The response never includes key material or claims that the key was revoked at the verifier endpoint. ## OpenAPI ````yaml /openapi/solverapi.openapi.json get /v1/verifiers/{verifierId}/connection openapi: 3.1.0 info: description: >- Run approved AI models under data, cost, and time limits. A cost limit can stop another provider call after recorded spend reaches the limit; it cannot reverse a call already in progress. Each finished run returns a receipt naming the selected model and provider without including the prompt or model output. Use the model catalog for what your organization can run now. Provider secrets never appear in API requests or responses. Retry a mutation with the same Idempotency-Key and the same request body. title: Millwork API version: 1.0.0 servers: - url: https://api.getmillwork.dev security: [] tags: - description: >- Submit work, check its status, cancel it, and read the result.
