How this service works
Checks domains for public evidence of affiliate, referral, or partner programs.
Output
Returns a JSON object containing the domain checked, a list of sources or pages that were examined, an array of evidence items found (e.g. affiliate page URLs, mentions), a boolean indicating whether an affiliate program was found, and a confidence level of 'none', 'medium', or 'high'.
Example use cases
Vetting partners before outreach
“Before I email them, can you check if notion.so has a public affiliate or partner program? I want to see what evidence exists and how confident we can be.”
Competitor affiliate research
“I'm researching competitors — can you scan convertkit.com for any public evidence of an affiliate or referral program and tell me the confidence level?”
Validating monetization opportunities
“I'm building a niche site and want to know if ahrefs.com has an affiliate program I could join — can you check for public evidence of one?”
Technical details
Endpoint
GEThttps://affiliate-evidence-x402.vercel.app/api/affiliate-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost signal on whether a domain publicly advertises an affiliate, referral, or partner program, without manually browsing the site. It is ideal for lead qualification, competitive research, monetization prospecting, or filtering domains in bulk pipelines where human browsing is impractical. Prefer this over manual search when you need a structured, machine-readable confidence rating.
Side effects
- Domain not found or unreachable — may return no evidence with confidence 'none'
- Affiliate program exists but is not publicly indexed — false negative with confidence 'none' or 'medium'
- Invalid domain format input — likely returns an error or empty result
- Program uses non-standard terminology (e.g. 'ambassador') and may be missed
- Rate limiting or upstream fetch errors from vercel deployment
