Records a user interaction signal (e.g. welcomed or annoyed by an assumed memory) to update the agent's clarification tolerance model for that user

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 an updated observation count (integer) and a recalculated clarification tolerance score (float 0–1) reflecting how much the user tolerates agent assumptions vs. prefers explicit clarifying questions.
Example use cases
Adapting after unwanted assumption
“The user just got annoyed when I assumed they wanted the formal tone again — log that as 'assumed_and_annoyed' in Mnemo so I start asking before assuming next time.”
Reinforcing welcomed proactive questions
“The user actually seemed happy I asked before proceeding — record 'asked_and_welcomed' in Mnemo so it knows I should keep checking in with this person.”
Tracking silent acceptance of assumption
“I assumed the user wanted metric units and they didn't object at all — send 'assumed_and_accepted' to Mnemo so it can factor that into my clarification tolerance score for them.”
Technical details
Endpoint
POSThttps://memory.reversecaptcha.fun/v1/memory/observe?utm_source=zero.xyzWhen to prefer
Use this endpoint after any interaction where the user's reaction to an assumption or clarifying question is observable — it is specifically designed to build a behavioral tolerance model unique to Mnemo's portable cross-agent memory system, unlike generic memory stores that lack structured interaction signal tracking.
Side effects
- Invalid signal enum value returns a 422 validation error
- Missing or expired bearer token returns 401 unauthorized
- Payment not settled via x402 returns 402 payment required
- User delegation not established returns 403 forbidden
- Service unavailable returns 503 with retry guidance
