Include a reference date in extraction prompts

You can opt in to an advanced extraction setting that adds a fixed “current date” line to the system prompt. The model can use it when a field depends on today, relative phrases like “30 days from now”, or ambiguous short dates on the page (for example interpreting 02/03/26). The value is taken from when the run was created in UTC.

The option is off by default. For API version 2026-02-09, set advancedOptions.currentDateEnabled to true. See the JSON Schema extraction guide for how advanced options fit into your setup.

Detailed credit breakdown on run responses

Run objects now include richer usage metadata so you can see how credits relate to underlying work alongside the billed amount (credits). The existing usage.credits value is unchanged. For full run payloads and webhook events, responses can also include totalCredits, representing all contributing charges for that logical run (for example extraction plus parsing when parsing was billed for that run), and a breakdown array listing each contributing resource type, id, and credit amount.

On list endpoints, summaries include credits and totalCredits but omit breakdown to keep payloads small. Runs written before totalCredits and breakdown were stored may expose only credits; treat totalCredits and breakdown as optional. For background on billing units, see How credits work. For the full object shape, see usage on the extract run response.
