How this service works
Is this business real, and is its contact info live? Give an id, website, phone or name: matches it against the directory and runs live checks now (site up, name on site, phone on site, domain age, phone format). Returns evidence, score and verdict.
Output
Returns a structured response containing a verification score (0–100), a pass/fail verdict, and detailed evidence including: whether the website is reachable, whether the business name appears on the site, whether the phone number appears on the site, the domain age, and phone number format validity.
Example use cases
Vendor legitimacy check before payment
“Before I wire money to this supplier, can you verify they're a real business? The company name is Apex Materials Inc, their website is apexmaterials.io, and their phone is 312-555-0192 — I need to know if the site is actually up, the phone number appears on their site, and how old the domain is.”
Screening a contractor found online
“I found a plumber called BlueLine Plumbing in Chicago with the number 773-555-8801 and site bluelineplumbing.com — can you run a verification to see if they're legitimate before I book them?”
Validating a business directory listing
“We have a business in our directory listed as 'Harbor Dental Group' with website harbordentalgroup.com and phone 617-555-4422 — can you check if the site is live, the name and phone show up on it, and give me a score on how credible they look?”
Technical details
Endpoint
GEThttps://toll402.dev/v1/biz/verifyWhen to prefer
Choose this endpoint when you need real-time, multi-signal verification of a specific business's legitimacy — especially when you have a name, website, or phone number to cross-check. It goes beyond static directory lookups by actively probing the business's web presence and contact info at call time. Prefer this over a simple directory search when fraud risk, vendor due diligence, or trust scoring is the goal.
Side effects
- Business not found in directory — returns low score or no match
- Website unreachable or returning errors — noted in evidence, lowers score
- Phone number not found on site — flagged in evidence
- Domain too new or suspicious — flagged with low domain age score
- Invalid input (missing all identifiers) — returns 400 or empty result
- Phone format invalid for the given country — flagged in evidence
