2026

v2.5.0 LATEST

Latest published release, recommended unless you need an older version.

  • Added: Payment Safety Checker: before you send money, get an instant breakdown of whether the payment method is reversible, what consumer protections apply, and safer alternatives. Powered by POST /v1/payment-safety.
  • Added: Contract Clause Translator: paste any terms, offer email, or agreement and get plain-language explanations with exact sentence citations and severity ratings. Powered by POST /v1/contract-clauses.
  • Added: Offer Monitor: set a URL once and get a record of every change so you have evidence if terms shift after you've paid. Free: 1 monitor, Starter: 10, Pro: 50. Powered by POST /v1/monitors and related routes.
  • Fixed: Webhook delivery tests no longer time out. The async contract was racing against an 11-second internal retry delay; tests now attach .catch() without await.
  • Improved: Homepage Verify Suite section: all four tools now show Live badges with direct links.
  • Improved: Copy pass across all public pages: replaced em-dashes with natural punctuation and removed stiff phrasing throughout.
  • Improved: Terms of Service and Privacy Policy rewritten with plain language, governing law (California), GDPR and CCPA rights, no-AI-training clause, and explicit data retention timelines.

v2.3.0

  • Added: Sprime Verify: submit any URL to get a real-time trust assessment with WHOIS, TLS, DNS, and content signals bundled into a structured Proof Pack report.
  • Added: GET /v1/verify?url= endpoint works without an API key for one-off checks; authenticated requests get plan-level cache TTL, Firestore logging, and quota tracking.
  • Added: Verify hero on the homepage: paste a URL, get an instant inline preview, then open the full report at /verify.html.
  • Added: URL handoff via ?url= query param: the homepage prefills and auto-triggers the verify input on the report page.
  • Added: Signed-out users see a save-CTA strip after a successful verify check, prompting account creation to unlock report saving and watchdog alerts.
  • Improved: Design refresh across all pages: aurora ambient glow, scroll-reveal animations, button shimmer, and gradient accent bars on featured pricing cards.
  • Fixed: Copy pass across all public pages: removed em-dashes, humanized stiff phrasing throughout.
