How this service works
The daily history of one agent record: dealings, independent payers, concentration and delivery over time.
Output
A time-series dataset of daily records for the specified agent address, each record containing dealings count, number of independent payers, concentration score, and delivery metrics for that day.
Example use cases
Audit agent payment payer diversity
“Pull up the daily history for agent 0xDef456... and show me how many independent payers they've had each day over the past month.”
Track agent delivery trends over time
“I need to see how delivery activity has changed over time for the agent at address 0x789Ghi... — can you fetch their full historical record?”
Monitor agent concentration changes
“Can you get the historical concentration data for the agent at 0xJkl012... so I can see if it's been getting more or less concentrated in its dealings over time?”

Endpoint
GEThttps://aspern.org/api/v1/agents/:address/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to analyze the historical behavior, payer diversity, concentration, or delivery patterns of a specific on-chain agent over time. Prefer this over real-time endpoints when you need trend data or time-series analytics rather than a current snapshot.
Side effects
- Invalid or malformed agent address returns an error or empty result
- Agent address with no history returns an empty array
- Rate limiting or payment failure (x402 payment not accepted) blocks the request
- Non-existent agent address returns 404 or empty response
