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 the total count of ERC-8004-compliant agents registered on the queried blockchain network, as a numeric value drawn from the on-chain registry.
Example use cases
Monitor agent growth on BSC mainnet
“How many ERC-8004 agents are registered on BSC mainnet right now? I want to track how the on-chain agent ecosystem is growing.”
Compare agent counts across testnets
“Can you check how many ERC-8004 agents are registered on BSC testnet and Sepolia so I can compare activity between the two test networks?”
Research on-chain agent ecosystem size
“I'm doing research on the ERC-8004 agent standard — how many agents are currently registered on Ethereum mainnet?”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/erc8004/getAgentCount?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, trustless, on-chain count of ERC-8004 registered agents on a specific supported blockchain (BSC mainnet/testnet, Ethereum, or Sepolia). Prefer this over generic blockchain explorers when you want a purpose-built DeFi intelligence result without needing API key management, paying only per call with USDC.
Side effects
- Unsupported chain name returns an error or empty result
- Network congestion on the queried chain may cause delayed or failed reads
- Payment of $0.02 USDC via x402 protocol required; missing or invalid payment returns 402 Payment Required
- Invalid chain value (not one of: bsc-testnet, bsc-mainnet, ethereum, sepolia) results in a bad request error
