Consuming Inventory
Once the transaction is processed, you can fetch inventory for a given account_id – your system's unique identifier for the Account object.
/v1/inventory
Requests to /v1/inventory return both the summary and lots for a given asset. Immediately following the above purchase, the account has a single lot in inventory with a cost of $20,005 (the purchase price plus fee):
curl --request GET \
--url 'https://api.multi1.enterprise.taxbit.com/v1/inventory?account_id={{account_id}}&asset_code=BTC' \
--header 'authorization: Bearer {{token}}'
HTTP/1.1 200 OK

/v1/inventory/summaries
Requests to /inventory/summaries return summary-level detail for each asset held in inventory. Let’s extend the above example to buy another bitcoin (for $40,000) and a single Ethereum token for $2,000.
First, let’s add another transaction to acquire the Bitcoin by calling /transactions/external-id
curl --request POST \
--url https://api.multi1.enterprise.taxbit.com/v1/transactions/external-id \
--header 'authorization: Bearer {{token}}' \
--header 'content-type: application/json' \
--data '{
"account_id": "{{account-id}}",
"id": "2",
"datetime": "2024-01-02T12:13:14.123Z",
"type": "trade",
"fees": [
{
"asset_amount": {
"amount": "5.00",
"asset": {
"code": "USD",
"type": "fiat"
}
},
"rates": [
{
"amount": "1.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"received": [
{
"asset_amount": {
"amount": "1.00",
"asset": {
"code": "BTC",
"type": "crypto"
}
},
"rates": [
{
"amount": "40000.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"sent": [
{
"asset_amount": {
"amount": "40000.00",
"asset": {
"code": "USD",
"type": "fiat"
}
},
"rates": [
{
"amount": "1.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"version": "2.0"
}'
Now make a second request to /transactions/external-id to acquire ETH:
curl --request POST \
--url https://api.multi1.enterprise.taxbit.com/v1/transactions/external-id \
--header 'authorization: Bearer {{token}}' \
--header 'content-type: application/json' \
--header 'user-agent: vscode-restclient' \
--data '{
"account_id": "{{acount-id}}",
"id": "3",
"datetime": "2024-01-03T12:13:14.123Z",
"type": "trade",
"fees": [
{
"asset_amount": {
"amount": "5.00",
"asset": {
"code": "USD",
"type": "fiat"
}
},
"rates": [
{
"amount": "1.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"received": [
{
"asset_amount": {
"amount": "1.00",
"asset": {
"code": "ETH",
"type": "crypto"
}
},
"rates": [
{
"amount": "2000.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"sent": [
{
"asset_amount": {
"amount": "2000.00",
"asset": {
"code": "USD",
"type": "fiat"
}
},
"rates": [
{
"amount": "1.00",
"asset": {
"code": "USD",
"type": "fiat"
}
}
]
}
],
"version": "2.0"
}
'
Now a request to /inventory/summaries will return a summarized view of all the assets for the given account (both BTC and ETH)
curl --request GET \
--url 'https://api.multi1.enterprise.taxbit.com/v1/inventory/summaries?account_id={{account-id}}' \
--header 'authorization: Bearer {{token}}'
HTTP/1.1 200 OK
Content-Type: application/json
{
"data": [
{
"asset": {

"name": "Bitcoin",
"code": "BTC",
"type": "Crypto"
},
"fiat_asset": {
"uuid": "df939ab7-b7ed-4216-be63-ca1d2a130396",
"name": "United States Dollar",
"code": "USD",
"type": "Fiat"
},
"summary": {
"total_quantity": "2",
"total_cost": "60010",
"average_unit_cost": "30005",
"total_quantity_with_cost_basis": "2"
}
},
{
"asset": {
"uuid": "b7a005b5-f4d5-44ea-ae80-d4f9e8313558",
"name": "Ethereum",
"code": "ETH",
"type": "Crypto"
},
"fiat_asset": {
"uuid": "df939ab7-b7ed-4216-be63-ca1d2a130396",

"total_cost": "2005",
"average_unit_cost": "2005",
"total_quantity_with_cost_basis": "1"
}
}
]
}
And call /inventory/ to see the bitcoin-specific inventory with two lots:
curl --request GET \
--url 'https://api.multi1.enterprise.taxbit.com/v1/inventory?account_id={{account_id}}&asset_code=BTC' \
--header 'authorization: Bearer {{token}}'
HTTP/1.1 200 OK

"type": "Crypto"
},
"fiat_asset": {
"uuid": "df939ab7-b7ed-4216-be63-ca1d2a130396",
"name": "United States Dollar",
"code": "USD",
"type": "Fiat"
},
"summary": {
"total_quantity": "2",
"total_cost": "60010",
"average_unit_cost": "30005",
"total_quantity_with_cost_basis": "2"
},
"lots": [
{
"id": "bb694f5c-d2ef-5ff9-82cc-a73ace56db0c",
"acquisition_datetime": "2024-01-02T12:13:14.123Z",
"term": "short-term",
"quantity": "1",
"fiat_asset_code": "USD",
"cost": "40005",
"unit_cost": "40005"
},
{

"fiat_asset_code": "USD",

"unit_cost": "20005"
}
]
}
}
Each previous transaction acquired a crypto asset in the context of a fiat price captured in the transaction’s rates keys, which serves as a cost basis for the lot. Sometimes lots are acquired without an available cost basis. For example, the following POST requests will create a deposit transaction for 10 Solana tokens:
curl --request POST \
--url https://api.multi1.enterprise.taxbit.com/v1/transactions/external-id \
--header 'authorization: Bearer {{token}}' \
--header 'content-type: application/json' \
--data '{
"account_id": "{{account-id}}",
"id": "42",
"datetime": "2023-01-01T00:00:00.000Z",
"type": "deposit",
"version": "1.0",
"received": [
{
"asset_amount": {
"amount": "10",
"asset": {
"code": "SOL",
"type": "crypto"
}
}
}
]
}'
Querying SOL via /v1/inventory returns a lot without a unit_cost, with the entire quantity included in the summary.total_quantity_missing_cost_basis field:
curl --request GET \
--url 'https://api.multi1.enterprise.taxbit.com/v1/inventory?account_id={{account-id}}&asset_code=SOL' \
--header 'authorization: Bearer {{token}}'
HTTP/1.1 200 OK
