Technical details
Endpoint
GEThttps://api.8k4protocol.com/agents/21480/scoreWhen to prefer
Use this endpoint when you need a standardized ERC-8004 trust score for a specific agent on a particular blockchain chain, especially when you need a quick numeric reputation signal before deciding whether to interact with or delegate to an autonomous agent. Prefer this over the explanation endpoint when you only need the raw score, not the reasoning behind it.
Side effects
- Agent ID not found — 404 or empty result
- Invalid chain ID — returns error or no score available
- Agent has no on-chain history — score may be null or zero
- Network or RPC issues causing timeout
- Insufficient USDC balance for x402 payment — request rejected
