One REST API for SEO data and domain intelligence
SEO APIs exist everywhere. Domain valuation, sales history, and WHOIS data in a single REST API alongside keyword and backlink data? That is only BISHOPI.
One API key. One integration. Two data universes. Postman collection included.
curl -X GET "https://api.bishopi.io/v1/domain/valuation?domain=cloudstack.io" \ -H "Authorization: Bearer bsh_live_k7x9..." \ -H "Content-Type: application/json"
{ "domain": "cloudstack.io", "estimated_value": 12400, "currency": "USD", "confidence": 0.87, "comparable_sales": 23, "domain_age_years": 8, "monthly_searches": 4200, "tld_trend": "+12%" }
10 endpoints. One API key. Two data universes.
Domain Intelligence
PROPRIETARY/v1/domain/valuationEstimated value, confidence score, comparable sales count
/v1/domain/salesHistorical sales with price, marketplace, and date
/v1/domain/whoisRegistration data, ownership history, expiry dates
/v1/domain/availabilityReal-time registration availability check
/v1/domain/monitorSet and manage domain watch alerts
SEO Data
/v1/seo/keywordsSearch volume, difficulty, CPC, and trends
/v1/serp/analysisTop 100 SERP results with DA and backlinks
/v1/backlinksBacklink profiles with referring domains and anchors
/v1/trafficEstimated organic traffic and top pages
/v1/competitorsCompetitor keyword overlap and gap analysis
One API, two data universes: Domain intelligence endpoints return proprietary data — valuations, sales history, and monitoring you cannot get from any other API provider. SEO endpoints cover keywords, SERPs, backlinks, traffic, and competitor analysis. One key, one integration, one invoice.
Build with BISHOPI if:
Consider alternatives if:
“We evaluated every domain data API on the market. The valuation and sales history endpoints were the differentiator — that data is proprietary to BISHOPI and we could not source it elsewhere.”

From agency dashboards to registrar infrastructure
SEO Agencies & Platforms
Build white-label SEO dashboards with keyword research, backlinks, and competitor analysis. Add domain valuations as a premium feature no competitor can match — because the data is proprietary.
An SEO platform integrates the valuation endpoint into their domain research view. Their users can now see what a domain is worth alongside standard SEO metrics — a feature Ahrefs and SEMrush APIs cannot provide.
Cybersecurity & Threat Intel
Monitor domain registrations for brand impersonation, phishing detection, and trademark infringement. Track WHOIS changes and new registrations to flag threats early.
A security firm monitors 200+ client brands for lookalike domain registrations. The WHOIS and monitoring APIs flag new registrations in real-time, feeding their automated threat pipeline.
Registrars & Domain Platforms
Enrich your domain search with valuations, sales comps, and SEO metrics. Help customers understand what domains are worth before they buy.
A registrar shows estimated market value and comparable sales during checkout. Premium domain upsells increase because buyers see data-backed justification for the price.
“We use the WHOIS and domain monitoring APIs for brand protection across 200+ client domains. Flagging lookalike registrations in real-time was a game-changer for our threat intel pipeline.”

“We integrated the valuation, sales history, and availability APIs into our domain search. Premium domain upsells increased significantly in the first quarter. The integration took two days.”
One API that combines SEO data with proprietary domain intelligence
Most SEO APIs stop at keywords, backlinks, and SERPs. BISHOPI adds a layer of proprietary domain intelligence — valuations built on real comparable sales, 500K+ historical transactions, WHOIS history, and domain monitoring — that is not available from any other API provider.
