Why it moved
Spend rose 38% because key ci-agents switched to Opus on
Tuesday. That is 71% of the increase.
AI spend, stitched together
Every AI dollar, accounted for.
Costura turns the bills from every AI provider into one story: where the money went, why it moved, and which key nobody owns, before it shows up on the invoice.
Needs a person
Key sk-...ab12 has no owner and no spend limit. It spent
$140 in the last 30 days.
Numbers you can trust
September 1 to 14 against August 1 to 14. Same days, same providers, matched to the invoice.
One story across providers
Anthropic, OpenAI, OpenRouter, Cursor and GitHub Copilot in a single ledger.
Every key accounted for
Owner, limit, creation date and last use for each key, seat and account.
Your keys stay with you
Open source and self-hosted. Admin keys never leave your infrastructure.
