## About

## What it does
Domain Authority Metrics lets you look up authority-style metrics for a domain name. Send a `domain` string and get back whether a match was found, the original `query`, and a `result` object when the domain exists in the source data.

The returned result includes the entity type and entity name, the canonical `domain`, the `source_graph` it came from, and several scoring fields: `pr_pos`, `pr_val`, `pr_score_10`, `pr_score_10_bucket`, `harmonic_val`, and `authority_weight`. If the lookup does not find a match, `found` is `false` and `result` is `null`.

Use Domain Authority Metrics when you need a quick signal for SEO analysis, competitive research, or domain ranking workflows. For example, you can enrich a list of domains before prioritising outreach, building backlink reports, or comparing site authority across a market segment.

The response is simple to consume in downstream automation: check `found`, read the returned `query`, and use the metric fields in your scoring or reporting logic.
