https://api.1151.to. The platform maintains addresses, signatures, and broadcasts so your teams only have to orchestrate when wallets are created, queried, or spend funds.
Supported networks and assets
| Network | Capabilities |
|---|---|
Bitcoin (btc) | A single receiving address per wallet, automatic UTXO management, and BTC spends. |
Ethereum (eth) | EOAs that can transfer native ETH or ERC-20 USDC/USDT. |
Tron (tron) | Mainnet or Nile testnet wallets that support native TRX and TRC-20 USDT. |
testnet: true during creation. Ethereum wallets use Sepolia, Tron wallets use Nile, and Bitcoin wallets target testnet3 (with testnet4 support coming soon).
Lifecycle at a glance
- Create a wallet with
/wallet/createand receive its ID (w_<uuid>) plus the on-chain address. - Retrieve metadata through
/wallet/getusing the ID, address, or wallet name. - Transact via
/wallet/sendto broadcast native or token transfers. - Inspect Bitcoin spendable outputs with
/wallet/utxos. - Delete a wallet through
/wallet/deletewhen it is no longer needed.
Plan limits
| Plan | Included wallets | Notes |
|---|---|---|
standard | 5 | Hard cap. Creating a fourth wallet returns HTTP 403. |
scale | 100 | Additional wallets stay active and are billed as add-ons. |
large | 1000 | Same behavior as scale with a larger included quota. |
Wallet data model
| Field | Description |

Next steps
- Review endpoint contracts in the Wallet API reference.
- Use the JavaScript SDK guide or Python SDK guide for faster integration.
- Add defensive error handling: non-2xx responses include an
errorfield, while/wallet/sendcan returnresult: "fail"with provider feedback.
