How this service works
Signalbound API for agent metadata, reveal-aware token reads, ERC-8004 registration files, and holder-gated tool routes.
Output
Returns a JSON object containing the feed type, timestamp, total count of drops found, an array of drop objects (each with name, slug, chain, mint stages, image, supply data, OpenSea URL, contract address, and optional wallet eligibility), the authenticated caller address, and a human-readable brief summary of the scan results.
Example use cases
Discover featured drops on Ethereum
“Use my Signalbound token 7 to pull the top 20 featured NFT drops on Ethereum and give me a brief summary of what's launching.”
Multi-chain mint eligibility check
“With my Signalbound token ID 99, scan all chains for up to 15 upcoming NFT drops and check if wallet 0xDEF...456 can mint any of them — include the detailed per-drop data too.”
Recently minted collection scouting
“I want to see what's been recently minted across all chains — use Signalbound token 23 and return up to 30 drops, no eligibility check needed.”
Technical details
Endpoint
POSThttps://api.signalbound.art/drop-radar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover active, upcoming, or recently minted NFT drops sourced from OpenSea with optional real-time wallet eligibility probing, and you hold a Signalbound token for access. It is especially useful for agents that need structured, multi-chain drop intelligence with per-drop supply and stage data in a single call rather than scraping OpenSea manually.
Side effects
- Token ownership check fails — caller does not own the specified Signalbound token ID, returning a 401/403 auth error
- Invalid or unsupported chain filter string returns empty results or an error
- OpenSea API unavailability causes incomplete or empty drop lists
- Wallet eligibility check fails if the mint-build API is unavailable for a specific drop
- Very high limit values may cause slow responses or timeouts when enrich is also enabled
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| type | string | Drop feed to scan. Defaults to all, which combines OpenSea featured, upcoming, and recently minted surfaces. |
| chain | string | Optional chain filter (e.g. ethereum, base, polygon). Omit for all chains. |
| limit | integer | Maximum drops to return (default 20). |
| enrich | boolean | Fetch extra per-drop detail data when needed (default false). The radar uses OpenSea list-stage data by default for faster scans. |
| tokenIdrequired | integer | Signalbound token ID used for ERC-7496 clearance-gated access. The authenticated caller must own it. |
| scanChains | boolean | When true, radar also queries known OpenSea chains individually to catch drops that do not appear in the unfiltered feed (default true). |
| walletAddress | string | Optional wallet for eligibility checks. Defaults to the SIWE-authenticated caller address. |
| checkWalletEligibility | boolean | When true, uses walletAddress (or the authenticated caller) to probe mint eligibility via OpenSea mint-build API. |
