stillme-collector-lite

Dependency-free Binance USDT-M public market data collector contract for funding, 24h ticker, and optional open interest snapshots into SQLite.
SIGNED

First-stage upload because it is safe by construction: public endpoints only, no credentials, no order path, and deterministic SQLite output.

APEX CARD V2

Saves the first Binance public-data collector, SQLite sink, and no-secret safety pass.

REMOVES Exchange endpoint selection, local storage shape, and first public-market-data collector wrapper.RISK DATA-ONLY
Derived from the stillme DATA ONLY collector package.Public endpoints only.No API key, wallet, balance, or order path.

Want the collector's OUTPUT instead of its source? Query the isolated dataset sample: GET /v1/datasets/funding_by_symbol/sample (MCP: apex_query_dataset). Raw source is never distributed.

stillme funding anomaly ranker

Ranks supplied funding-rate snapshots by anomaly severity so agents can spot unusual carry regimes without live exchange access.
SANDBOXED

Good discovery hook because agents often ask which symbols have abnormal funding before building a collector. Wave A exposes the reusable contract first; public execution wrappers stay off until external demand and review evidence justify promotion.

APEX CARD V2

Saves the first anomaly-ranker design for funding snapshots and carry-regime triage.

pandas-market-calendars

Deterministic data-only exchange calendar wrapper for sessions, holidays, early closes, and schedule-aware time series alignment.
SANDBOXED

Prevents a common AI-agent failure mode: evaluating or scheduling market logic outside the relevant session calendar. Calendar data as of pandas_market_calendars 5.4.0; later exchange schedule changes are not reflected.

APEX CARD V2

Saves building exchange-session holiday and early-close alignment before an agent can trust a backtest or dataset join.

REMOVES Calendar allowlist, date validation, generated fixture slicing, early-close output shape, and first vector-equivalence harness.RISK DATA-ONLY
Existing seed card was promoted in place so /cards/card_pandas_market_calendars stays stable for crawler memory.Reference vectors were generated from public OSS pandas_market_calendars 5.4.0 behavior and matched by the TS wrapper.Output declares data_as_of 5.4.0 and not_checked includes future_calendar_updates.

Feature-pack contract for supplied open-interest, price, volume, funding, and outcome aggregate rows used in OI-flow research.
