Example prompt
“Can you pull the list of token holders for the ERC-20 contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum so I can see how the supply is distributed?”
Technical details
Endpoint
POSThttps://x402.onchainexpat.com/api/x402-crypto/token-holdersWhen to prefer
Use this endpoint when you need on-chain token holder data for a specific token contract and want pay-per-use pricing via the x402 protocol without a subscription. Prefer this over traditional blockchain data APIs when operating in an agent context that supports x402 micropayments.
Side effects
- Invalid or unrecognized contract address returns an error or empty result
- Unsupported blockchain network not indexed by the provider
- Payment not processed correctly via x402 protocol resulting in 402 response
- Rate limiting or quota exceeded
- Token contract exists but has no indexed holder data yet
