POST price estimates

Get Inscription Price (in satoshis)

POST https://api.ordinalsbot.com/price

This endpoint will calculate all fees related to the operation and return the total as well as the breakdown.

Price breakdown

Here is a code example with the exact calculation used in pricing

const discounts = []; // array of discounts applied to the order

// set at 10% at the moment but can be changed
const chainFeeRate = 0.1;

// the parameters that are discountable
// those are the values AFTER the discount
const {
  baseFee, // base fee charged by us, per item
  rareSatsFee, // fee for rare sats, per item
  collectionServiceFee, // optional fee for collections, per item
} = dicountParamters;

// the other components of the pricing, which are not discountable
const {
  chainFee, // chain fee in sats for the whole order
  count, // items count
  postage, // the postage per item
  price, // the price per item for a collection or launchpad
  additionalFee = 0, // zero by default unless specified, applies PER item,
  sizeFee, // normally 10% of chain fee but does not apply for direct orders
} = basePricing;

// the total additional fee that we will charge
const additionalFeeCharged = additionalFee * count;
// service fee component calculation
const serviceFee = (baseFee + rareSatsFee + collectionServiceFee + postage + price) * count + additionalFeeCharged + sizeFee;
// final amount, this is what the user has to pay!
const amount = serviceFee + chainFee;

// this is returned by the endpoint
const finalPricing = {
  ...basePricing,
  ...discountParameters,
  additionalFeeCharged,
  discounts,
  amount,
  serviceFee,
};

Discount object

If discounts are applied there will be an array of discount object in the discounts field

{
  discount: number, // the value of the discount, either as sats or as a percent
  parameter: 'baseFee' | 'rareSatsFee' | 'collectionServiceFee', // which parameter is getting the discount
  type: 'fixed' | 'percentage', // if fixed, we directly deduct dicount from parameter, otherwise we deduct as a % from the parameter
  reason: string, // the reason for discount
}

Non Standard Transaction Fees

We use https://slipstream.mara.com/ to submit any non-standard transactions (larger than 400kb mempool policy limit) to be included in the bitcoin blockchain.

This means you need to check for their minimum fees before submitting a managed order request that will require a non-standard transaction.

You are also bound by ToS of slipstream if you create a managed inscription order with any file larger than 400kb or batch inscription request that would lead to a transaction that is over the default bitcoin mempool policy limit.
