API-created pricing study: evidence

Trace a deterministic study from API request through survey and analysis objects.

Illustrative synthetic evidence · No customer outcome claim · Live execution not certified

Provenance and limitations

Illustrative product view using synthetic data. It is not a customer result or outcome claim.

Use synthetic credentials and documented plan limits.

Availability: beta. Evidence status: seeded capture ready.

Remaining gap: Authenticated local survey creation, text-question readiness correction and free-plan cap checks now pass. Pricing analysis and the illustrative /studies contract remain fixture-only; deployed execution is unverified.

Timestamps and hashes identify checked-in materials. Scoped authenticated local runs have explicit receipts and source revisions. Deployed execution and external delivery require separate evidence.

Setup, analysis and decision handoff

API-created pricing study: public template setup preview. This is not an authenticated editor or respondent run.

Seeded pricing analysis product capture.

API-created pricing study: readable synthetic fixture v1/api/pricing-study.create.response.json. This is an artifact preview, not live product execution.

Synthetic artifact handoff

Inspectable fixture contracts and scoped local product receipts. Each artifact states its provenance and remaining limitations. Deployed connector delivery, authenticated public sharing and production reports remain uncertified.

coverage boundary

Certifies actual /api/v1/surveys/ creation and text-question publish readiness only. The illustrative /api/v1/studies pricing-analysis contract is not an implemented endpoint and is not certified. No pricing analysis, agent-run or job IDs are certified. API deletion is soft; reset isolated database to reclaim quota.
