Very well. I have two questions.<p>Why should one use this service, instead of using directly ecb(<a href="https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml" rel="nofollow">https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xm...</a>)?<p>How do you keep this service free since there is a server cost?
If you're interested in offering a paid version of this API with no extra work, let me know. I think it'd be interesting to consider what additional features your users might pay for.<p>I'm the founder of <a href="https://saasify.sh" rel="nofollow">https://saasify.sh</a> btw which auto-generates full SaaS products from this type of core API functionality.
How is it different from frankfurter.app ? (from the original creator of fixer.io)<p>Side note: I always wonder about those stories like uBlock Origin and fixer.io where the original author sold or lost control of the product and then restarted a fork of their own work :) there’s something slightly weird and fun about it somehow
One other API I've found that includes foreign exchange (as well as a bunch of other different asset classes) is <a href="http://iexcloud.io" rel="nofollow">http://iexcloud.io</a> -- they have a free tier that is pretty generous.
We use <a href="https://openexchangerates.org/" rel="nofollow">https://openexchangerates.org/</a> and they also have a free plan. I’d love to know how you compare. They do commodities (silver, gold, etc) and some crypto. What is your USP?
One thing to be careful of when using 3rd party exchange rate services: make sure they are using the right rate source for your needs.<p>For example, if you need the exchange rate on order to convert a quarter's sales from some non-EUR currency to EUR for quarterly VAT MOSS reporting, you are supposed to use the rate reported by the European Central Bank on the last reporting day of the VAT MOSS quarter.<p>The submitted service is using ECB, so should be fine for that specific use case.
Do you monetize the query stream to inform fourex investment decisions? What if they are adversarial to my intent? You profit from asymmetric knowledge.<p>If you detected you could leverage an advantage by lying about the rates, what constraints are there and how do we know?<p>Banks are highly regulated. What's your regulatory oversight.<p>Profitable information is hedged by conditions. Therefore beset by utility limits.
This is a bit unrelated, but how do folks make those nice shiny landing pages like this one, which all seem to have almost the exact same layout and format (e.g. the animation with the little people at the top and the link to learn more, along with the tiles in the middle with different features). I'm interested in launching products like this while doing as little frontend work as humanly possible.
This is a great service and I’d like to thank the developer regardless of whether there are other services out there that provide similar services.<p>Why do I say this? I’ve just spent the last year and a couple of solid corona weeks doing some development on a personal project which requires historical access (-1 day mostly) to high / low / open / close data on all LSE companies.<p>I’ve hunted round for companies that offer this as an api even as a paid service and I’ve found it ridiculously difficult to get data. Most of the product offerings mean I have to login each time, download a file and parse the cvs or pay for access to incrementally tiered historical data.<p>In the end I’ve had to scrape data which costs a lot in processing time.<p>My point is here that this will be useful to someone somewhere. And I’m willing to bet they are also willing to pay for it.
I usually don't care much about such things but how are you financing this project? I did not see any evidence of a paid plan.<p>If I were going to depend on this I'd like some assurance that you'd be able to keep it going. That you've run it for 12+ months (I think) is helpful.

I'm really interested in using this, I just can't seem to easily find the 33 currencies that are supported. Any chance you could clarify which ones?
I host a service too.<p><a href="https://exchange-rate.bai.uno/" rel="nofollow">https://exchange-rate.bai.uno/</a><p>- free<p>- based on Eu Bank, update daily<p>- host on a EC2 instance
offtopic - I wonder if it's possible to make arbitrage only by switching currencies setting aside commissions.
ie - Exchanging USD > EUR > RUB > ILS > HKD > back to USD --> Profit!!!1
