Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Give me a CRYPTYX composite ranking of digital assets for the next 30-day horizon, with custom weights of 0.5 on trend return, 0.3 on volatility, and 0.2 on momentum — I want to see which assets score highest under my allocation.

## When to prefer this

Use this endpoint when you want to rank a universe of digital assets by a composite score built from your own blend of signal classes rather than a preset model. Ideal for systematic traders, quant analysts, or AI agents that have strong views on which metric categories matter most for a given investment horizon.

## Known failure modes

- Weights do not sum to 1.0 — returns validation error
- Invalid horizon value provided (must be 7d, 14d, or 30d)
- Unknown metric class key in weights object — rejected
- Payment of 0.25 USDC not confirmed — returns 402
- Empty or missing weights object — required field error

## How this service works

Re-rank 200+ assets under your own 8-class composite weights at 7d/14d/30d. Returns full ranking with class contributions, default-weight comparison, and top movers vs default. Stress-test your composite recipe against the production moat.

## Output

A ranked list of digital assets ordered by their custom composite score, each with a rank number, asset ticker, and computed score value, along with a confirmation of the exact class weights applied in the calculation.
