How this service works
Agent-facing decision procedure for the Japan DG stablecoin payment rail launched on USDC/Base for x402 agent payments. Inputs: target merchant or payment location, wallet surface (USDC on Base, Cloudflare Wallets, exchange custody), rail preference, jurisdiction of the counterparty. Outputs: acceptance verdict (reachable via JCB/DGFT 1.3M+ locations, Base-only, or unverified), settlement path with expected latency, fee profile, Japan payment-regulation flags, and dispute surface. Thresholds
Output
Returns an acceptance verdict (reachable via JCB/DGFT 1.3M+ locations, Base-only, or unverified), the settlement path with expected latency, a fee profile, Japan payment-regulation flags, and dispute surface information. Also includes a prose decision brief for agents and an ISO-8601 generation timestamp.
Example use cases
Pre-payment merchant reachability check
“Before I send USDC to this Tokyo convenience store on the DG rail, can you confirm they're reachable via the JCB/DGFT network, what the settlement latency looks like, and whether there are any Japan payment-regulation issues I should know about?”
Exchange-custody wallet compatibility check
“I'm using an exchange-custody wallet and want to pay a Osaka merchant via the Japan DG stablecoin rail — can you verify that rail is compatible with my wallet surface and tell me what fees and settlement path to expect?”
Japan regulatory compliance preflight
“My agent is about to make an x402 payment to a Japan-based counterparty on the Base/USDC DG rail — can you run the acceptance check and flag any Japan payment-regulation issues or dispute surface concerns before we proceed?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/japan-dg-rail-acceptance-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to pre-flight a payment to a Japan-based merchant or location via the DG stablecoin rail on USDC/Base, especially when regulatory compliance, wallet surface compatibility, or settlement certainty is required before committing funds. Prefer this over generic payment-route selectors when the Japan DG rail specifically (JCB/DGFT network) is the target and jurisdiction-specific flags matter.
Side effects
- Merchant or payment location not recognized — verdict returned as 'unverified'
- Unsupported wallet surface or rail preference combination — may return partial or null settlement path
- Japan regulatory flags unavailable for certain counterparty jurisdictions
- LLM-generated brief may have lower confidence for edge-case merchant types
- Payment of 0.002 USDC required; unpaid requests return metadata only (meta=1 mode)
- Network or upstream provider failure returning non-200 response
