AggViz
FREE Alternative data, no signup

Free alternative data — and the tools to find the signal.

AggViz pulls real data straight from live APIs — clinical trials, vessel traffic, market indices — then finds the model that fits, compares the field, and shows you what's actually predictive.

The data

Real datasets, pulled live from the source.

Connect to alternative-data APIs and work with what's actually moving. Free to start — and if the data you need isn't here, we'll get it.

Clinical trials

Live registries — phases, sponsors, endpoints and status changes. Track a pipeline or a whole therapeutic area.

Free · live APIClinicalTrials.gov ↗

AIS / vessel traffic

Free AIS feed — positions, speed, draught and port calls for the global fleet. Build congestion, flow and ETA signals.

Free · live APIaisstream.io ↗

Metals — ferrous & non-ferrous

Steel, copper, aluminium, nickel and precious metals — spot and historical prices for industrial and macro signals.

Free tier · APIcommodities-api ↗

Markets & indices

Economic series, index levels and reference data — the benchmark you're trying to beat, aligned to your alt-data.

Free · live APIFRED ↗

Economic & trade

GDP, inflation, trade, labour and energy across 200+ economies — World Bank, Eurostat and Data.gov, open and licence-free.

Weather & climate

Historical and live meteorological series — temperature, precipitation, wind — for demand, agriculture and logistics models.

How it works

From a live feed to a model that holds up.

You bring the question. AggViz handles the plumbing, the model search, and the proof.

01

Pull the data

Pick a source and load it from the API — or bring your own CSV. Millions of rows, no cleanup ritual.

02

The wizard reads it

It profiles target, features and scale, then reasons about which model family actually fits.

03

Train & compare

It runs a slate of candidates under honest cross-validation and ranks them — evidence, not a guess.

04

See the signal

Every run returns the plots that matter — importances, errors, correlations. See why it works.

AggViz MCP

Pull the data into your agent.

AggViz ships an MCP server, so Claude and other agents can fetch the alt-data you need and render the visualisations — without leaving the chat.

  • Query any connected source by name and filter
  • Get structured tables back, ready to model
  • Render charts and comparisons inline
agent · aggviz-mcp
# add the AggViz MCP server
$ claude mcp add aggviz https://mcp.aggviz.com

# then, from your agent
› get_dataset("ais", region="north-sea")
  → 1.4M rows · 18 cols
› compare_models(target="port_eta")
