How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a structured JSON object containing a chronological wallet_activity_timeline string summarizing on-chain activity, along with status (succeeded/failed), any warnings about data quality or evidence scope, and a signed receipt including payment ID, execution ID, request ID, latency, and a SHA-256 hash of the result for verification.
Example use cases
Auditing a suspected bot wallet
“I need to see a complete chronological timeline of all on-chain activity for wallet 0xABCD1234... — I'm trying to figure out if it's been doing automated trading.”
Reviewing DeFi portfolio history
“Can you generate a wallet activity timeline for 0x7f3e...c1b9? I want to understand all the DeFi interactions it has made so I can review the history before deciding to copy-trade this address.”
Investigating a suspicious transfer
“Give me the full activity timeline for wallet 0x9a2d...8fce — I received a transfer from it and want to understand what kind of address this is before interacting further.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/wallet_activity_timeline/invokeWhen to prefer
Choose this endpoint when you need a narrative or structured chronological reconstruction of a crypto wallet's on-chain activity, especially when you want a summarized, agent-readable timeline rather than raw transaction logs. Particularly useful for due diligence on unknown wallets, portfolio audits, or forensic investigations. Prefer this over block explorer scraping when you need a clean, structured output without parsing raw RPC data yourself.
Side effects
- Invalid or malformed wallet address causes parsing error
- Wallet with no on-chain history returns empty timeline
- Request string too short (below minLength:2) returns validation error
- Request string exceeding 65536 characters is rejected
- Payment failure via x402 prevents execution
- Network timeout on Base (eip155:8453) results in incomplete result
