Endpoint
POSThttps://api.m2mcent.com/domain-authority-checker-mcp/api/process?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call domain authority lookup without maintaining a subscription to a full SEO platform. Ideal for agents performing one-off domain vetting, backlink analysis, or competitor research where a single DA score is needed on demand.
Side effects
- Invalid or malformed domain name returns an error or null score
- Unknown or very new domains may return a zero or very low authority score
- Network timeout if the domain lookup takes too long
- Input field 'data' missing or empty causes a validation error
