> Whether revenue has been observed on a domain and through which recorded service, as a fact your brief can cite.

**Who asks:** Data team adding citable facts to research briefs

## Example

**Question:** For plausible.io: is it in Megido, has payment been observed and through which service? Answer as JSON and give me a line for the brief.

**Megido calls:**

- `lookup_domain`: 1 found

**Answer:**

```json
{"domain": "plausible.io", "in_corpus": true, "payment_observed": true, "payment_service": "paddle.com", "other_domains": []}
```

For the brief: «Revenue has been observed on plausible.io: its visitors were observed paying for its products; the recorded payment service is Paddle (Megido).»

Real data from the corpus, as of June 2026.

## How your agent answers

1. `lookup_domain` found the domain and returned its recorded payment service and other domains.

## Where it stops

The payment service is one recorded value, not every way a site takes payment. A miss means the domain is not in Megido, not that nobody pays there.

## Ask your agent

```text
For [domain]: is it in Megido, has payment been observed and through which service? Answer as JSON and give me a line for the brief.
