Dear Allen Team,
I have been using the allen api ([https://api.brain-map.org/api/v2](https://api.brain-map.org/api/v2)) and `human_microarray_expression` service as described here [Human Brain Atlas: API](https://community.brain-map.org/t/human-brain-atlas-api/2876). However, for about a month now, my queries to the `human_microarray_expression` service returns an error such as (using the example in the post) `Error in query: service::human_microarray_expression[probes$eq1023146,1023147][donors$eq15496][structures$eq9148], Informatics service request failed.`.
I cannot find any information on the status of the service and all the related links are broken. Is this service deprecated? If so, could you please point me towards an alternative if there is any?
Happy holidays!

Hi @AhmetN: you can access **all** of the human microarray data from the Allen Human Brain Atlas on the download page, here: [Microarray Data Download :: Allen Brain Atlas: Human Brain](https://human.brain-map.org/static/download). I don’t know exactly what the API gives you but I suspect it is a subset of the data in these files. We’ll look into the API issue, but given the holidays it may not be for a couple of weeks. Happy holidays!

Thank you very much for the quick reply, @jeremyinseattle!
Understandable for sure. Looking forward to your feedback about the state of the API 🙂

@AhmetN Thank you for your patience and a good start to 2025 to you.
We identified and resolved the underlying issue. All the queries should work as expected again.
Please let us know if you run into any further issues.

Hi @SvenOtto and @jeremyinseattle , it seems the issue is back as reported intially. Would you mind taking a look at it?

Confirming this is happening again as of June 30, 2026. Same error on a fresh query:
`service::human_microarray_expression[probes$eq1020500][structures$eq4254]`
Returns:
`"Error in query: ... Informatics service request failed."`
Tested with single probe, single structure, and with no structure filter at all — all fail the same way. Using the bulk download page as a workaround for the time being but thought I’d mention this…
