How this service works
describe.net over MCP (Streamable HTTP), stateless: the same global ERC-8004 reputation index as fourteen tools. Eight of them never charge — including `describe_check_wallet`, which tells you whether a wallet has anything worth paying for, and `describe_resolve`, which tells you what a bare string even IS (wallet, agent id, or both at once) before you pay to look one up on the wrong chain. The metered tools relay the x402 402 of the route behind them; `accepts` below is the cheapest of those, $0.01. No account, no API key: paying is the authentication.
Output
Returns structured reputation data from the ERC-8004 global index: for free tools, this includes entity type classification (wallet, agent ID, or both) and a pre-flight signal on whether the wallet has paid-lookup-worthy reputation data. For metered tools (starting at $0.01 USDC), returns reputation scores, rater counts, and index ranking data. Payments are handled via x402 protocol; no API key required.
Example use cases
Pre-flight trust check before payment
“I'm about to pay 0x4a3b...f7c2 for some work — can you check their describe.net reputation score and tell me if they have enough on-chain ratings to be worth trusting before I send anything?”
Resolve ambiguous identifier before chain lookup
“I have the string 'nova-agent-7' and I don't know if it's a wallet address, an ERC-8004 agent ID, or both — can you resolve it on describe.net so I know which chain and lookup to use?”
Vet an AI agent before delegating a task
“I want to delegate a research task to an agent I found, their address is 0x9f1a...b3d8 — can you pull their ERC-8004 reputation from describe.net and tell me their score and how many distinct raters they have?”
Technical details
Endpoint
POSThttps://api.describe.net/mcpWhen to prefer
Choose this endpoint when you need on-chain ERC-8004 reputation data for wallets or agent identities and want a no-account, no-API-key approach where payment is authentication. Prefer this over generic blockchain explorers when you specifically need reputation scores and rater metrics rather than raw transaction history. The free pre-flight tools (describe_check_wallet, describe_resolve) make this especially valuable when you need to avoid paying to look up an entity on the wrong chain or with no reputation data.
Side effects
- 402 Payment Required if metered tool called without sufficient x402 payment
- Unresolvable string if identifier does not match any known wallet or agent ID on any supported chain
- Chain mismatch if wallet looked up on wrong chain before using describe_resolve first
- Empty reputation data if wallet has no ERC-8004 ratings recorded
- Timeout if underlying chain RPC is slow or unavailable
