Paste a Composer.trade symphony URL and get its node count, with a breakdown of where the nodes come from. Composer does not show this number in the platform, and it is the number the pricing tiers are counted against.
A symphony URL like https://app.composer.trade/symphony/4aI4kVT5cEc0XJpTLei3/details,
a bare ID, or raw JSON from the /score endpoint.
The count runs higher than most people expect, because an asset counts every time it appears. A filter or a weighting block over six tickers is six asset nodes plus the block itself, and reusing that same set inside several IF branches counts it again each time.
