# NFT Collection Intelligence — Floor, Volume, Liquidity & Market Health

> NFT Collection Intelligence — Floor, Volume, Liquidity & Market Health is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-11).

Fetches and computes comprehensive NFT collection metrics including floor price (native + USD), market cap, volume, holder counts, liquidity ratio, sales velocity, floor momentum, and a normalized market-health verdict across EVM chains (via CoinGecko) and Solana/Bitcoin Ordinals (via Magic Eden).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nft-collection-intelligence-floor-volume-liquidity-market-health-7ca4a61e
```

Example prompt: Give me a full market health analysis for the Bored Ape Yacht Club NFT collection on Ethereum — I want the floor price in ETH and USD, liquidity ratio, sales velocity, holder count, and your confidence-rated verdict on whether the collection is healthy right now.

## When to prefer this

Use this endpoint when you need a single unified call that combines raw NFT collection data (floor, volume, supply, holders) with pre-computed market intelligence metrics (liquidity ratio, sales velocity, floor momentum, health verdict). Prefer this over raw blockchain RPC calls or separate CoinGecko/Magic Eden queries when you need cross-chain coverage and computed analytics in one response without managing multiple API keys.

## Known failure modes

- Unknown slug or contract address returns 404 or empty result
- Chain mismatch between slug type and provided chain parameter causes lookup failure
- EVM contract address provided without specifying chain may default incorrectly
- CoinGecko or Magic Eden upstream API downtime causes 503 or stale data
- Bitcoin Ordinals collections only available via Magic Eden; providing EVM slug with chain=bitcoin will fail
- Missing required 'slug' or 'contract' parameter causes 400 validation error

## How this service works

Flagship NFT collection intelligence: fuses identity, floor (native+USD), market cap, volume, total supply, holders and listed count into COMPUTED metrics — liquidity ratio (listed/supply + volume/mcap), holder/supply ratio, sales velocity and floor momentum — plus a normalized market-health verdict with confidence and rationale. EVM via CoinGecko, Solana + Bitcoin-Ordinals via Magic Eden. Keyless, attributed.

## Output

Returns a structured object with: collection identity metadata, floor price in native token and USD, market cap, 24h/7d volume, total supply, holder count, listed count, plus computed metrics — liquidity ratio (listed/supply + volume/mcap), holder/supply ratio, sales velocity, floor momentum — and a normalized market-health verdict with a confidence score and plain-English rationale.
