Endpoint
GEThttps://hars.cryptotavern.xyz/paid/reseller/aggregated-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a ready-made, aggregated intelligence snapshot of Polymarket prediction markets without building Polymarket API integrations yourself. It is especially useful for agents that operate autonomously and can pay per-call in USDC via the x402 protocol, requiring minimal setup. Prefer it over raw Polymarket APIs when you want a summarised, agent-optimised brief rather than raw data.
Side effects
- Payment not included or insufficient USDC via x402 protocol — returns 402 Payment Required
- No markets match the given filter properties — returns count:0 and empty markets array
- Service unavailable or upstream Polymarket data disruption — returns 5xx error
- Malformed request properties — returns 4xx validation error
