Introduction

Welcome to the Chisel API! You can use this API to submit individual or bulk inscriptions, and monitor their status.

Inscriptions

Create Inscription

const data = new FormData();
data.append('fee_rate', 80);
data.append('ordinal_receive_address', 'bc1qdr06k926axngldcpz48fe7vg72085muzxcsfzgp3eajnptnjlk5s5yz38y');
data.append('return_address', 'bc1qguzk63exy7h5uygg8m2tcenca094a8t464jfyvrmr0s6wkt74wls3zr5m3');

// add plaintext file
const blob = new Blob(['Hello World'], {type: 'text/plain'});
data.append('inscriptions', blob, `inscription_0.txt`);

// submit inscription
await fetch('https://chisel.xyz/api/inscribe', {
    method: 'POST',
    body: data
});

The above command returns JSON structured like this:

    "destination": "bc1qdr06k926axngldcpz48fe7vg72085muzxcsfzgp3eajnptnjlk5s5yz38y",

ordinal_receive_address	String	Required	Address to send the inscriptions to.
fee_rate	Integer	Required	Fee rate in satoshis per virtual byte.
fee_rate_decimals	Integer	Optional	Number of decimals to interpret the `fee_rate` parameter. For example, if `fee_rate` is `128` and `fee_rate_decimals` is `1`, the fee rate is interpreted as `12.8`, and if `fee_rate_decimals` was `2`, it would be interpreted as `1.28`.
split_revelations	Boolean	Optional	Should each inscription have a separate revelation transaction?
inscribe_provided_own_ordinal	Boolean	Optional	Set to `true` to enable bringing own satoshi.
parent_inscription_ids[]	String[]	Optional	Array of inscription ID strings that the new inscriptions will become children of.
skip_mime_check	Boolean	Optional	Allow any mime type, including those not yet supported by ord.
postage	Integer	Optional	Value of each inscription's revelation output. Default: `10000`.
compress	`brotli` \| `gzip` (String)	Optional	Compress data using either Brotli (`brotli`) or Gzip (`gzip`).
locktime	Integer	Optional	Add a locktime to the revelation transactions. May not be used in conjunction with `grind_ambifix`.
grind_ambifix	String	Optional	Grind a 1-to-4-character-ambifix for the revelation transactions, making them either start or end with the ambifix. Must be hexadecimal. May not be used in conjunction with `locktime`.
return_address	String	Optional	Address whereto refunds would be sent. If used in conjunction with parent inscription IDs, all parent inscriptions will be sent here.
delegates	String[]	Optional	Array of inscription IDs to use as delegates. Cannot be used in conjunction with the `inscriptions` field. When used, no content or (by default) mime type* gets inscribed.
mime_types	String[]	Optional	Array of MIME types to use with delegate inscriptions only. Length must match delegates.
metaprotocols	String[]	Optional	Array of strings to use as the metaprotocol for each file. Length must match inscriptions.
metadata	File[]	Optional	Array of JSON files to mark as metadata corresponding to each inscription. Length must match inscriptions. `null` indicates no metadata for the inscription at the given index.
destination_address_overrides	String[]	Optional	Array of destination address overrides. Length must match inscriptions. Empty string indicates no destination override for the inscription at the given index.
unbounds	Integer[]	Optional	Array of inscription indices that should be marked as unbound.
allow_nonstandard	Boolean	Optional	Allow the revelation transactions to be non-standard, i.e. change their weight limit to 3.9MB. You will not be able to broadcast your non-standard transaction using the standard relay network!
rune[operation]	String	Optional	Either `etch` or `mint`, depending on the intended rune operation.

Rune Parameters

All Rune parameters are sent within a rune field. So name would correspond to rune[name], etc. When doing rune operations, the inscriptions field is no longer required.

Etching

To etch a rune in conjunction with an inscription, simply keep the inscriptions or delegates field from the submission parameters.

Parameter	Type	Necessity	Description
name	String	Required	Ticker symbol of the rune to be etched. Use periods for spacers. Example: `HELLO.WORLD`.
symbol	Character	Optional	Single character point string.
divisibility	Integer	Optional	Number of decimals to format rune tokens with. Cannot exceed 38.
premine	Integer	Optional	Number of atomic rune tokens to premine.
cap	Integer	Optional	Maximum number of rune minting operations. *Must be used with `amount`.
amount	Integer	Optional	Number of rune tokens to issue per each mint operation. *Must be used with `cap`.
height_start	Integer	Optional	Absolute block height at which the rune should first become mintable.
height_end	Integer	Optional	Absolute block height at which the rune should stop being mintable.
offset_start	Integer	Optional	Relative block offset from the rune's etching at which the rune should stop being mintable.
offset_end	Integer	Optional	Relative block offset from the rune's etching at which the rune should stop being mintable.

Minting

When minting runes, no inscriptions may be specified in the submission parameters.

Parameter	Type	Necessity	Description
id	String	Required	ID of the rune to be minted. Must be in the form `<block>:<tx>`.
count	Integer	Required	Numer of rune tokens to mint.

destination	String	Bitcoin address where the inscription(s) and, if applicable, parent(s) will be sent.
fee_rate	Integer	The fee rate the Chisel-generated transactions will have.
