Budgets

Allocate per-grant spending budgets, debit usage, check balances, and view transaction history.

Overview

The budgets client manages per-grant spending budgets. Allocate budgets when issuing grants, debit as agents consume resources, check remaining balances, and review transaction history.

Access the budgets client via client.budgets.

Allocate

Allocate a spending budget for a grant. Threshold alerts are automatically triggered at 50% and 80% consumption.

from grantex import Grantex, AllocateBudgetParams

with Grantex(api_key="gx_live_...") as client:
    allocation = client.budgets.allocate(AllocateBudgetParams(
        grant_id="grnt_01HXYZ...",
        initial_budget=1000,
    ))

    print(f"Budget ID: {allocation.id}")
    print(f"Grant ID: {allocation.grant_id}")
    print(f"Initial: {allocation.initial_budget}")
    print(f"Remaining: {allocation.remaining_budget}")
    print(f"Created: {allocation.created_at}")

AllocateBudgetParams

Parameter	Type	Required	Description
grant_id	str	Yes	The grant ID to allocate a budget for.
initial_budget	int | float	Yes	The initial budget amount. Must be positive.

BudgetAllocation

Field	Type	Description
id	str	Unique budget allocation identifier.
grant_id	str	The associated grant ID.
initial_budget	float	The original allocated budget amount.
remaining_budget	float	The current remaining budget amount.
created_at	str	ISO 8601 timestamp when the allocation was created.

Debit

Debit an amount from a grant’s budget. Uses atomic operations to prevent overdraft. Raises a GrantexApiError with status 402 and code INSUFFICIENT_BUDGET if the balance is insufficient.

from grantex import Grantex, DebitBudgetParams

with Grantex(api_key="gx_live_...") as client:
    result = client.budgets.debit(DebitBudgetParams(
        grant_id="grnt_01HXYZ...",
        amount=50,
        description="GPT-4 API call",
    ))

    print(f"Remaining: {result.remaining}")
    print(f"Transaction ID: {result.transaction_id}")

DebitBudgetParams

Parameter	Type	Required	Description
grant_id	str	Yes	The grant ID to debit from.
amount	int | float	Yes	The amount to debit. Must be positive.
description	str | None	No	Optional description for the transaction.

DebitResponse

Field	Type	Description
remaining	float	The remaining budget after the debit.
transaction_id	str	Unique identifier for the transaction.

If the remaining budget is less than the debit amount, a GrantexApiError is raised with HTTP status 402 and code INSUFFICIENT_BUDGET. Debits are all-or-nothing — no partial debits.

Balance

Check the current budget balance for a grant.

from grantex import Grantex

with Grantex(api_key="gx_live_...") as client:
    allocation = client.budgets.balance("grnt_01HXYZ...")

    print(f"Initial: {allocation.initial_budget}")
    print(f"Remaining: {allocation.remaining_budget}")
    used = allocation.initial_budget - allocation.remaining_budget
    print(f"Used: {used}")

Parameters

Parameter	Type	Required	Description
grant_id	str	Yes	The grant ID to check the balance for.

Response

Returns a BudgetAllocation — see above for field descriptions.

Transactions

List all transactions for a grant’s budget. Supports pagination.

from grantex import Grantex

with Grantex(api_key="gx_live_...") as client:
    result = client.budgets.transactions("grnt_01HXYZ...", page=1, page_size=50)

    print(f"Total transactions: {result.total}")
    for txn in result.transactions:
        print(f"  {txn.description}: -{txn.amount} (balance: {txn.balance_after})")

Parameters

Parameter	Type	Required	Description
grant_id	str	Yes	The grant ID to list transactions for.
page	int | None	No	Page number for pagination (default: 1).
page_size	int | None	No	Results per page (default: 20, max: 100).

TransactionsResponse

transactions	list[BudgetTransaction]	List of transaction records.
total	int	Total number of transactions for this grant.

BudgetTransaction

Field	Type	Description
id	str	Unique transaction identifier.
amount	float	The debited amount.
description	str | None	Optional description.
created_at	str	ISO 8601 timestamp of the transaction.
balance_after	float	Remaining budget after this transaction.

from grantex import Grantex, AllocateBudgetParams, DebitBudgetParams

with Grantex(api_key="gx_live_...") as client:
    # Allocate a budget for a grant
    allocation = client.budgets.allocate(AllocateBudgetParams(
        grant_id="grnt_01HXYZ...",
        initial_budget=500,
    ))
    print(f"Budget allocated: {allocation.initial_budget}")

    # Debit as the agent uses resources
    debit = client.budgets.debit(DebitBudgetParams(
        grant_id="grnt_01HXYZ...",
        amount=25,
        description="Document analysis",
    ))
    print(f"Remaining: {debit.remaining}")

    # Check the current balance
    balance = client.budgets.balance("grnt_01HXYZ...")
    print(f"{balance.remaining_budget} / {balance.initial_budget} remaining")

    # Review transaction history
    result = client.budgets.transactions("grnt_01HXYZ...")
    print(f"{result.total} transaction(s)")
    for txn in result.transactions:
        print(f"  {txn.description}: -{txn.amount} (balance: {txn.balance_after})")
