json rpc – Get all UTXOs from specific wallet via RPC

I agree with @Pol Espinasa’s explanation above, Bitcoin Core cannot return UTXOs for an arbitrary address unless that address belongs to a wallet that Bitcoin Core has loaded.

For addresses that don’t belong to your wallet, you would typically rely on an indexer or a public data provider instead of scanning the chain yourself.

Full disclosure: I work on Tatum’s indexing infrastructure.

We maintain a UTXO index for all Bitcoin addresses, so you can query any address directly without importing it into a wallet or rescanning:

Here’s the sample request :

curl --request GET \
  --url 'https://api.tatum.io/v4/data/utxos?chain=bitcoin&address=YOUR_ADDRESS' \
  --header 'accept: application/json' \
  --header 'x-api-key: YOUR_API_KEY'

And the sample response :

[
  {
    "txHash": "6cd3bcb491b562ac8931e7684f6cb373c6be9ac4cbad084ee7b1e5b51df88037",
    "index": 2,
    "value": 4.15977295,
    "valueAsString": "4.15977295",
    "address": "bc1q7cyrfmck2ffu2ud3rn5l5a8yv6f0chkp0zpemf",
    "chain": "bitcoin-mainnet"
  }
  ...
]
