x402
agent402.tools Memory Audit Log is a paid API for AI agents from agent402.tools, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Retrieves a tamper-evident, hash-chained append-only audit log of all changes to a memory namespace, with optional filtering by owner address and entry count.

How this service works
Tamper-evident history of every change to a namespace - an append-only, hash-chained audit log the server attests to (provenance an agent can't forge for itself). ?owner=0x… reads a granted namespace.
Output
Returns an ordered list of up to 1000 audit log entries representing every change ever made to the namespace, each cryptographically linked to the previous via a hash chain. The server attests to the log, making it unforgeable by the agent itself. Each entry records the change, its timestamp, and the hash linking it to prior entries.
Example use cases
Example prompt
“Pull the last 200 entries from the tamper-evident memory audit log for namespace 0x1a2b3c4d5e6f7890abcdef1234567890abcdef12 so I can verify what changes were made and that the history hasn't been forged.”
Technical details
Endpoint
GEThttps://agent402.tools/api/memory/logWhen to prefer
Use this endpoint when an AI agent needs verifiable, unforgeable provenance of all changes to a memory namespace — especially when a third party must trust that the history has not been tampered with. Prefer this over generic logging solutions when cryptographic hash-chaining and server attestation are required, or when auditing agent behavior for compliance or dispute resolution.
Side effects
- Missing or invalid 0x owner address returns an authorization error — the namespace requires a valid grant
- Limit parameter outside 1–1000 range may return a validation error or be clamped to defaults
- An ungranted namespace returns an access-denied or empty response
- Network or payment failure (x402 protocol) results in no data returned
- If the namespace has no history, an empty log array is returned
