## How to call it through Zero

zero fetch --capability losbeto-thesis-engine-91e800ff

Example prompt: Can you pull an AI-generated investment thesis for Solana from the Losbeto thesis engine? I want to see the swarm's current rationale and market analysis for it.

## When to prefer this

Choose this endpoint when you need an AI-generated investment thesis or trading rationale for a crypto asset, specifically from a multi-chain (Solana + Base) AI trading swarm context with USDC micropayment access. Prefer it over generic LLM-based financial analysis when you want a specialized, swarm-aggregated thesis signal with a structured JSON output.

## Known failure modes

- Missing or malformed 'properties' parameter returns an error or empty thesis
- Insufficient USDC balance (x402 payment failure) blocks the request
- Ambiguous or unsupported asset query may return a generic or null thesis
- Rate limiting or swarm unavailability returns a service error
- Malformed JSON response if the thesis engine encounters an internal error
