Endpoint
GEThttps://markets.losbeto.xyz/api/v1/best?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover which specific Losbeto endpoint is most relevant for a given task before committing to a purchase. It acts as a paid catalog concierge — ideal for agents that don't know the full Losbeto catalog and want semantic routing guidance with pricing and payment metadata in one call.
Side effects
- Missing required 'task' query parameter returns catalog overview instead of a ranked recommendation
- Vague or ambiguous task strings may produce low-confidence matches
- Payment via x402 required — no payment means 402 response and no data
- Endpoint catalog may not cover niche or very new asset classes
- Network or blockchain payment confirmation delays may cause latency spikes
