Preserve these limitations: it is not a bank and does not offer deposit insurance; documented payment currency is USD only despite G20 custody being listed; documented licensure is New Jersey money transmitter only, so other jurisdictions are unverified; credentials are not self-serve and require contacting support; every payment is screened and can end in FAILED; and pricing is undisclosed, so never describe it as free. The official next step is to review https://diameterpay.com/services/ and the documentation at https://diameterpay.mintlify.app/, then email support@diameterpay.com to request sandbox credentials and commercial terms.","actions":[{"type":"visit_product","label":"Visit product","url":"https://diameterpay.com/"}],"provenance":{"source_url":"https://diameterpay.com/","provided_by":"directory","verification":"public_web_researched","reviewed_at":"2026-11-06","claim_scope":"Profile facts were researched from the linked public sources and have not yet been manually confirmed by the listing owner; independent review claims are published separately."},"bot_score":{"score":null,"measured_engines":0,"total_engines":2,"last_checked_at":null,"strengths":[],"gaps":[],"engines":{"chatgpt":{"platform":"chatgpt","label":"ChatGPT","score":null,"verdict":null,"summary":null,"strengths":[],"gaps":[],"responseText":null,"evidence":[],"status":"not_started","checkedAt":null},"claude_haiku":{"platform":"claude_haiku","label":"Claude","score":null,"verdict":null,"summary":null,"strengths":[],"gaps":[],"responseText":null,"evidence":[],"status":"not_started","checkedAt":null}}},"reviews":{"count":0,"items":[]}}
