Faucets

Endpoints to request STX or BTC tokens (not possible on Mainnet)

Add testnet BTC tokens to address

Add 1 BTC token to the specified testnet BTC address.

    The endpoint returns the transaction ID, which you can use to view the transaction in a testnet Bitcoin block
    explorer. The tokens are delivered once the transaction has been included in a block.

    **Note:** This is a testnet only endpoint. This endpoint will not work on the mainnet.
query Parameters
address
string
Example: address=2N4M94S1ZPt8HfxydXzL2P7qyzgVq7MHWts

A valid testnet BTC address

Get STX testnet tokens

Add 500 STX tokens to the specified testnet address. Testnet STX addresses begin with ST. If the stacking parameter is set to true, the faucet will add the required number of tokens for individual stacking to the specified testnet address.

    The endpoint returns the transaction ID, which you can use to view the transaction in the
    [Stacks Explorer](https://explorer.hiro.so/?chain=testnet). The tokens are delivered once the transaction has
    been included in an anchor block.

    A common reason for failed faucet transactions is that the faucet has run out of tokens. If you are experiencing
    failed faucet transactions to a testnet address, you can get help in [Discord](https://stacks.chat).

    **Note:** This is a testnet only endpoint. This endpoint will not work on the mainnet.
query Parameters
address
string
Example: address=ST3M7N9Q9HDRM7RVP1Q26P0EE69358PZZAZD7KMXQ

A valid testnet STX address

stacking
boolean
Default: false

Request the amount of STX tokens needed for individual address stacking
