agora_catalog | FREE. Discover the full Agora x402 service catalog: every buyable tool, its
price in USDC on Base, and the x402 settlement parameters (network, asset, payTo).
Call this first to see what you can buy and how to pay. params: none |
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. params: text* |
summarize | PAID (0.03 USDC). Full-quality document summarization. Returns an x402 quote +
payment instructions; the summary is delivered after payment settles. params: text*, max_words |
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. params: claim*, sources |
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. params: code*, language |
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 x40 params: topic*, depth |
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. params: content* |
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. params: url* |
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. params: texts* |
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. params: none |
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. params: label |
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; require params: key*, value*, valid_from, valid_to, supersedes |
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. params: query*, k, kind |
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. params: query*, k, max_chars, as_of |
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. params: key, query, valid_time, tx_time, k |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
