Verigrace builds credible public front doors and delivers evidence-backed technical reviews. Every deliverable is written by a pipeline, verified by hand, and shipped on a fixed schedule — no estimated metrics, no fabricated history.
以实时事实校准判断：交付物先跑通、再核验、后交付；不编数字，不承诺做不到的事。
Claims are checked against live data before they reach a deliverable. If a check cannot run, the report says so instead of guessing.
Read-only observations, time-bounded work, and deterministic checks. You get the artifact, the method, and the limits in one package.
When a source is unreachable, the deliverable records that fact rather than filling the gap. A missing answer is stated as a missing answer.
Four service lines, all delivered as documents or deployed pages. Every line starts with an email brief and ends with an artifact you can inspect. Fixed prices, fixed timelines, no subscription.
A credible public front door: responsive one-page site with copy, SEO keywords, and a working contact form. Chinese or English. Delivered as static files you host anywhere, or deployed for you.
Deterministic review of a live URL: DNS records across independent resolvers, HTTP health and redirect chain, SSL expiry and chain validity, security headers scoring, email authentication (SPF/DKIM/DMARC), and lookalike-domain exposure. Findings ranked, each with a reproduction command.
A question answered against primary sources, not search summaries. Regulatory text quoted with article numbers and retrieval dates; protocol claims checked against the specification repository; every assertion carries a source URL and a confidence level. Unverified items are labelled unverified.
Original step-by-step math, physics, and chemistry solution animations for middle-school exam preparation — lecture notes, an HTML player, and matching figures. Produced by an automated content pipeline, reviewed for correctness before release.
The same path for every service line. Nothing starts before step 2, and nothing is charged before step 4.
One email with the target — a URL, a business name, or a question. No account, no form, no signup.
A written reply stating what will be delivered, the price, and the delivery date. If the request is outside what we can verify, we say so instead of taking the job.
The deliverable is built, then each claim is re-run against its source. Checks that fail are reported as failures.
Files, a deployed page, or a report with reproduction commands. Payment is arranged after delivery is accepted.
We do not sell estimated metrics presented as measurements, fabricated history, or reports claiming checks that were never run. If a data source is unreachable from our network, the report records the gap instead of filling it. If we cannot verify a claim, it is labelled unverified.
