How this service works
Pay-per-call on-chain investigation API (x402, USDC on Base).
Output
A natural language investigation summary answering the submitted question, covering on-chain facts such as deployer identity, wallet transaction history, token movements, and behavioral patterns, along with a unique request_id for the call.
Example use cases
Token deployer rug pull check
“Who deployed this token at 0xabc123 and have they sold all their holdings? I want to know if this looks like a rug pull before I buy in.”
Whale wallet behavior analysis
“Can you investigate this wallet address 0xdef456 and tell me its on-chain history — where did the funds come from, what tokens has it traded, and does anything look suspicious?”
DeFi protocol liquidity investigation
“What actually happened to the liquidity in the UniSwap pool for this token 0x789xyz — did the team drain it, and which wallets were involved?”

Endpoint
POSThttps://x402.sleuthagent.ai/api/v1/ask-me-anythingWhen to prefer
Choose this endpoint when you need natural language answers to specific on-chain blockchain questions — particularly around token deployers, wallet histories, rug pull detection, and DeFi activity — and are willing to pay $1 USDC per call via x402 on Base. Prefer this over block explorers or raw RPC calls when you want an interpreted, human-readable investigation rather than raw data, and over free analytics APIs when depth and specificity of investigation matter more than cost.
Side effects
- Payment failure if insufficient USDC balance on Base or x402 protocol error
- Ambiguous or unsupported query results in a vague or empty response
- Unknown or very new contract addresses may yield limited on-chain data
- Rate limiting or infrastructure downtime returning 5xx errors
- Malformed question input leading to irrelevant investigation output
