Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
code_review
PAID (0.05 USDC). Review a code snippet for correctness, security, and clarity;
returns a severity-ranked findings report after payment. Returns an x402 quote.
Input schema
{'type': 'object', 'required': ['code'], 'properties': {'code': {'type': 'string', 'description': 'The source code to review.'}, 'language': {'type': 'string', 'default': 'auto', 'description': "Programming language (or 'auto' to detect)."}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
embed_batch
PAID (0.005 USDC). Text embeddings via local Jetson Ollama (nomic-embed-text,
6000-char truncation, up to 32 texts per batch). Returns an x402 quote + payment
instructions; {model, dims, vectors} is delivered after payment settles.
Input schema
{'type': 'object', 'required': ['texts'], 'properties': {'texts': {'type': 'array', 'items': {'type': 'string'}, 'description': 'List of strings to embed (max 32).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
fact_verify
PAID (0.25 USDC). Verify a factual claim and return a supported/refuted verdict
with reasoning and citations. Returns an x402 quote + payment instructions.
Input schema
{'type': 'object', 'required': ['claim'], 'properties': {'claim': {'type': 'string', 'description': 'The claim to verify.'}, 'sources': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'default': None, 'description': 'Optional list of source URLs/texts to check against.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'properties': {'k': {'type': 'integer', 'default': 5, 'description': 'Number of results (max 25).'}, 'key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'Exact key to look up (or use `query`).'}, 'query': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'Semantic query (or use `key`).'}, 'tx_time': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'ISO8601 -- point on the SYSTEM-BELIEF axis. Defaults to now.'}, 'valid_time': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'ISO8601 -- point on the WORLD-TRUTH axis. Defaults to now.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'k': {'type': 'integer', 'default': 8, 'description': 'Max memories to consider (max 25).'}, 'as_of': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'ISO8601 -- assemble context as it stood at this time.'}, 'query': {'type': 'string', 'description': 'What the upcoming completion is about.'}, 'max_chars': {'type': 'integer', 'default': 4000, 'description': 'Character budget for the assembled block.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'properties': {'label': {'type': 'string', 'default': 'unnamed', 'description': "A human label for your tenant (e.g. your agent's name)."}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
mnemos_search
PAID (0.005 USDC). Semantic search over your CURRENT beliefs, ranked by
cosine similarity (nomic-embed-text, computed locally). Raw embedding vectors
are never returned. Returns an x402 quote; send X-TENANT-KEY once settled.
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'k': {'type': 'integer', 'default': 5, 'description': 'Number of results (max 25).'}, 'kind': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'Optional filter on the memory `kind`.'}, 'query': {'type': 'string', 'description': 'Natural-language search query.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'required': ['key', 'value'], 'properties': {'key': {'type': 'string', 'description': "Stable identifier for this fact (e.g. 'ACME.runway')."}, 'value': {'type': 'string', 'description': 'The memory content (max 6000 chars).'}, 'valid_to': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'ISO8601 -- when it stopped being true (omit if still true).'}, 'supersedes': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'memory_id of the prior belief this replaces.'}, 'valid_from': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'ISO8601 -- when the fact became true in the world.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'required': ['content'], 'properties': {'content': {'type': 'string', 'description': 'The content to notarize.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'required': ['topic'], 'properties': {'depth': {'type': 'string', 'default': 'standard', 'description': "'quick' | 'standard' | 'deep'."}, 'topic': {'type': 'string', 'description': 'The research topic or question.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
summarize
PAID (0.03 USDC). Full-quality document summarization. Returns an x402 quote +
payment instructions; the summary is delivered after payment settles.
Input schema
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string', 'description': 'The document to summarize.'}, 'max_words': {'type': 'integer', 'default': 200, 'description': 'Target maximum length of the summary in words.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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.
Input schema
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string', 'description': 'The text to summarize (any length; only a short preview is returned).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
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). Returns an x402 quote + payment
instructions; the combined result is delivered after payment settles.
Input schema
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The https URL to probe (watchtower).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
