Nothing is queued or held. The estimate is exact if nothing changes before you start; pass it as max_price_usd to cap the price. ## OpenAPI ````yaml /openapi.json post /v1/families/{family}/continue/estimate openapi: 3.1.0 info: title: DecisionOne workbench description: >- Native decisions, versioned datasets, adaptation and shared-base deployment. Authenticate with `Authorization: Bearer d1_sk_...` when accounts are on. A short guide for coding agents is at /llms.txt. Hosted account APIs accept a Bearer API key or a browser session. An API key reads its account but can't change it: keys, billing and settings change in the console. Browser mutations require the configured Origin and X-CSRF-Token from /auth/session. Account recovery and history remain available to blocked accounts. Waitlisted accounts can read their account summary and model catalogue and request early access; private member APIs require admission. Money fields ending in _usd are exact decimal strings; never interpret them as integer cents. Authenticated customer reads and existing-operation replays share read_rpm, and other customer writes except decisions and their estimates share write_rpm. Exhausted budgets return 429 with Retry-After; unavailable admission storage returns 503. version: 0.1.0 servers: - url: https://console.sqwish.ai security: [] tags: - name: Decisions description: Probabilities for questions with fixed outcomes. - name: Models description: Base models, and fine-tuned models by their numbers. - name: Families description: >- Lines of models trained on one dataset, and the switches that let them answer calls. - name: Datasets description: >- Validated training examples.
