Create a Direct Inscription Order

Ordinalsbot supports simplified inscriptions that avoid the need to do additional commit transaction, thus reducing the cost of inscription.

Use this endpoint to create a direct inscription order that will be processed once the deposit address is funded.

• There's currently a limit of 10000 files per order.

• If you choose to send file contents as base64 or text encoded dataURL instead of url, there's a limit of 50MB per API call.

• Currently only internally hosted URLs are supported so if you're dynamically generating files, send them as dataURL which will automatically be uploaded to OrdinalsBot buckets.

• The /inscribe endpoint has a rate limit of maximum of 2 requests every 10 seconds.

• There is a slight delay between the time the order is created and the charge address appears. You will need to poll the order after it is created to see the charge address. See /order

• The deposit address for parent inscriptions will appear on the depositAddress field for each parent object, after which the order enters into a waiting-parent state. Make sure to send parents first, before paying the charge

• When paying for an order with multiple parent inscriptions make sure to craft a transaction such that you send the parents first, to the depositAddress of the parent array and send the charge payment last. You can do this all in a single transaction.

Example of parent/child order with a delegate

Inscription properties:

• one delegate inscription of 0426b1e763be8f7b6cff7bc05640534f506d174dc6f14b57ce146bc37a553b06i0

• three parents

• chosen prefix "00"

Result: https://ordinals.com/inscription/00ee0087bb02437ed3eab12089442f24fd367fe827989372871e196e6bcec218i0

When depositAddress becomes available on each parent object and address under the charge object you can exectute sending of the parents and paying the charge in a single transaction. The only requirement is that you send the parents before you send the charge. Here is an example of a funding transaction to an order of this type: https://mempool.space/tx/165987ba58ddfea7d8b4d0adfbc89b271bd01b7bcd911e2eb2ed5e431e3ad4a2

• the three parents are sent first

• the charge payment is sent last
