// API

Same routing engine. Same prices.

The Cambio API exposes the same quoting, routing, and execution endpoints the AI composer uses on the website. REST + JSON. Production-ready. 60 requests per minute on the free tier — higher on request.

What you get.

// SAME ENGINE

Same routing engine the AI uses.

The API serves the same /v1/quote endpoint that powers the on-site composer. Same pricing, same competitor scan, same multi-leg routing decisions. No "API tier" with different rates.

// REAL-TIME

Live competitor comparison on every quote.

Each quote response includes the competitor price strip — up to six recognizable instant-swap brands (SimpleSwap and others) that Bestchange lists for the pair, recognizable names first. Rates are Bestchange aggregator snapshots and may differ from a provider's own direct rate.

// FAIR USE

60 req/min by default. Higher on request.

Free tier covers most integrations. Production-grade integrations (DeFi aggregators, multi-chain wallets, custodial frontends) get elevated limits — email support with your expected throughput.

// ENDPOINTS

Six endpoints. Everything you need.
