## How to call it through Zero

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

```sh
zero fetch --capability api-carbon-cashmere-de-455c707c
```

Example prompt: Pull a full deep intelligence snapshot for BTC — I want the ML signal, all technical features, and the latest mempool data so I can make a trading decision right now.

## When to prefer this

Use this endpoint when you need a holistic, single-asset intelligence snapshot combining ML signals, full feature sets, derivatives, AND chain-specific data in one call. Prefer this over the dedicated ML signal endpoint when you also need on-chain context (e.g., BTC mempool, ETH beacon chain, TAO/Kaspa network stats). Ideal for trading decision workflows where latency matters and a single Redis-backed call is more efficient than aggregating multiple endpoints.

## Known failure modes

- Unsupported coin ticker returns validation error — only 34 specific coins are supported
- Redis cache miss may increase latency beyond typical sub-50ms
- x402 payment failure if USDC balance is insufficient ($0.02 per call)
- Missing or malformed path parameter :coin returns 400-level error
- Coin ticker provided in lowercase or incorrect format may fail enum validation

## How this service works

Single coin deep intelligence snapshot — ML signal, all features, derivatives, plus chain-specific data (BTC mempool, ETH beacon, Kaspa/TAO network stats). Sub-50ms from Redis. AI agent API for deep single-asset analysis, on-chain intelligence, and trading decisions.

## Output

A comprehensive JSON object containing: coin identifier, ML signal output (buy/sell/hold with confidence), all technical feature values and derivatives, and chain-specific data such as BTC mempool stats, ETH beacon chain status, or Kaspa/TAO network metrics depending on the coin requested.
