAPI's `twitter241`, scores it with the gatekeeper model, and (if eligible) runs the writer to draft a market proposal. Seals the judge prompt to 0G Storage and persists the proposal in SQLite, keyed by the resulting merkle root.

Body:

```json theme={null}
{ "url": "https://x.com/Cointelegraph/status/2049122930903089617" }
```

Response (eligible):

```json theme={null}

  "postMetadata": { /* … same shape as Market.postMetadata … */ }
}
```

Response (rejected): `{ "eligible": false, "score": {...}, "reason": "..." }`.

The frontend takes the `judgeStorageRoot` and feeds it into `MarketFactory.createMarket(...)` so the on-chain market and the API's cached proposal stay linked.
