Evidence research for a factual claim or article URL.

Submit a claim as text or paste an article URL. URLs are auto-detected and trigger article mode: the pipeline extracts claims from the page and auto-selects up to 5 for evidence research.

Tiers (in fallback order):

• lookup (~£0.02, instant) — cached prior analysis

• consensus (~£0.03, instant) — cross-user aggregate landscape (k≥3 checks)

• quick (~£0.07, ~15s) — web search + heuristic classification

• full (~£0.15, ~60-90s) — 30+ sources, LLM classification, coverage recovery

Charges based on tier actually executed, not tier requested. Set max_tier to control maximum spend per call.

Output structure:

• claims[].claimMap.elements[] — verifiable sub-claims with state (supported/disputed/unresolved)

• claims[].claimMap.elements[].evidenceRefs[] — evidence mapped to elements with relationship (supports/challenges/context) and reasoning

• claims[].evidence[] — sources classified by tier (primary/reporting/ commentary) and type (data/official/news/analysis/opinion/academic)

• claims[].claimMap.orientation — mechanical summary from element states

• _meta — execution metadata: executedTier, chargedPence, limitations

Args: claim: A factual claim ("The Earth's average temperature rose 1.1°C since 1880") or an article URL (https://example.com/article). URLs are auto-detected and the pipeline extracts claims from the page content. max_tier: Maximum tier to attempt — "lookup", "consensus", "quick" (default), or "full". max_age_hours: Skip cache hits older than this many hours. If set, lookup hits that are stale will be discarded and the pipeline re-runs at the next tier up to max_tier. compact: If True, strip full evidence arrays from response (smaller payload).

Retrieve a previously submitted check with pre-computed analytics.

Returns the full result including a _computed block with tier/type distributions, corroboration groups, diagnostic values, timeline analysis, element state summaries, and per-claim dispositions.

Use this over tru8_get_result_raw when you want structured analytics ready for summarisation or comparison without post-processing.

Args: check_id: UUID returned by tru8_check.

Retrieve a previously submitted check without computed analytics.

Returns claims, elements, evidence, and claim maps only. No _computed block. Smaller response payload. Use this when you will compute your own aggregations or only need specific fields from the raw data.

Args: check_id: UUID returned by tru8_check.
