UnstableEvaluationRules 5
POST
/api/public/unstable/evaluation-rules
Create an evaluation rule. An evaluation rule defines what incoming data should be evaluated and how prompt variables should be populated from that data. Use this resource after choosing an evaluator…
unstable_evaluationRules_create body → 200400401403404405409422
GET
/api/public/unstable/evaluation-rules
List evaluation rules in the authenticated project. Each item describes one live evaluation rule and its effective runtime status.
unstable_evaluationRules_list 2 params → 200400401403404405429500
GET
/api/public/unstable/evaluation-rules/{evaluationRuleId}
Get one evaluation rule by its identifier. Use this endpoint to inspect the current evaluator, target, mapping, filters, and effective runtime status.
unstable_evaluationRules_get 1 param → 200400401403404405429500
PATCH
/api/public/unstable/evaluation-rules/{evaluationRuleId}
Update an evaluation rule. Typical uses: - enable or disable live execution - switch to another evaluator - adjust sampling - change filters - update variable mappings Important behavior: - provide o…
unstable_evaluationRules_update 1 param body → 200400401403404405422429
DELETE
/api/public/unstable/evaluation-rules/{evaluationRuleId}
Delete an evaluation rule. This removes the live-ingestion rule only. It does not delete the referenced evaluator.
unstable_evaluationRules_delete 1 param → 200400401403404405429500

Schemas 34

The contract defines 34 schemas that model the data the API accepts and returns. The most detailed are unstablePublicApiErrorDetails (15 properties), unstableEvaluationRule (13 properties), unstableCreateEvaluationRuleRequest (7 properties), unstableUpdateEvaluationRuleRequest (7 properties). Each schema is shown below with its type and property counts.

Where this information came from

This is an independent, third-party profile of Langfuse UnstableEvaluationRules API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
