Tokens ranked by how fast agent attention is speeding up — query velocity change across three consecutive windows, overlaid with price change over the same window. Divergence classes: early_signal (attention accelerating, price flat), confirmed_momentum, distribution_risk (attention cooling while price pumps), fading. Proprietary: derived from SolEnrich's own agent query stream, not market volume.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
