x402
SignalHarness NFT Trait Distribution Analyzer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Analyzes and returns the trait distribution breakdown for a given NFT collection or set of NFTs based on caller-supplied data.

How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object with the trait distribution results (keyed as 'nft_trait_distribution'), any warnings about data quality or scope, evidence scope indicator ('caller_supplied_data'), and a detailed execution receipt including payment ID, network, amount, latency, and a SHA-256 hash of the result for verification. Status field indicates whether the computation succeeded.
Example use cases
NFT rarity analysis for a new drop
“I just minted a new NFT collection and want to understand how the traits are distributed — can you analyze the trait data and show me how often each attribute appears across all the tokens?”
Pre-launch trait balance check
“Before we launch our NFT project, can you run a trait distribution analysis on our metadata to see if any traits are over- or under-represented compared to the rest of the collection?”
Collector research on existing collection
“I'm thinking of buying into this NFT collection — can you analyze the trait distribution from this collection data and tell me which traits are the rarest and which are most common?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/nft_trait_distribution/invokeWhen to prefer
Choose this endpoint when you need to compute trait frequency and distribution statistics specifically from caller-supplied NFT metadata or collection data, particularly within an agent-native, micropayment-based (x402) workflow on Base. It is best suited for on-demand, per-call NFT trait analytics without requiring API key management, using USDC micropayments at $0.01 per call.
Side effects
- Invalid or malformed nft_trait_request string causing parsing failure
- Input below minimum length (2 chars) or above maximum (65536 chars) rejected with validation error
- Empty or unrecognizable NFT metadata yields warnings with partial or empty distribution output
- Payment failure via x402 protocol resulting in 402 response and no computation
- Service timeout returning an error status instead of 'succeeded'
