How this service works
Compará pasarelas de pago en Argentina: fees, liquidación e integraciones. Directorio independiente ecommerce-first.
Output
Returns a JSON quote ticket with: the USDC output amount (usdc_out, rounded to 6 decimals), the fixed stub rate (1400 ARS/USDC), the input ARS amount, the timestamp of the quote (quoted_at), a settle:false flag confirming this is quote-only and not an on-chain settlement, directional metadata (ars_to_usdc), and disclaimer notes in Spanish.
Example use cases
Pre-trade USDC amount check
“Before I finalize anything, can you get me a LupaPago quote for how much USDC I'd receive if I converted 250,000 Argentine Pesos? Just the estimate, no actual transfer.”
ARS savings to stablecoin valuation
“I have 500,000 ARS in savings and want to know what that's worth in USDC right now according to LupaPago's FX ticket — give me the quote.”
Cross-border payment budgeting
“We're planning to send a payment that requires USDC but we're starting with Argentine Pesos — can you pull a LupaPago ARS to USDC quote for 1,000,000 ARS so I can see how much USDC that covers?”
Technical details
Endpoint
GEThttps://lupapago.com/api/fx/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick ARS-to-USDC conversion estimate using LupaPago's fx-quote-v1 ruleset, especially within Argentine payment workflows or before initiating a full x402 USDC settlement. Prefer this over live-market FX endpoints when a stub/reference rate is acceptable for budgeting or UI display. Do not use when you require actual on-chain settlement or a live interbank rate.
Side effects
- Invalid or missing amount_ars (non-integer or centavo values rejected — whole ARS only)
- Negative or zero ARS amount
- Payment not provided or incorrect (endpoint costs $0.02 USDC via x402)
- Rate is a fixed stub (1400 ARS/USDC) and does not reflect live market — stale rate risk
- No settlement occurs — callers expecting on-chain execution will be disappointed
