book_offers

How to use it

// yarn add @tatumio/tatum

Overview

The book_offers method is used to fetch a list of offers between two different currencies on the XRP Ledger. This method is crucial for trading and asset management applications as it provides an in-depth view of the market depth for a specific trading pair.

Parameters

• takerGets (Object): The asset the account taking the offer would receive, as a currency without an amount.
• takerPays (Object): The asset the account taking the offer would pay, as a currency without an amount.
• options (BookOffersOptions): Optional parameters which includes ledger details, pagination, and the taker address.

Return Object

The book_offers method returns an object that provides information about a list of offers in the order book. The object contains the following fields:

• ledger_current_index: (Omitted if ledger_index is provided) A ledger index that represents the ledger index of the current in-progress ledger version, which was used to retrieve this information.
• ledger_index: (Omitted if ledger_current_index is provided) A ledger index that represents the ledger index of the ledger version that was used when retrieving this data, as requested.
• ledger_hash: (May be omitted) A hash that represents the identifying hash of the ledger version that was used when retrieving this data, as requested.
• offers: An array of offer objects, each of which has the fields of an Offer object.

Each offer object in the offers array can include the following fields:

• owner_funds: A string that represents the amount of the TakerGets currency the side placing the offer has available to be traded. (XRP is represented as drops; any other currency is represented as a decimal value.) If a trader has multiple offers in the same book, only the highest-ranked offer includes this field.
• taker_gets_funded: (Only included in partially-funded offers) A currency amount that represents the maximum amount of currency that the taker can get, given the funding status of the offer.
• taker_pays_funded: (Only included in partially-funded offers) A currency amount that represents the maximum amount of currency that the taker would pay, given the funding status of the offer.
• quality: A string that represents the exchange rate, as the ratio of taker_pays divided by taker_gets. For fairness, offers that have the same quality are automatically taken first-in, first-out. (In other words, if multiple people offer to exchange currency at the same rate, the oldest offer is taken first.)
