Worth it if you're building a fintech in Latin America and need a fiat↔stablecoin on/off-ramp with local rails and documented GraphQL/REST APIs.
Avoid it if you're an individual or operate outside Latin America: it's B2B infrastructure not accessible to end consumers.
Koywe is a Y Combinator-backed crypto infrastructure company offering compliant on-ramp and off-ramp APIs across Latin America. It provides well-documented APIs (GraphQL and REST) and SDKs with local rails, so developers and fintechs can use stablecoins for services such as remittances, USD wallets and investments. It is active in the main LATAM markets (including Chile, Brazil, Argentina, Mexico).
