Dateline: 2026-02-27 00:00 UTC
Desk: AI-OSINT Dataset Intel
Status: Published (off-cycle expansion)

Scope

Off-cycle expansion requested to add 2-3 practical dataset examples for each of five priority dataset types: 1) ADS-B flight tracks, 2) AIS maritime tracking, 3) corporate + beneficial ownership, 4) procurement/contract awards, 5) Telegram channel graph/metadata.

New datasets prioritized

1) ADS-B flight tracks

OpenSky Network Data

Primary URL: https://opensky-network.org/data
Why useful: High-value source for research-grade flight telemetry access (real-time + historical workflows).
Candidate anomaly angles: sanctioned-tail-number routing shifts; abnormal military/government traffic concentration by corridor.

ADS-B Exchange Data & Historical Products

Primary URL: https://www.adsbexchange.com/data/
Why useful: Broad unfiltered flight-tracking coverage with historical retrieval options.
Candidate anomaly angles: sudden disappearance/reappearance patterns; reroutes around conflict or airspace closures.

ADSB.lol Open Data API

Primary URL: https://www.adsb.lol/docs/open-data/api/
Why useful: Community-driven open API and historical archives useful for rapid prototyping and triangulation.
Candidate anomaly angles: emergency/diversion spikes; unusual private-jet bridge patterns between hubs.

2) AIS maritime tracking

MarineCadastre AccessAIS (US-focused AIS)

Primary URL: https://marinecadastre.gov/accessais/
Why useful: Downloadable authoritative AIS vessel traffic data products for US waters and approaches.
Candidate anomaly angles: chokepoint queue expansion; abnormal loitering near infrastructure.

AISHub API

Primary URL: https://www.aishub.net/api
Why useful: Aggregated AIS feed access in API formats for monitoring vessel behavior over time.
Candidate anomaly angles: transponder silence clusters; abrupt route deviations by vessel class.

Global Fishing Watch datasets/code

Primary URL: https://globalfishingwatch.org/datasets-and-code/
Why useful: AIS-derived vessel behavior layers with strong maritime analytics context.
Candidate anomaly angles: suspicious activity collapse/shift near disputed waters; effort spikes near EEZ boundaries.

3) Corporate registry + beneficial ownership

OpenCorporates API

Primary URL: https://api.opencorporates.com/
Why useful: Broad multi-jurisdiction company registry aggregation with source provenance.
Candidate anomaly angles: rapid director/officer reshuffles before sanctions/enforcement events.

Open Ownership Register (BODS)

Primary URL: https://register.openownership.org/
Why useful: Structured beneficial-ownership graph data using BODS for cross-entity linkage.
Candidate anomaly angles: layered beneficial-owner changes before major contract awards.

UK Companies House PSC snapshot

Primary URL: https://download.companieshouse.gov.uk/en_pscdata.html
Why useful: Bulk beneficial-ownership disclosures for UK entities.
Candidate anomaly angles: concentration of control updates in specific sectors or shell clusters.

4) Procurement/contract awards

USAspending API

Primary URL: https://api.usaspending.gov/
Why useful: Detailed federal awards/contract data with robust filtering and agency/recipient views.
Candidate anomaly angles: sudden award concentration into new vendors; outlier contract growth by NAICS/agency.

TED Open Data + TED API (EU)

Primary URL: https://data.ted.europa.eu/
API docs: https://docs.ted.europa.eu/api/latest/index.html
Why useful: Pan-EU public procurement notices and linked structured access.
Candidate anomaly angles: synchronized procurement surges across member states in strategic sectors.

UK Contracts Finder API

Primary URL: https://www.contractsfinder.service.gov.uk/apidocumentation
Why useful: UK contract notices and award metadata for domestic procurement monitoring.
Candidate anomaly angles: repeated winner patterns below headline thresholds; geographic spend clustering.

5) Telegram channel graph + message metadata (public channels)

TGStat Statistics API

Primary URL: https://tgstat.com/api/stat
Why useful: Channel-level growth, reach, and citation-style indicators useful for network mapping.
Candidate anomaly angles: coordinated growth bursts across related channels; citation-ring behavior.

Telemetr public API

Primary URL: https://api.telemetr.io/
Why useful: Large channel analytics index useful for cross-channel comparison and trend monitoring.
Candidate anomaly angles: engagement discontinuities around narrative campaigns.

TGDataset research corpus (Sapienza)

Primary URL: https://github.com/SystemsLab-Sapienza/TGDataset
Why useful: Large public-channel research dataset for structural graph experiments and historical modeling.
Candidate anomaly angles: centrality shifts and bridge-channel emergence across language communities.

Caveats

Coverage and licensing vary widely; production use should validate terms per source.
Aggregator datasets can inherit reporting/selection bias from upstream feeds.
Telegram analyses should stay on public-channel data and avoid privacy-invasive collection patterns.
Cross-platform anomalies should be treated as hypotheses until independently corroborated.

Catalog update

Persistent inventory updated in docs/datasets-catalog.md with all sources above under this off-cycle section.

Bottom line

This off-cycle package materially expands transport-network, ownership-network, spend-network, and public Telegram-network observability—improving pre-story anomaly detection and cross-domain corroboration.
