Returns up to 20 projects per page in ID order; use next_cursor with the same month. Current unresolved reservations are separate from measured consumption. Null environment_id means project-shared cost, never guessed Dev allocation. Only posted measurements are included; this is not a complete provider invoice or zero-usage guarantee. Billing may arrive later. No credit is granted or charged by this read; it remains usable at zero credits. ## OpenAPI ````yaml /openapi.json get /v1/organizations/{organization_id}/credit-usage openapi: 3.1.2 info: title: ohmyho.st API version: 0.0.0 description: >- Public REST API for ohmyho.st hosting, projects, domains, email, credits and exports. servers: - url: https://app.ohmyho.st description: Production control API - url: https://dev.app.ohmyho.st description: Development control API security: - BearerAuth: [] paths: /v1/organizations/{organization_id}/credit-usage: get: summary: Read monthly measured usage by project and meter description: >- Owner-only event-month ledger totals, including signed corrections posted by as_of.
