How this service works
Directorio público de x402, AP2, ACP y MPP. Fuente + fecha. No inventamos precios ni estados.
Output
A JSON object containing the evaluated payment case (e.g. m2m_usdc, fiat_consent, checkout), the applicable rail (e.g. x402), the rail's role (settle, consent, checkout), whether an ARS fiat hop is needed, and a hub URL with further documentation in English and Spanish, all governed by the ar-rail-matrix-v1 ruleset.
Example use cases
Choosing rail for M2M USDC payment
“I'm building an agentic system that makes HTTP 402 USDC payments between machines in Argentina — check the LupaRiel rail matrix for the m2m_usdc case and tell me which rail applies and whether I need an ARS fiat conversion step.”
Validating fiat consent hop requirement
“My agent needs to collect fiat consent from an Argentine user before charging — query the LupaRiel rail matrix for the fiat_consent case and tell me which rail role applies and what hub URL to reference.”
Checkout flow rail classification
“I'm setting up a checkout flow for an Argentine agentic product — run the LupaRiel rail matrix for the checkout case and tell me whether settle or consent applies and if an ARS hop is needed.”
Technical details
Endpoint
GEThttps://lupariel.com/api/rail/matrix?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically determine which Argentine agentic payment rail (settle, consent, or checkout) applies to a specific payment scenario, especially when building x402-based M2M payment flows or needing to decide whether a fiat ARS hop is required. Prefer it over manual documentation lookups or general payment routing logic when operating within the Argentine agentic payments ecosystem.
Side effects
- Invalid 'case' query parameter value returns 400 with error and hint fields
- Missing required input fields returns a validation error
- Network or service unavailability returns a non-200 HTTP error
- Unsupported HTTP method (e.g. POST) returns 405 or similar error
