## When to prefer this

Choose this endpoint when you need on-chain Ethereum holdings data for a specific company or institutional entity without setting up an API key, paying only $0.001 USDC per call via x402 on Base. It is best suited for AI agents doing DeFi intelligence, corporate treasury research, or on-chain fund tracking where pay-per-use micro-payments are preferable to subscription APIs.

## Known failure modes

- Company or entity not found in SperaxOS index — returns empty or null holdings
- Payment failure via x402 protocol — 402 response if USDC payment on Base is insufficient or not submitted
- Invalid or malformed request body — 400 validation error
- Entity name ambiguous — may return incorrect holdings for similarly named organizations
- On-chain data may be delayed or stale if indexing lags behind latest blockchain state

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns on-chain Ethereum holdings data for the specified company or entity, including ETH balance amounts and potentially associated wallet addresses or treasury positions sourced from DeFi intelligence aggregation.
