Despite I use English in my work, I'm not a native English speaker. And I found myself writing the following sentence:
I thought it would might use an API.
After reading the phrase one more time, it sounded odd. The use of these two modal verbs combined seems wrong (or weird, at least). If that's the case, why is it wrong?

It is wrong. Modal verbs, like can, might, would etc. are "defective", they have no participle (canning, mighting) and no infinitive ("to can", "to might")
A modal verb "would" is followed by the bare infinitive for example "be":
But might has no infinitive, so "it would might use..." is incorrect. You can search for "double modal" for further details on this.
You can use other ways of indicating the "might" modality. In this case the adverbs "possibly" or "perhaps" has a similar meaning.
or just using "might" on its own is correct, with the same meaning as "would possibly"
