Get a month's fee summary
/v1/me/transaction-fees/summary in the Transaction Fees API.
curl "https://api.subscriby.net/v1/me/transaction-fees/summary?month=2026-10" \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN"Adds up one calendar month, the current one when month is left out. total_fee is every line; at_source_fee is what Stripe Connect deducted from members' payments and never invoiced; metered_fee is what reached the usage meter, the figure to hold against that month's Transaction Fees line on your Subscriby invoice, split into invoiced_fee (a paid invoice has collected it) and awaiting_invoice_fee (it lands on the next one). by_kind lists the month per kind of fee, by_project per project largest first (the fees no project carries pool under a null id), and invoices the Subscriby invoices that billed the month's metered lines. Pass project_id to add up one project alone; by_project is then empty.

MCP tool

Query Parameters
The calendar month to add up, as YYYY-MM in UTC, such as 2026-10; the current month when left out.
Add up one project's lines alone; every project when left out, in which case the per-project shares are returned too.
uuidResponses
200OKapplication/json
The month's totals per channel, kind, project and invoice.
401UnauthorizedAUTHENTICATION_REQUIREDapplication/json
The request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an sbt_test_ token on production).
403ForbiddenTOKEN_MISSING_ABILITYapplication/json
The token is valid but does not carry the ability this endpoint requires; error.context.required_ability names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers FORBIDDEN, TEAM_TIER_REQUIRED or CONNECTOR_TIER_REQUIRED with the same status, and says so in its own description.
422Validation failedVALIDATION_FAILEDapplication/json
The payload broke a rule, and error.fields maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with error.message saying why and no fields.
On this endpoint: VALIDATION_FAILED: when month is not YYYY-MM or project_id is not an id.
429Too many requestsRATE_LIMITEDapplication/json
The token has spent its 300 requests a minute or 10,000 an hour; Retry-After says when the next one is accepted.

Every event Subscriby posts to one of your webhook endpoints is a delivery: one row per endpoint per event, carrying the signed envelope that was sent, the target's response and where the row is on the retry ladder.
