Endpoint
GEThttps://hars.cryptotavern.xyz/paid/reseller/curated-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-filtered, editorially curated subset of Polymarket markets rather than raw or unfiltered data. Ideal for AI agents that want high-signal, low-noise prediction market intelligence without building their own curation layer. Best suited for pay-per-call, on-demand use cases where fresh market snapshots matter and micropayment via x402/USDC is acceptable.
Side effects
- Payment not attached or insufficient USDC — returns HTTP 402 requiring x402 payment
- Invalid or malformed properties filter — may return empty markets array
- Service unavailable — upstream Polymarket data outage could result in empty or stale response
- Rate limiting if payment is not processed correctly on Base or Solana chain
