Is it possible to run a pruned node while being able to verify any TXID?

I am building a web app that implements bitcoin payments. My server has limited resources, and I don't want to fill up it's data with the ENTIRE blockchain (takes up too much space).

So I enabled pruning on bitcoind, and ran:

bitcoind -daemon -txindex

I got the error:

Error: Prune mode is incompatible with -txindex.

Is it not possible to verify any TXID I want with a pruned node? Is my only option to depend on a third party if I don't want to store the entire blockchain? Thanks.

You're asking two different things, so it's not clear which answer is correct.

Yes, a pruned full node verifies all transactions. That's why it's still called a full node.

No, pruning is not compatible with txindex.

But, are you sure you need txindex? If you're only receiving payments to yourself you don't need txindex.

D'oh! I'm not sure why I forgot pruned nodes can still verify payments received to it's own wallet. Thanks. – 2523454 – 2018-02-05T22:18:04.660

1Not just to its own wallet, full nodes (including pruned ones) verify all payments, ever. That doesn't mean you can query them. – Pieter Wuille – 2018-02-06T18:16:57.063
