Calling RPC tx/hash=value with curl only works if you remove the quotes around the hash value and include the 0x prefix. Making this work with an RPC client using JSON-RPC (say in Python) seems to be nearly impossible. Quoting the hex string and including an 0x prefix returns a 400 bad request error. Any other permutation of the hash value doesn't seem to work either. The errors are a bit misleading.
