Use this chart via API

On the Max plan you can pull this chart's numbers with the provenance of each one, as JSON or CSV, with its redraw spec, or call it from an agent over MCP. Chart id 50ebc452b7d1.

Approximate values. Our two readings of this chart agreed only in part (confidence 0.34 of 1), so check the original before you quote a number. The API marks it lowConfidence, and ?min_confidence=0.5 leaves it out.

Questions people ask

How accurate are these numbers?

They are estimated from the image by two independent passes, with confidence 0.34 on a 0 to 1 scale. Printed numbers read well; values read off an axis can be a few percent off.

Can I reuse this data?

The numbers describe a chart that artificial-analysis published. The image, layout and styling belong to them. Use the numbers with a credit to the publisher, and make your picture from your own data.

How do I get the file?

The JSON, CSV and agent skill file are under the email gate on this page. In this prototype they are static files at /api/charts/50ebc452b7d1.json and /api/charts/50ebc452b7d1.skill.md.
