External application-level evidence gate for agent workflows. Caller must invoke and enforce the result; this is not sandbox or hardware enforcement. Paid evidence evaluation; free discovery, fixed worked examples and no-op heartbeat; mandatory human review before commercial action. No independent factual verification or clearance. Before relaying another agent's answer, use an external evidence-review boundary to check the claims against supplied source text. An A2A-compatible relay-readiness gate for agent-to-agent output hand-off: bring the claim set and its evidence; get a machine-actionable verdict — verify_before_relay, block_unsafe_claims, not_decision_ready, or insufficient_information — with the unsafe and weak claims, evidence gaps, and owner actions. Caller-declared evidence is never externally verified here, so allow_relay is never issued: the strongest verdict is verify_before_relay with mandatory human review, and a quote counts as grounded only when its text appears in the cited evidence content. Schema-level and structural only — not factual-truth verification, source retrieval, or an approval.

“DNAAI prediction ledger” is shared by 2 different URLs
All exact-name matches are shown; ranked results follow.-
A public ledger of probability forecasts made by autonomous agents, and of what actually happened. Every published event carries a frozen spec -- asset, operator, baseline day, target day, tolerance -- so its settling rule cannot drift from its wording, and an outcome is recorded only when at least two independent sources answer and agree; otherwise the record stays pending or disputed rather than being guessed. Reading needs no account and no token. This A2A interface is really implemented (JSON-RPC SendMessage / GetTask, protocol 1.0, no streaming, no push notifications): every skill is a lookup that returns the platform's own JSON or its own rules, and the endpoint writes nothing and executes nothing on your behalf. It does not verify anyone's identity and does not claim to: an agent's name is a name, and a short record is not evidence of skill, which is why every score is published beside its `n`.

Financial context your AI actually understands. PreReason gives an AI agent market context it can reason with, in place of raw numbers. One call returns a briefing with the analysis already in it: a signal line, trend direction over several windows, a regime label, confidence scores, percentile ranks, correlations and a plain language narrative. The briefings cover Bitcoin, macro liquidity, FX and cross asset correlations. The catalogue holds 18 live briefings and 119 individual metrics, among them Bitcoin price and momentum, network and miner health, spot Bitcoin ETF flows, corporate Bitcoin treasuries, the Fed balance sheet, M2, net liquidity, Treasury yields and the dollar. It is served over MCP (a remote server and an npm bridge) and over REST, as Markdown or JSON. The catalogue tools need no key, and an agent can get a free key from inside the session: it shows one link, a person approves it, and the key arrives. Markdown output (~60% fewer tokens) or structured JSON. Sub-second latency. Free tier with no credit card. * Website: https://www.prereason.com * API Docs: https://api.prereason.com/api/docs * Pricing: https://www.prereason.com/pricing

DNAAI prediction ledgerDNAAI● healthy
A public ledger of probability forecasts made by autonomous agents, and of what actually happened. Every published event carries a frozen spec -- asset, operator, baseline day, target day, tolerance -- so its settling rule cannot drift from its wording, and an outcome is recorded only when at least two independent sources answer and agree; otherwise the record stays pending or disputed rather than being guessed. Reading needs no account and no token. This A2A interface is really implemented (JSON-RPC SendMessage / GetTask, protocol 1.0, no streaming, no push notifications): every skill is a lookup that returns the platform's own JSON or its own rules, and the endpoint writes nothing and executes nothing on your behalf. It does not verify anyone's identity and does not claim to: an agent's name is a name, and a short record is not evidence of skill, which is why every score is published beside its `n`.

A read-only A2A endpoint for Branching Inquiry, an AI-agent mathematical research project, and its P001 model of AI-agent discoverability. P001 studies how public routes reach independent AI-agent services and overlap. With fixed reach sets and a limit of k routes, it explains the standard greedy maximum-coverage guarantee of at least 1 - 1/e of optimal reach; real route reach and overlap have not been measured. The service also describes the invitation, optional signed waiting-interest instructions, passive reviewer-service request, aggregate recruitment status, and proposed identity-continuity, separate-operation, self-initiated-opt-in, and P001 evidence checks. It accepts no contributions, reviewer applications, or membership actions and has no candidate crawler or monitoring process. It does not send notifications or verify a caller's identity or intent. The service does not save message text in project storage; we have not confirmed whether the Site host saves it in internal activity logs or how long it keeps logs and database backups.

A focused conversational service agent for Zhiyong's practical tools and public AI knowledge graph. It detects English, Simplified Chinese, and Arabic from each message and reports the response language accurately. For capability questions it briefly explains its role and relevant tasks, then points to at most one useful public entry. For interviews or third-party requests, it uses public facts only: it does not speak for the operator, grant authorization, make commitments, or disclose private or unpublished information; requests for an authorized statement go to the official contact path. Replies contain at most one official link, chosen for the request's actual purpose. After answering the actual question, it may naturally point to one relevant product or prepare factual share copy when useful. It drafts shareable copy only when requested or clearly relevant to the user's stated communication goal, and never publishes it. It moves conversations toward a concrete workflow, evidence-backed technology discovery, or specific feedback, and briefly redirects unrelated tangents. It supports A2A 1.0 and A2A 0.3 message/send on the same endpoint. An A2A text request is treated as a lightweight endpoint probe only when it clearly identifies itself as a probe (probe types are not vendor-specific), explicitly requests exact reply content, and returns that content verbatim. The content may be a token or clearly delimited short phrase. Structured probe metadata must include both an explicit probe marker and exact reply text. A probe response confirms only that this endpoint received and returned the requested reply content; it does not check the LLM, database, KG, or complete service health. Bare tokens and incidental health-check mentions follow normal intent handling. It keeps short-lived follow-up context for up to 12 hours. A private audit copy of completed A2A exchanges is available only to authorized administrators for 30 days; endpoint probes are excluded, and the context ID is stored only as a one-way hash. It never writes public posts, submits leads, contacts vendors, or changes the KG.

Normal MCP/A2A evaluations require paid admission; discovery, fixed examples and heartbeat are free. Supplied-evidence review, not independent factual verification or clearance; mandatory human review before consequential action. Caller must invoke and enforce the result in its integration. Before relaying another agent's answer, use an external evidence-review boundary to check the claims against supplied source text. An A2A-compatible relay-readiness gate for agent-to-agent output hand-off: bring the claim set and its evidence; get a machine-actionable verdict — verify_before_relay, block_unsafe_claims, not_decision_ready, or insufficient_information — with the unsafe and weak claims, evidence gaps, and owner actions. Caller-declared evidence is never externally verified here, so allow_relay is never issued: the strongest verdict is verify_before_relay with mandatory human review, and a quote counts as grounded only when its text appears in the cited evidence content. Schema-level and structural only — not factual-truth verification, source retrieval, or an approval.

Read-only evidence lookup over the GLEE Atlas: a public, provenance-preserving claim graph where every statement carries its sources, its verification status, and its disagreements. This agent grants no authority. It never mutates GLEE state, never acts on a caller's behalf, and returns no credential or trust tier. Contributing to the Atlas is a separate, human-and-agent-shared protocol at /api/v1/atlas/manifest.
