How this service works
Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).
Output
Returns a JSON object with ok (boolean), tool name, status string, and a summary of the typosquatting analysis — including detection of lookalike or misspelled domain variants that could represent phishing or brand abuse threats. Failed analyses return HTTP 503 and are not billed.
Example use cases
Monitor competitor domains for phishing threats
“I'm worried that bad actors might be creating lookalike domains to impersonate our competitor TechVendor Inc. Can you scan for typosquatting variants of 'techvendor.com' and tell me if there are any suspicious lookalike domains out there that could be used for phishing?”
Protect client brand from domain abuse
“We manage marketing for several financial services clients. Can you check if 'firstnationalbank.com' has any typosquatting variants or misspelled domain lookalikes that could be used to trick their customers into phishing sites?”
Investigate suspicious domains in threat intel
“During our security investigation, we found someone registering domains that look suspiciously similar to 'applesecurity.io'. Can you analyze this domain and detect any typosquatting or brand impersonation attempts that might be part of a broader attack campaign?”
