Gemini Enterprise (formerly Agentspace) acts as an A2A orchestrator and host platform — it registers, discovers, and routes tasks to external A2A-compliant agents; external vendors publish A2A-compliant agents that can be added to and invoked from the Gemini Enterprise agent ecosystem.

Google Cloud's Gemini Enterprise platform is one of the primary originators and adopters of the A2A protocol. Official Google Cloud documentation covers registering, managing, and invoking A2A agents, and partner agents from companies such as Box, Workday, Salesforce, and ServiceNow are integrated via A2A. See https://docs.cloud.google.com/gemini/enterprise/docs/register-and-manage-an-a2a-agent for the canonical integration docs.

No evidence found that gemini.com (the cryptocurrency exchange) participates in the Agentic Commerce Protocol. Named ACP launch partners and integrators include Target, Sephora, Nordstrom, Lowe's, Best Buy, The Home Depot, Wayfair, Etsy, Shopify merchants (Glossier, Vuori, Spanx, SKIMS), PayPal, and Worldpay — all retail or payment entities, not crypto exchanges. ACP is gated behind an approved-partner application process, and gemini.com's crypto-exchange business model does not align with the retail/checkout merchant category ACP is designed for.

gemini.com is the Winklevoss-founded cryptocurrency exchange, not to be confused with Google's Gemini AI. Searches against the full list of ~60 organizations that co-announced and endorsed AP2 at the FIDO Alliance donation (including Adyen, American Express, Coinbase, Etsy, Mastercard, PayPal, Revolut, Worldpay, and others) returned no mention of gemini.com. No vendor-specific AP2 documentation, partnership announcement, or integration was found for the Gemini crypto exchange.

Crypto exchange trading agent interface: enables AI agents to place orders, access real-time market data, manage account positions, and execute trading strategies on the Gemini (gemini.com) crypto exchange. Documented as a locally-run MCP server (Node.js package) connecting via stdio transport, not a hosted remote endpoint.

Gemini (gemini.com) officially announced MCP as their fourth protocol alongside REST, WebSocket, and FIX, confirmed in their shareholder letter and developer platform at https://developer.gemini.com/agentic/agentic. The MCP server is open source, runs locally (stdio), and requires exchange API credentials obtained from Settings → API on exchange.gemini.com. No remote/hosted MCP endpoint found; the interface is locally-deployed by the caller.

No evidence that gemini.com (the Gemini cryptocurrency exchange) appears in any MPP launch partner list or registry of MPP-enabled services. Named MPP ecosystem partners include Anthropic, OpenAI, DoorDash, Mastercard, Nubank, Ramp, Revolut, Shopify, Standard Chartered, Visa, and Cloudflare — Gemini is absent from all sources checked. The mpp.dev/services directory was inspected and contains no reference to Gemini.

gemini.com is the Gemini cryptocurrency exchange; no evidence of NLWeb /ask or /mcp endpoint adoption was found for this domain. Named NLWeb launch partners and discussants in publicly available sources include Microsoft-aligned Azure/Cloudflare integrations, none of which reference Gemini. A targeted search returned no results connecting gemini.com to any NLWeb implementation.

Consumer/agent surface: gemini.com (the Gemini app) is an explicitly named UCP buyer-side surface through which shoppers initiate purchases; merchants expose three REST endpoints (session create, update, complete) that Gemini invokes to complete checkout. Gemini does not host merchant-side endpoints — it is the initiating agent, not the integration target. Merchant onboarding requires joining a waitlist and working with Google directly.

UCP is an open standard co-developed by Google with Shopify, Etsy, Wayfair, Target, and Walmart; gemini.com is explicitly listed as a consumer surface alongside AI Mode in Google Search. Merchant integration documentation is at https://developers.google.com/merchant/ucp. Access is gated behind a waitlist — merchants must contact Google before receiving credentials, placing this firmly in partner_only rather than open.

WebMCP is a browser-layer protocol co-developed by Google and Microsoft (W3C Community Group draft) where websites expose agent-callable tools via the navigator.modelContext API to an in-browser agent. The agent-side consumer of WebMCP is "Gemini in Chrome" (a browser-integrated assistant feature), which is architecturally distinct from gemini.com as a website. No evidence was found that gemini.com itself implements WebMCP tool exposure on its own pages; as an AI chat interface, it functions on the agent/consumer side of this protocol rather than the publisher/tool-exposure side. Named I/O 2026 launch partners were referenced in search results but not enumerated.

No evidence of gemini.com involvement in x402 was found. The x402 Foundation's published ecosystem and partner lists name Adyen, Fiserv, Google, Mastercard, Shopify, Cloudflare, Quant Network, and Solana as members — gemini.com does not appear. Searches across both x402.org and Coinbase's own x402 launch materials returned no results mentioning Gemini.

Gemini (gemini.com), the cryptocurrency exchange, launched an Agentic Trading feature that explicitly supports connecting ChatGPT (and Claude) to user accounts, but this is implemented via the Model Context Protocol (MCP), an open standard — not a build specifically for OpenAI's ChatGPT Apps platform. No evidence was found of a dedicated OpenAI Apps SDK integration or a ChatGPT-platform-specific app built by Gemini. The ChatGPT support found is purely MCP-mediated, not a vendor-specific Apps SDK surface.

Trading and market-data REST API covering order management (place, cancel, query), market data (order books, tickers, trade history), derivatives (perpetual contracts), fund management, account administration, and instant-quote execution at api.gemini.com

Gemini Trust Company (gemini.com) publishes a fully documented proprietary REST API at developer.gemini.com and docs.gemini.com. Public endpoints (market data) require no authentication; private endpoints use a self-serve API-key/HMAC scheme. API keys can be created by any registered Gemini account holder without a sales relationship.

Real-time WebSocket API for order events and market data streaming, including a next-generation 'Fast API' unified connection with sub-10ms latency for order placement and market data in a single session

Gemini's WebSocket API is fully documented at developer.gemini.com/websocket and is distinct from the REST API in both transport and capability. A newer 'Fast API' unified connection is recommended for new integrations, while legacy Order Events and Market Data WebSocket endpoints remain supported.

Documentation index for AI/LLM consumers covering the full Gemini crypto exchange developer API surface, intended to be fetched as an entry point for agent-driven API discovery.

Gemini (the crypto exchange, gemini.com) publishes an llms.txt file at https://developer.gemini.com/llms.txt, explicitly advertised on their developer portal homepage with the prompt "AI/LLM users: Fetch the complete documentation index at developer.gemini.com/llms.txt". The changelog entry also notes a fix to llms.txt generation, confirming active maintenance of the file. No AGENTS.md or /.well-known/agent file was found; /.well-known/security.txt is present but is a standard security contact file, not an agent-discovery declaration.
