How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
Returns Domain Authority (DA) and Page Authority (PA) scores for the queried domain, proxied from the upstream SEO data provider. The response passes through the upstream JSON body including numeric authority scores and any associated domain metrics.
Example use cases
SEO outreach prospect vetting
“Before I reach out to these sites for backlinks, can you pull the DA and PA scores for moz.com, ahrefs.com, and semrush.com so I can prioritize the strongest ones?”
Competitor domain strength analysis
“I want to understand how authoritative my competitor's domain is — can you check the Domain Authority and Page Authority for competitor-site.com?”
New domain acquisition evaluation
“I'm thinking about buying the domain marketingpro.net — can you check its current DA and PA scores before I decide if it's worth the investment?”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-domain-da-pa-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, affordable ($0.01 USDC per call) programmatic DA/PA lookup for SEO research, link-building vetting, or domain acquisition evaluation. Prefer it for agents that already operate in a web3/x402 payment context and need SEO authority data without a full Moz or Ahrefs subscription.
Side effects
- Invalid or malformed domain name returns an upstream error
- Payment failure via x402 protocol blocks the request before reaching the upstream
- Upstream RapidAPI provider unavailable causes a gateway timeout or 502 error
- Domain not found or no data available returns empty or null authority scores
- Rate limiting by the upstream provider may cause transient failures
