## When to prefer this

Choose this endpoint when you need on-chain NFT holder data across any of 46 supported blockchains and want pay-per-request pricing via x402 without a subscription. Ideal for agents needing real-time holder snapshots for airdrop targeting, governance analysis, or community analytics.

## Known failure modes

- Invalid or non-existent contract address returns 404 or empty result
- Unsupported chain identifier returns an error
- Contract is not an NFT contract (e.g. ERC-20) may return error or empty
- Payment failure (x402) if USDC balance insufficient
- Rate limiting if called too frequently
- Network timeout for large collections with many holders
