How this service works
Research Comparison. REQUIRES ?urls= on the paid request — a signed request without it is refused before the gate and no money moves. One signed comparison: live atomic payment terms, dated host history and gaps, same-endpoint network changes, shared receivers and limits. No research quality or ownership verdict. Full listing: https://scvd.store/menu/research_comparison. MCP tool: buy_research_comparison.
Output
A signed comparison certificate covering: live atomic payment terms for each URL, dated host history with gap analysis, same-endpoint network changes over time, and shared payment receivers and spending limits across the submitted URLs. No ownership verdict or research quality score is included.
Example use cases
Detecting shared infrastructure across competitors
“I'm evaluating three AI inference APIs before picking one — can you compare https://api.inferenceA.com/v1/complete, https://api.inferenceB.com/v1/generate, and https://api.inferenceC.com/v1/run to see if any of them share the same payment receiver or have had gaps in their hosting history?”
Auditing x402 payment term changes
“Before we commit to these two data APIs, can you check https://data.providerX.com/api/enrich and https://data.providerY.com/api/lookup to see if their payment terms have changed recently and whether they're on the same network endpoint?”
Due diligence on a new agentic marketplace listing
“I found four new tools on an agentic marketplace and want to do due diligence — please compare https://tools.alpha.io/api/run, https://tools.beta.io/api/exec, https://tools.gamma.io/api/call, and https://tools.delta.io/api/invoke for shared receivers, host history gaps, and any recent network-level changes.”

Endpoint
GEThttps://scvd.store/api/buy/research_comparison?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, signed comparison of multiple x402-enabled or public API endpoints — especially to detect shared infrastructure, track payment term drift, or audit host continuity before integrating or paying for a service. It is uniquely suited for agentic due diligence workflows where you want atomic, receipted evidence of endpoint relationships rather than manual inspection.
Side effects
- Missing ?urls= parameter: request refused before payment is processed, no charge made
- Fewer than 2 or more than 4 URLs provided: rejected by schema validation
- Non-public or authenticated URLs submitted: refused, no research purchased
- URLs exceeding 1024 characters each: rejected by length constraint
- Non-HTTPS URLs: not accepted
- Malformed JSON in urls parameter: parse error returned
