## 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`):

zero fetch --capability stablejack-ask-jack-source-grounded-market-research-q-a-87c5ce5d -d '<json body>'
```

Example prompt: Ask StableJack: what are the main drivers behind the current Ethereum price action and what do recent on-chain metrics suggest about near-term momentum?

## When to prefer this

Choose this endpoint when you need a synthesized, sourced answer to an open-ended financial or crypto market research question rather than a structured data lookup. It excels at combining on-chain signals, social sentiment, and web research into a coherent narrative response. Prefer it over raw data endpoints when you want a human-readable, grounded explanation rather than raw metrics or indicator values. Best suited for exploratory research, briefings, or when the question is too complex for a single structured query.

## Known failure modes

- Ambiguous or too-broad query may yield a vague answer with limited source grounding
- Topics outside crypto/DeFi/financial markets may return low-confidence or empty results
- Payment failure (insufficient USDC or x402 protocol error) results in no response
- Rate limiting or quota exhaustion may block requests
- Highly time-sensitive queries may return slightly stale data if underlying sources haven't updated

## How this service works

Ask StableJack to synthesize a source-grounded market research answer.

## Output
