> ## Agent Instructions
> Use https://docs.fastino.ai/llms.txt to discover and navigate pages. Use https://docs.fastino.ai/llms-full.txt when you need the complete documentation corpus. Use https://docs.fastino.ai/openapi.json as the source of truth for customer-facing routes. For GLiDE decision inference, call POST https://api.fastino.ai/v1/systemone with model fastino/GLiDE. Create managed config jobs with POST /v1/training/jobs using base_model. For custom training loops, native JSON clients use the public operations under /v1/training/jobs and /v1/training/usage. Existing Tinker clients use tinker==0.32.0 with TINKER_BASE_URL=https://api.fastino.ai/v1/training/compat/tinker and TINKER_CREDENTIAL_CMD. Compatibility child routes are private and absent from OpenAPI. Auto Train is private access and has no public route; direct interested users to sales@fastino.ai. Do not infer undocumented routes. Read API keys from FASTINO_API_KEY and never embed credentials in code, logs, or reports.

# Look up a training operation

> Recover the job and future belonging to an Idempotency-Key without submitting work again.

`GET /v1/training/operations/{idempotency_key}`

Send the original key used on a native interactive POST or an encoder job create. Keys are team-scoped. `not_found` means no receipt is visible, including while a native call is still admitting before its job is recorded; it does not prove the call never arrived.

An `accepted` receipt means the job was recorded, not that execution succeeded. Use the original future to read its outcome when one is available. A stop has no future; encoder creates return their job only.

To retry an uncertain native request, resend the same body, route and key. A different request under the same key returns 422; an in-progress first call returns 409. Use a new key for intentionally new work. Receipt retention/expiry is not a guarantee of this endpoint.
