Retrieve usage history

GET
/v1/usage/history
curl --fail-with-body -X GET 'https://api.talki.it/v1/usage/history?from=2026-05&to=2026-10&location_id=0b7d4e19-8a2c-4f61-9d3e-5c1a7b2f8e40' \
  -H "Authorization: Bearer $TALKI_API_KEY"

Return the talk time billed in each calendar month, up to 13 months, oldest first. A call counts, whole, in the month it was answered in. With location_id, only the calls of that location count. Requires account:read. Limited to 600 requests per minute per account (API key) or per installation (OAuth).

Query Parameters

Section titled “Query Parameters”
from
Any of:
string

First month, YYYY-MM. Default: 12 months before to.

to
Any of:
string

Last month, included, YYYY-MM. Default: the current month, which is still counting. Not after the current month. At most 13 months from from.

location_id
Any of:
string

Only the calls of this location (Call.location_id), an id from GET /v1/locations (inactive ones included). Omit for every location. Each call belongs to one location, so the locations’ months add up to the account’s.

Header Parameters

Section titled “Header Parameters”
Talki-Version
string
Example
2026-10-01

Serve this one request at the given dated contract version instead of the credential’s pin. An unsupported value is refused with 400 unsupported_version, never downgraded.

Successful Response

Media typeapplication/json
UsageHistory

Talk time per calendar month, oldest first, from the call log. A call counts in the month it was answered in. A month is not a billing period, and the meter of GET /v1/usage adds a call once it has ended, so the current month can differ from it, and a call running past midnight into a new month counts here in the earlier one. A month reads less than was billed when some of its calls were deleted, through DELETE /v1/calls/{call_id} or in the apps, or are before retained_since. With location_id, only that location’s calls count; the locations’ months add up to the account’s.

object
months
required
Months

One entry per month asked for, oldest first.

Array<object>
UsageMonth

Talk time billed in one calendar month, in the account’s timezone.

object
month
required
Month

The month, YYYY-MM, in the account’s timezone.

string
start
required
Start

Local midnight on its 1st, RFC 3339 UTC.

string format: date-time
end
required
End

Local midnight on the next month’s 1st, RFC 3339 UTC, excluded.

string format: date-time
used_seconds
required
Used Seconds

Talk time billed for the calls answered in the month that are still in the call log: the sum of their duration_seconds. A deleted call is no longer counted, though its time stays billed. Zero for a month with no calls.

integer
calls
required
Calls

Calls answered in the month that billed time and are still in the call log.

integer
retained_since
required
Retained Since

Calls older than this, RFC 3339 UTC, have been deleted by Talki’s retention, so a month before it reads less than was billed.
