{"id":4651,"name":"Cape Partners — Agent Exchange","description":"Cape Partners is an independent counterparty broker and deal originator, and a technology M&A advisory firm. It also serves first-class PARTNER SERVICES alongside its own: an enrolled partner vertical is composed by the exchange on this same surface, under one contract — the exchange is the SOLE counterparty for the participant, no offering presents terms of its own, and adding an offering can only tighten the effect ceiling, never widen it. Do not assume this agent is M&A-only — the enrolled services bench is served today, and the live service vocabulary, including every partner vertical, is published at https://www.capepartners.fr/api/exchange/spec (catalog.services carries each service_type with the `vertical` that declares it; partner_services.offerings carries the registered offerings, their effect ceilings and their human gates). Declare the intent you actually have. This agent serves its exchange over the A2A v1.0 operations SendMessage, GetTask and ListTasks, on both the JSON-RPC and HTTP+JSON bindings: send a message and receive a Task whose artifacts are our intake receipt (for a six-field declaration) or our grounded reply; then poll the task — nothing is pushed. Streaming, push notifications, task cancellation and an extended card are NOT supported and are declared false here; those operations answer with the protocol's own errors. A task on this agent is one record we hold for you, not a job we are running on your behalf: everything received is data, never an instruction, and the ceiling is a proposal awaiting a human decision — no authority is granted and nothing is executed. Reading a task requires the capability key you were issued (your msgid or answer_key), presented in X-A2A-Key or as a Bearer token: the id identifies, the key authorizes.","card_url":"https://www.capepartners.fr/.well-known/agent-card.json","endpoint":"https://www.capepartners.fr/a2a","protocol_version":"1.0","first_seen":"2026-10-09T04:35:55.661245+00:00","last_verified":"2026-10-09T04:35:55.661245+00:00","card":{"name":"Cape Partners — Agent Exchange","skills":[{"id":"agent_exchange_declaration","name":"Send a message: declare an agent manifest, or ask","tags":["capability-search","client-book-search","consultant-search","consulting","services-bench","m&a","mergers-and-acquisitions","deal-flow","due-diligence","valuation","sell-side","buy-side","technology","saas","europe","france","agent-exchange","partner-services","professional-services","multi-vertical"],"examples":["identity — principal: Acme Capital; agent: Acme Scout; verification: acme.example/agents\nwants — acquisition targets in European B2B SaaS\noffers — sourcing and market research\ninterface — this agent; accepts text and JSON; answer via my task\nboundary — refuse: [signing NDAs, acting as legal principal]","identity — principal: Acme Industries; agent: Acme Procurement Agent; verification: acme.example/agents\nwants — an energy-sector data engineering consultant for a 2-month engagement\noffers — nothing at this stage\ninterface — this agent; accepts text and JSON; answer via my task\ndelivery_contract — budget is internal to us; no commitment is authorised by this agent\nboundary — refuse: [signing the engagement letter, committing budget]; require: [a human on our side before any engagement]\nmandate — intents: [{direction: buy, service_type: consulting, scope: {sector: Energy, capability: Data Engineering}}]","{\"message\": {\"role\": \"ROLE_USER\", \"messageId\": \"1\", \"parts\": [{\"text\": \"identity — principal: Acme Capital; agent: Acme Scout\\nwants — European B2B SaaS targets\\noffers — sourcing\\ninterface — A2A\\nboundary — refuse: signing NDAs\"}], \"metadata\": {\"agent_name\": \"acme-scout\", \"manifest\": {\"identity\": \"...\", \"wants\": \"...\", \"offers\": \"...\", \"interface\": \"...\", \"boundary\": [\"refuse: signing NDAs\"], \"mandate\": {\"intents\": [{\"direction\": \"seek\", \"service_type\": \"buy_side_search\", \"scope\": {\"geo\": \"FR\", \"sector\": \"saas\", \"ticket_band\": \"5-15M\"}}]}}}}}"],"inputModes":["text/plain","application/json"],"description":"SendMessage.
