How this service works
Domain Competitors: Find organic competitors for any domain. Priced below typical SEO-data APIs. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/domain_competitors.
Output
A JSON object containing a list of competing domains ranked by their organic search overlap with the queried domain, including relevance signals and competitor metadata up to the requested limit.
Example use cases
SEO competitor audit for a client
“Pull the top 15 organic search competitors for hubspot.com in the US — I'm doing a competitor audit and need to know which domains are fighting for the same search traffic.”
Market research for a new product launch
“Who are the top 10 organic SEO competitors for notion.so in English? I'm researching the market before we launch our new productivity tool.”
Localized competitive analysis for a regional market
“Find the top 25 organic competitors for amazon.de — use German language results and set the location to Germany. I need to understand the competitive search landscape there.”
Technical details
Endpoint
POSThttps://x402.freeq.one/tools/domain_competitors?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call SEO competitor discovery without signing up for expensive SEO platform subscriptions. Ideal for AI agents needing on-demand competitive intelligence for any domain, especially in workflows where you want to pay per lookup in USDC rather than commit to a monthly SaaS plan. Prefer over full-suite SEO APIs when you only need competitor domain lists rather than full keyword or backlink data.
Side effects
- Invalid domain format (no protocol, paths, or subpaths allowed — must be bare domain like example.com)
- limit out of range (must be 1-100)
- Invalid location_code returns no results or error
- Payment failure via x402/USDC results in 402 response blocking the call
- Domain with no indexed competitors returns empty result set
