Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/nft-floorWhen to prefer
Use this endpoint when you need a quick, cheap ($0.01) floor price lookup for a specific Base NFT collection contract and only need the minimum listing price from OpenSea or LooksRare. Prefer this over broader NFT analytics APIs when you just need the floor figure for Base-native collections without full market depth or historical data.
Side effects
- Collection contract address not listed on any supported marketplace — returns empty or null floor price
- Invalid or non-Base contract address — returns error or no data
- Collection not indexed by Alchemy — no coverage
- Payment not completed (402 returned) — agent must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Network or relay downtime — 5xx error from relai.fi
