## How to call it through Zero

```sh
zero fetch --capability losbeto-thesis-engine-f272b7bc
```

Example prompt: Can you pull an investment thesis from the Losbeto thesis engine for the current market conditions — I want a structured AI-generated trading argument I can review before making a move?

## When to prefer this

Choose this endpoint when you need an AI-generated, structured investment thesis or trading argument delivered programmatically and are comfortable paying $0.69 USDC per call via x402 on Solana or Base. It is part of a large swarm of 67 monetized endpoints, so prefer it when your agent workflow requires thesis-style analytical narrative rather than raw price data or order execution.

## Known failure modes

- Missing or malformed 'properties' input parameter returns an error or empty response
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Endpoint may time out if the AI swarm is under load
- Vague or empty properties input may yield a generic or low-quality thesis
- Network issues on Solana or Base settlement layer could delay payment confirmation

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.
