1. Source priority

Content is sourced in tiers, with higher tiers preferred whenever available:

  • Tier 1 — official pages. Pricing pages, terms of service, and help-center articles published directly by the AI platforms and payment providers themselves, plus subscription-tier details listed on the App Store or Google Play. This is independently verifiable and the primary basis for anything framed as a verification.
  • Tier 2 — card network and payment-processor public documentation. For virtual card articles, we reference publicly available Visa/Mastercard merchant category code (MCC) documentation and 3DS/AVS verification specs. These explain mechanics — why a charge might trigger a decline or risk-control hold — not the real-world performance of any specific card product.
  • Tier 3 — platform self-reported claims. A service's own claims about itself, e.g. "supports N regions" or "X% success rate." These are always labeled as platform self-reports with a caveat to verify against the platform's latest disclosure and your own testing — never presented as established fact.

2. What counts as a verification step

Where an article gives step-by-step verification guidance, the bar for a step to count as actionable is simple: could a reader act on that single line, without reading anything else in the article? "Compare the merchant name on your card statement against the merchant name in the platform's own billing notice" clears that bar — it names a concrete, independently executable action. "Be careful with your funds" doesn't, because it gives no next step at all. We try to hold every checklist item in payment-failure, billing-anomaly, and virtual-card setup content to this standard rather than leaving it at a general warning.

3. Freshness and staleness disclosure

AI subscription pricing, available models, and payment policy change often. When an article cites a specific price or model name — the kind of detail most likely to go stale — we check it against the platform's own official page before publishing, rather than relying on memory or an old screenshot. Articles with a concentration of this kind of detail carry a separate "pricing and model info last verified" date next to the publish date, so you can judge whether it might already be out of date. More commonly, articles avoid citing numbers likely to change quickly in the first place, preferring phrasing like "check the official page for current pricing" — not to be vague, but because writing a fast-moving number into permanent text tends to mislead readers more than it helps them.

4. Sponsored-content disclosure

Some articles mention third-party tools, such as the RDVCC virtual card service, the AllSwap cross-chain swap aggregator, and chdh.me. These links always carry rel="noopener nofollow sponsored". The rules:

  • Any capability claim from a sponsor is labeled as a platform self-report, never verified or endorsed by this site — you should confirm compliance and suitability yourself before using it.
  • A sponsor mention appears as one example within one section of an article, never as the reason the article exists — the verification method and conclusions don't depend on whether a sponsor is mentioned.
  • Sponsor product descriptions are kept in their own paragraph, not blended into the independently written how-to content around them.

5. Corrections

If you spot outdated pricing, a policy description that's changed, or a broken step in an article, please email us — we prioritize anything that could affect fund safety, account security, or compliance judgment. Updates preserve a changed article:modified_time, so the fact that an update happened is itself visible, rather than silently replacing the body text and leaving no trace that anything changed since publication.
