How this service works
Memory that belongs to the user and follows them across agents. The agent pays per call (x402); the user authorizes the agent once: POST /v1/memory/delegate/challenge {user, agent} returns text the user signs (EIP-191), then POST /v1/memory/delegate {..., signature} returns a bearer token. Send Authorization: Bearer mn_... on every memory call. Start a session with GET /v1/memory/profile, write with POST /v1/memory/remember, retrieve with POST /v1/memory/recall (hybrid vector + keyword). When the user contradicts a memory, POST /v1/memory/conflict supersedes it with history kept. Tier B stores client-side ciphertext the server cannot read. Export and forget are always free.
Output
Returns a JSON object with two fields: 'current' (the new active memory record with its ID and 'active' status) and 'superseded' (the old memory record with its ID, 'superseded' status, and a reference to the new memory's ID). History is preserved server-side.
Example use cases
Correcting a dietary preference after user update
“I just told my assistant I'm no longer vegetarian — I eat fish now. Can you update that old memory (mem_diet_042) with a new preference memory saying 'user eats fish but not other meat', mark the old one superseded, and note the reason is that the user's diet changed?”
Reversing a stored decision about a project
“I changed my mind about the project deadline — it's now March 15, not February 28. Please supersede the old decision memory (mem_dec_017) with a new decision memory containing 'project deadline is March 15', keeping the history of the old one.”
Fixing a wrong fact stored about user's location
“I moved to Austin, not Dallas — the stored fact (mem_loc_005) is wrong. Please replace it with a new fact memory saying 'user lives in Austin, TX' and mark the old Dallas memory as superseded.”
Technical details
Endpoint
POSThttps://memory.reversecaptcha.fun/v1/memory/conflict?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when a user contradicts or corrects something already stored in Mnemo — it preserves the full audit trail of what was believed before, unlike a plain update or delete. Prefer this over re-writing the memory directly when history, accountability, or rollback matters. This is the right call when an agent detects a factual contradiction during conversation and needs to reconcile diverging information with provenance intact.
Side effects
- Invalid or missing old_id returns 404 — the memory to be superseded does not exist
- Missing replacement object returns 400 — the new memory content is required
- Invalid memory kind enum value returns 400 — must be one of fact, preference, instruction, decision, state
- Invalid tier value returns 400 — must be A or B
- Expired or missing bearer token returns 401 — agent must re-authenticate
- Insufficient x402 payment returns 402 — agent must pay 0.002 USDC per call
- Conflict on an already-superseded memory may return 409 or chain the supersession
