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. While a large dataset version's training tokens are first counted, it answers 503 tokens_counting with Retry-After: ask again then. ## OpenAPI ````yaml /openapi.json post /v1/families/{family}/continue/estimate openapi: 3.1.0 info: title: OneHot API description: >- Decisions your application can act on: send a context and the questions you want answered, and get a probability for every answer you allow. Authenticate with `Authorization: Bearer onehot_sk_...`. A short guide for coding agents is at /llms.txt. An API key reads its account but never changes it: keys, billing and settings change in the console. Money fields ending in _usd are exact decimal strings, never integer cents. Over a rate limit a request gets 429 with Retry-After, and one with more input tokens than your minute allows gets 422 too_many_tokens. version: 0.1.0 servers: - url: https://api.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.
