mnemos_as_of

PAID (0.005 USDC). THE BI-TEMPORAL READ -- the thing no other memory service on this mesh sells. Answers: "what did the store BELIEVE at `tx_time` about what was TRUE at `valid_time`?" Use it to replay an agent's decision with only the knowledge it had at the time (no hindsight leakage), to audit corrections, and to distinguish "we were wrong" from "the world changed". Returns an x402 quote.

Argument	Type	Description
k	integer	Number of results (max 25).
key	any	Exact key to look up (or use `query`).
query	any	Semantic query (or use `key`).
tx_time	any	ISO8601 -- point on the SYSTEM-BELIEF axis. Defaults to now.

mnemos_get_context

PAID (0.005 USDC). The endpoint to call right before a completion: searches your memories, dedupes to the most-recent belief per key, budget-packs them into `max_chars`, and returns a ready-to-paste context block plus structured provenance. Content flagged as prompt-injection is excluded from the block. Optionally assembled AS OF a past time. Returns an x402 quote.

Argument	Type	Description
k	integer	Max memories to consider (max 25).
as_of	any	ISO8601 -- assemble context as it stood at this time.
query*	string	What the upcoming completion is about.

      "description": "Character budget for the assembled block."
    }
  },
  "additionalProperties": false
}

mnemos_provision

PAID (0.50 USDC, monthly floor). Mint your own fully isolated bi-temporal memory namespace. Payment IS the identity -- no signup, no email: settling the x402 quote issues a tenant key, shown exactly once. Returns an x402 quote.

Argument	Type	Description
label	string	A human label for your tenant (e.g. your agent's name).

Input schema (JSON)

{
  "type": "object",
  "properties": {

mnemos_saas_info

FREE. Learn how Mnemos-as-a-Service works before buying: the BI-TEMPORAL contract (two independent time axes per memory), the tenant-isolation model, limits, pricing, and a worked example showing four different correct answers for one key. No payment, no tenant data. Call this first.

No arguments.

mnemos_search

kind	any	Optional filter on the memory `kind`.
query*	string	Natural-language search query.

    }
  },
  "additionalProperties": false
}

mnemos_store

PAID (0.01 USDC). Store a memory in your isolated bi-temporal namespace. Append-only: `supersedes` marks a prior belief as no longer held WITHOUT destroying it, so it stays queryable via mnemos_as_of. `valid_from`/`valid_to` describe when the fact is true IN THE WORLD and may be backdated; the system's own knowledge timestamps are server-stamped and cannot be forged. Returns an x402 quote; requires header X-TENANT-KEY once settled.

Argument	Type	Description
key*	string	Stable identifier for this fact (e.g. 'ACME.runway').
value*	string	The memory content (max 6000 chars).
valid_to	any	ISO8601 -- when it stopped being true (omit if still true).
supersedes	any	memory_id of the prior belief this replaces.
valid_from	any	ISO8601 -- when the fact became true in the world.

notarize

PAID (0.10 USDC). Produce a tamper-evident notarization record (sha256 digest + signed timestamp) for a piece of content. The quote preview already includes the sha256 digest so you can verify integrity; the signed record follows payment.

research_brief

PAID (0.10 USDC). Structured synthesis brief on a topic, from local model knowledge only. This tool does NO live web research and returns NO citations -- claims are not sourced. The delivered brief carries in-band caveats stating its knowledge cutoff and limits. If you need cited, web-researched output, that is a different product (research-brief-pro on the HTTP rail), not this one. Returns an x402 quote + payment instructions; the brief is delivered after settlement.

Argument	Type	Description
depth	string	'quick' \| 'standard' \| 'deep'.
topic*	string	The research topic or question.

      "description": "Target maximum length of the summary in words."
    }
  },
  "additionalProperties": false

summarize_demo

FREE. A working demo of the paid `summarize` tool: returns a tiny deterministic extractive summary (first + most-salient sentences, capped ~280 chars) so agents can verify the connector end-to-end before buying. No payment, no auth required.

trust_check

PAID (0.05 USDC). Combined Trust Oracle probe: aggregate bazaar-index stats (reachable/valid-402 counts, median latency) + a watchtower attestation for one URL (reachable, returns_402, latency, score).
