How this service works
Signalbound API for agent metadata, reveal-aware token reads, ERC-8004 registration files, and holder-gated tool routes.
Output
A JSON object containing the token's name, rarity tier (e.g. common/rare/legendary), numeric rarity score, trait map (key-value pairs), a brief agent-readable description, edition label, and the caller's address if holder-gated access applies.
Example use cases
NFT rarity research for trading
“What's the rarity tier and rarity score for Signalbound token 1337? I want to know if it's worth picking up.”
Agent-readable trait inspection
“Pull the metadata for Signalbound token 88 — I need all its traits and what edition it belongs to.”
Portfolio intelligence summary
“Get me the intel brief for Signalbound token 2048, including its name and rarity tier, so I can decide whether to list it.”
Technical details
Endpoint
POSThttps://api.signalbound.art/intel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, agent-ready intelligence for a specific Signalbound NFT token — including reveal-aware metadata, rarity scoring, and trait breakdown. Prefer this over generic NFT metadata APIs when working specifically with the Signalbound collection (token IDs 1–6666) and needing ERC-8004-compatible or holder-gated data.
Side effects
- Invalid tokenId outside range 1-6666 returns an error
- Unrevealed token may return limited or placeholder metadata if reveal has not occurred
- Payment failure via x402 returns 402 status blocking access
- Missing required tokenId field returns a 400 validation error
- Holder-gated routes return restricted data if caller does not hold the token
