Read citation evidence

get_citation_evidence Read one retained citation answer envelope and verify its exact content hash. Expired bodies return410; the hash does not prove an independent timestamp or provider authenticity.

Available in the deployed MCP and HTTP bundle. Confirm access and inputs with your connected catalog. Workspace scopes and enabled providers still apply.

Access	Behavior
`watches:read`	Reads saved data

This read does not start a verification job.

Example request

Connect through MCP, CLI, or HTTP. Replace example identifiers with records from your workspace.

Returned result

Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in structuredContent and in a text content block; generic HTTP and CLI return the JSON result directly.

Input fields

Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.

Field	Type	Presence	Meaning and constraints
`observationId`	string	Required	ID of a saved observation; this does not fetch a new publisher page. minLength: 1; maxLength: 200

Validation and omitted values

Recomputes the retained body digest before returning it. An expired body returns410; metadata and its digest may remain. Screenshot retained is always false in this release.

Output fields

Fields inside optional or nullable parents apply only when that parent exists. Common schema conventions explain evidence states, empty lists and extensions.

Errors and retries

The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict. See error recovery for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.

HTTP resource routes

This operation has no separate resource alias. Use its generic command route in a matching environment.
