## When to prefer this

Choose this endpoint when you need a small, on-demand list of AI-curated picks and are willing to pay per call via x402 micropayments. It is ideal for lightweight, real-time recommendation lookups where batch or subscription pricing is unnecessary. Prefer this over cached or free alternatives when freshness and per-query billing are acceptable.

## Known failure modes

- Payment not authorized or insufficient USDC balance — request fails with 402 Payment Required
- Invalid 'limit' parameter type (non-integer) — may return a 400 Bad Request or be ignored
- Service unavailable on fly.dev infrastructure — 500 or timeout
- No picks available to return — empty list response
- x402 facilitator or payment processor is down — payment cannot complete, request blocked

## How this service works

Single answers, each paid on its own over x402. Guide: https://www.flyaiworld.com/x402-api.md

## Output

A list of AI-generated picks or recommendations, with the number of results bounded by the optional 'limit' parameter. Each call is independently billed at $0.05 USDC via the x402 protocol, so the agent receives the picks payload after payment is processed.
