How this service works
NFT Alpha: OpenSea NFT market signals for one or many currently watched OpenSea collection slugs. Body: { collection: string } or { collections: string[] }; omit the body to query all watched collections. Returns listing/sale/bid counts, price stats, sell-through, and signals such as HIGH_DEMAND, UNDERPRICED_LISTING, BID_FRENZY, DUMP_WARNING, LOW_DEMAND. NFT Alpha OpenSea market signals for NFT listings, sales, bids, floor price, and bid frenzy. Not financial advice.
Output
A structured response containing listing count, sale count, bid count, floor price, sell-through rate, and one or more categorical market signals such as HIGH_DEMAND, UNDERPRICED_LISTING, BID_FRENZY, DUMP_WARNING, or LOW_DEMAND for the requested OpenSea collection(s).
Example use cases
Example prompt
“What are the current NFT Alpha market signals for pudgypenguins on OpenSea — is there high demand, bid frenzy, any dump warnings, and what does the floor price and sell-through look like right now?”
Technical details
Endpoint
POSThttps://nft-alpha-x402.fly.dev/api/nft-signalWhen to prefer
Use this endpoint when you need real-time NFT market intelligence for OpenSea collections, specifically the categorical signals (HIGH_DEMAND, BID_FRENZY, DUMP_WARNING, UNDERPRICED_LISTING, LOW_DEMAND) alongside raw listing/sale/bid counts and floor price stats. Prefer this over general NFT APIs when you want pre-computed demand signals rather than raw data, and when you need to evaluate up to 10 collections in a single call for comparative analysis.
Side effects
- Invalid or unknown collection slug returns an error or empty signal set
- Collection has insufficient data for signal generation, resulting in LOW_DEMAND or null signals
- Batch request exceeds 10 collections and is rejected
- Payment of $0.05 USDC not provided or fails, resulting in 402 Payment Required
- OpenSea data unavailable or rate-limited upstream, causing a service error
