Symbols missing in live API responses

Incident Report for Open Exchange Rates

Monitoring

Dear clients,

A fix was deployed at ~14:50 (UTC), restoring full service to live API endpoints. We are monitoring the results and working to prevent any possible future recurrence.

Note on API Usage: If your account has made additional requests as a result of this incident and risks exceeding its allowance (or already has), please let us know and we'll make sure your access is not affected for the remainder of your service month. There is no need to upgrade your subscription in this case. If you have already upgraded as a result of unexpected overage, please contact us and we will be happy to help.

If you experience any further issues, please contact us at support@openexchangerates.org.

Thank you for your patience whilst we worked to resolve this issue. We will provide a further update once full remediation is in place.

Note: There is no need to upgrade your account in case of increased usage in response to this incident.

Update

Dear clients,

Thank you for your ongoing patience while we have been working to restore API service. This has been complicated by various factors spanning our application, infrastructure, and data contributor connections.

At present there are 137 currency symbols available in our latest endpoint, which are receiving updates as normal.

The following 35 symbols remain unavailable at this time:

AFN, AOA, AWG, AZN, BRL, CLP, CNY, CZK, DKK, GMD, IDR, ILS, JOD, KGS, KMF, MVR, MYR, MZN, NOK, NZD, PHP, RON, SBD, SDG, SEK, SLE, SRD, TMT, TRY, TWD, VES, XAG, XAU, XCD, YER

Unfortunately, our earlier planned fix was not able to be deployed, due to a small but present risk of this causing further issues under certain conditions. We are continuing to work on restoring the missing currencies, however in light of further work and testing required we anticipate this may take up to another 24 hours. We will continue to update this page with new information.

We sincerely apologise for the inconvenience caused by this outage.

Update

We are continuing to work on this issue and are still testing a potential fix, however we found that this presented a risk of further complications arising under certain conditions. We are now reviewing additional safeguards and will provide further updates as soon as they are available. Thank you for your continued patience.

Update

Dear clients,

We have identified that this incident began during a routine database maintenance procedure. This caused a brief unexpected database downtime, which propagated to the cache and resulted in a large number of currencies disappearing from live API responses. Unfortunately, this then led to a failure in our data contributor pipeline, which is where we are currently working to restore full service.

A fix has been identified and is currently being QA tested, before making the changes to production.

We appreciate your patience while we continue to work on resolution.

Update

We are continuing to investigate this incident and working on resolution. This was caused by a failure in our cache and data supply pipeline, however the root cause is not clear at present.

Since our last update, we have restored the majority of currency symbols to the live latest.json/historical endpoints. There are approximately 38 symbols still unavailable.

We have also restored service to our ohlc.json and spot.json endpoints, however there will be gaps in the available data on these endpoints for affected symbols, between approximately 04:30 and 07:15 UTC.

Please stand by for further updates.

Investigating

Dear clients,

We are experiencing a technical issue with our exchange rates API. A number of symbols (~50) are missing from the live rates API responses, latest.json and other live/historical endpoints, since around 04:35 UTC on 17th January 2026.

We are looking into this urgently and will provide further updates as soon as they are available.
