We wish to deliver against the Prices API RFP - we already operate a pricing API that has served hundreds of millions of free queries with 99.99% uptime. It powers multiple wallets and our own payments system. That said, it reflects the era it was originally built in around 2020. While we’ve modernized parts of it, it would need a substantial upgrade to meet enterprise grade expectations today.
The current system aggregates data from 16 sources, removes outliers, supports source weighting, and can generate composite rates. For example, to calculate XLM:BRL it may derive a route via XLM:BTC and BTC:BRL, including multi step paths where necessary. We also support a nested query mode that exposes underlying source data so downstream developers can apply their own logic, alongside a more opinionated single rate endpoint.
You can see an example query here: https://rates.ctx.com/rates?symbol=xlmeur&nested=1
