Five findings. The first two are pure credit; Coinbase is genuinely ahead. Every finding reproducible with curl: exact command, exact status, exact observation. The ask is at the end, and it is small.
www.coinbase.com/llms.txt is a real, well-authored file that routes agents to Agentic Wallet, AgentKit, and x402. docs.cdp.coinbase.com ships a real llms.txt and a real A2A agent-card.json. This is the state of the art. The findings below are refinements at the edges: one stale file, one gap on the consumer host, and one genuinely new category, not a "you're behind" story.
No jargon. Two of the five findings are pure credit: Coinbase is genuinely ahead. These are the three that turn into money or momentum.
Automated review tools read that one file first, and its date lapsed roughly two years ago; a one-line refresh means the first thing a scanner checks about Coinbase passes clean.
The capability already exists on the docs host; mirroring it to the consumer front door means an assistant that lands there can transact, closing the last gap on the very standard Coinbase authored.
Every agent-payable merchant indexed so far sells digital data; funding one that settles verified real-world work extends Coinbase's own "agents that transact" story from screens to the ground, and it already runs on Base.
www.coinbase.com/llms.txttext/plain; charset=utf-8 · 5,098 B · server: cloudflareMost consumer domains 404 here. Coinbase ships a genuine agent index that disambiguates "agent + wallet" paths (Agentic Wallet vs Embedded vs Server Wallets vs AgentKit) and points to docs.cdp.coinbase.com/llms-full.txt for deep retrieval. Credited without reservation.
Why it matters: it makes the two findings below easy wins: you have already internalized the pattern; the gaps are extending it one host over and adding one merchant category.
docs.cdp.coinbase.com/.well-known/agent-card.jsonapplication/json · protocolVersion 0.3 · server: VercelThis is exactly the artifact Robinhood's consumer host only pretends to serve (there, agent-card.json returns an HTML shell). Coinbase's docs return real JSON with a named skill and transport binding. Credited.
Why it matters: it proves the capability lives in-house. Finding 4 is simply: it isn't on the consumer host too.
www.coinbase.com/.well-known/security.txttext/plain · 117 B · Expires: 2024-06-01T00:00:00zThe file points to a managed HackerOne program (good), but its Expires lapsed roughly two years before capture, and it carries no Encryption or Canonical field. RFC 9116 treats a past Expires as "should not be used." For the company defining agentic-payment norms, a stale machine-readable security signal is a precise, easily-fixed miss.
Why it matters: automated diligence agents read this exact file. An expired date is the one thing a scanner flags before it reads anything else you ship.
www.coinbase.com/.well-known/x402 · /.well-known/agent-card.json · /.well-known/ai-plugin.jsonThe A2A agent card (Finding 2) lives only on docs; the consumer domain that does ship llms.txt has no agent card and no /.well-known/x402 discovery manifest. So an agent that lands on coinbase.com can read the prose index but cannot discover a callable agent endpoint or an x402 payable surface there, from the very company that authored the x402 discovery pattern.
Why it matters: this is a one-file extension of what you already ship on docs. Mirroring the docs agent card to www.coinbase.com and adding a consumer /.well-known/x402 closes the gap and models the standard on your highest-traffic host.
x402 and Agent.market/the Bazaar have proven agents will pay for digital services: API calls, data, compute. The category that closes the loop between the onchain economy and the physical one is a proof-of-outcome merchant: an agent pays, and what settles is a verified real-world result with an immutable receipt. That merchant type does not exist in the directory yet.
EcoWealth is that merchant, live today, on your rails: standard accepts[] emitted, EIP-3009 exact-scheme accepted, self-settled with no facilitator. Discoverable at vealth.net/.well-known/x402 (22 endpoints); settlement on the EWP contract 0x76c17C…A14B on Base mainnet (workId 14 settled); board 7,624 postings / ~$671k posted (vealth.net/labor/stats). Pay $0.10 → get a bounded ecological work packet → its completion writes a tCO2e retirement receipt.
Why it matters to Coinbase: your agentic-commerce thesis needs merchants to be real for the flywheel to spin. A proof-of-outcome category extends the story from "agents buy data" to "agents fund verified physical work", and the first such merchant is already standard-conformant and running on Base.
Proof first, then one small step tied to your own agentic-commerce thesis. The deliverable is an on-chain receipt settled over your own standard.
