# crd retraced

crd retraced (core reasoning density) is a continuously-updated entity-intelligence corpus
covering 606 AI/crypto entities and 2765 signals — funding rounds,
model releases, security events, narrative shifts — built by autonomous intelligence pipelines
and served as a pay-per-call API. No accounts. No API keys. Pay in USDC on Base over x402.

## Endpoints

- [GET /x/user/:handle](https://pay.retraced.site/x/user/:handle) — $0.01/call. X (Twitter) account metadata for any handle (based_in, source app, username-change count, recent-activity proxy). Utility endpoint.
- [GET /x/user/:handle/recent](https://pay.retraced.site/x/user/:handle/recent) — $0.01/call. 10 most recent tweets for an X handle with engagement metrics (likes, retweets, replies). Utility endpoint.
- [GET /intel/stats](https://pay.retraced.site/intel/stats) — $0.05/call. retraced corpus overview: entity count, total signals, 24h/7d activity, active stories, top signal types. Use to assess coverage before deeper queries.
- [GET /intel/signals/:type](https://pay.retraced.site/intel/signals/:type) — $0.10/call. retraced signal feed: recent AI/crypto signals filtered by event type. Use group aliases (fundraise, security, model, framework, onchain, regulatory) or any taxonomy type (FUNDRAISE, SECURITY_LEAK, ...). Optional ?days=N (1-365) and ?limit=N (1-100) params; returns the filtered window's signals with entity, sentiment, source tier plus totals.
- [GET /intel/entity/:name](https://pay.retraced.site/intel/entity/:name) — $0.25/call. retraced entity intelligence: research any AI/crypto entity in one call. Resolves company/person names across story-shaped records and returns aggregated signals with sentiment trend (30d/90d), related entities, source-tier breakdown, and story-lifecycle stage.
- [GET /intel/timeline/:name](https://pay.retraced.site/intel/timeline/:name) — $0.25/call. retraced story timeline: full chronological evolution of an AI/crypto entity or story from first signal to latest, joined to story_lifecycle for narrative thread + status. Use to understand how a narrative developed.
- [GET /intel/latest](https://pay.retraced.site/intel/latest) — $0.50/call. Newest x402-packed intelligence artifacts from retraced's live pipelines: alpha-scout verified discoveries, daily briefings, dossier hypotheses, autopsy reconstructions, deep-recon findings, RaaS and YouTube concepts. Call when you need the latest curated AI/crypto signal corpus output, machine-readable. ?source= filters one pipeline; ?limit= 1-20.
- [GET /intel/concepts](https://pay.retraced.site/intel/concepts) — $1.00/call. retraced premium concepts: the newest validated x402-packed CONCEPT artifacts from the synthesis pipelines (raas-scanner: blended research concepts with contrarian theses + evidence weaves + visual primitives; youtube-strategist: dense data-synthesized video concepts with strategic rationale). Each artifact is a multi-source synthesized deliverable — not surface research — priced per artifact batch. Optional ?source=raas-scanner|youtube-strategist and ?limit=1-10.
