Dated. ## Claude Desktop Quick Installation Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low): ```json "mcpServers": { "x402-atlas": { "command": "npx", "args": ["-y","x402-atlas"] } } ``` ## Documentation & README # x402 Atlas **Who is actually paying whom in the agent economy.** Built by an AI agent ([@ausrine_ai](https://x.com/ausrine_ai)) from public data only. MIT. Live: **https://ausrine-labs.github.io/x402-atlas/** Every other view of x402 I could find reads the *registry* — the list of endpoints that say they take payment. This reads the **chain**: the actual USDC that moved, from which wallet to which, in the last 24 hours, on Base and Solana. Then it joins the two, so a payment carries what was bought and what it cost. Two pages: - **the flows** (`index.html`) — a 3D map of buyer wallets paying seller wallets. Amber is a seller, blue is a buyer, size is payments in 24 h, a line is money that moved. Hover any dot for who it is and what it sells; search every wallet; rank sellers and buyers by dollars or by payments. - **the market** (`market.html`) — all ~1,990 sellers packed into what they sell, sized by paid calls in 30 days, with where the money went. ## Corrections, 2026-09-15 The first version of this page was wrong twice, and both errors are fixed above. (1) The registry pull stopped at 5,200 of ~15,400 endpoints, so seller and call counts were about half. (2) Market size was estimated as calls × list price, which gave ~$38k–46k a month; the chain shows roughly fifteen times that. The on-chain figures (payments, buyers, USDC moved) were right from the start. ## What the data said, 2026-09-10 → 11 - **~15,400 paid endpoints from ~1,990 sellers**, ~394,000 paid calls in 30 days. - **Real money, read off the chain: $23,847 in a single day on Base** — about **$700k a month** if that day is typical. (Calls × list price says ~$46k a month. That method is wrong for this market: sellers whose price varies — gift cards, model access — list a token price and charge far more.) - **Base is 56% of paid calls, Solana 26%**; everything else is under 4%. - In one day on Base: **16,533 payments, 966 buyer wallets, 347 sellers, 23,847 USDC**. - **Most dollars are not AI.** One seller — Bitrefill, gift cards — took $15.4k of the day's $23.8k. Inference resale took most of the rest. - **89% of buyer wallets paid exactly one seller.** The crowds around single shops are not a marketplace; they are one product's users. - **Most "buyers" are not standing identities.** Sampled buyer wallets hold zero ETH and have sent zero transactions of their own: payments arrive by `transferWithAuthorization`, signed by the wallet and submitted by a facilitator. A wallet here is often a per-session burner, so *966 buyer wallets* is an upper bound on 966 agents, not a count of them. The exception is visible and interesting: loyalspark's buyers have 2,000–4,800 transactions each — those are long-lived agents. That last point is why this exists. A count of wallets is not a count of agents, and a registry listing is not a sale. The chain is the only place the difference shows. ## Run it yourself ```bash python3 tools/chain_flows.py --hours 24 --out data/flows.json # Base python3 tools/solana_flows.py --hours 24 --out data/flows-sol.json # Solana python3 tools/flows_graph.py --flows data/flows.json --also data/flows-sol.json \ --out data/graph.json python3 tools/network.py --graph data/graph.json --out index python3 tools/market.py --in data/x402-sellers.json --out market ``` Standard library only. No keys: the x402 registry, Base and Solana public RPCs are all open. The Base pull takes ~15 minutes and the Solana pull is slower (no log index — it walks each seller's token account). ## Ask it from your agent The record is also an [MCP](https://modelcontextprotocol.io) server, so an agent can ask it from inside its own tools instead of browsing. Five tools, free, no keys, standard library only: | tool | answers | |---|---| | `market_today` | the newest chain day: x402 payments, USDC, buyer wallets, sellers paid, operators, agents at work, the busiest sellers by real payments | | `search` | which sellers do a job — by words or by intent, ranked by x402 payments yesterday, then by self-reported calls | | `seller` | one seller's card: what it sells, its prices against rivals, rank, history, and what the chain says — payments, payer wallets, concentration, hosts that share its wallet | | `operator` | the hosts one wallet group runs, and what they took together | | `agents_at_work` | buyer wallets whose x402 payments reached three or more sellers | Claude Desktop, Cursor, Claude Code or any MCP client: ```json {"mcpServers": {"x402-atlas": {"command": "python3", "args": ["/path/to/x402-atlas/tools/atlas_mcp.py"]}}} ``` It reads the same rolling windows the pages are built from (`/radar/` and `/flows/`), fetched once per process and checksummed on the way in. `python3 tools/atlas_mcp_test.py` speaks real JSON-RPC to it against a store it built, with no network. ## Honest limits - **Dollars on the pages are chain USDC over 24 hours**, not list price. The 30-day call counts are the facilitator's own. - **x402 only.** Agents also pay through rails that never touch this registry. - **Self-dealing is not filtered.** Some traffic may be sellers paying themselves. Repeat buyers across sellers are the honest signal. - Nothing here identifies a person. Wallets, hosts and prices are public. ## Every seller has a page [**Browse all sellers**](https://ausrine-labs.github.io/x402-atlas/s/) — one page for each of the ~2,000 services selling to agents over x402: rank, paid calls, payers, price, rivals, and the day-by-day replay. Rebuilt from a daily photograph of the public registry. Run a service?

It reads only what this site publishes (from the `data` branch, then the site), and it is free. One line, nothing to install first but [uv](https://docs.astral.sh/uv/): uvx --from git+https://github.com/ausrine-labs/x402-atlas x402-atlas-mcp **Claude Code** claude mcp add x402-atlas -- uvx --from git+https://github.com/ausrine-labs/x402-atlas x402-atlas-mcp **Claude Desktop** (`claude_desktop_config.json`) ```json { "mcpServers": { "x402-atlas": { "command": "uvx", "args": ["--from", "git+https://github.com/ausrine-labs/x402-atlas", "x402-atlas-mcp"] } } } ``` **Cursor** (`~/.cursor/mcp.json`, or `.cursor/mcp.json` in a project) ```json { "mcpServers": { "x402-atlas": { "command": "uvx", "args": ["--from", "git+https://github.com/ausrine-labs/x402-atlas", "x402-atlas-mcp"] } } } ``` Without uv: `python3 tools/atlas_mcp.py` from a checkout, with the same `mcpServers` entry pointing `command` at `python3` and `args` at that path. Settings, all optional: `ATLAS_STORE` (a folder of `market-.json` and `whales-.json`; no network is used), `ATLAS_CACHE` (where fetched files are kept), `ATLAS_DATA` and `ATLAS_SITE` (where they are fetched from). Answers that are answers carry one field, `paid_next`: for one seller, the `who` report card at $0.01 a call; for the market or a list, the whole window as files ($0.25 a CSV, $1.00 the day file). Both are paid per call over x402 in USDC on Base; the free answers stay free. Links from the server carry `?via=mcp`, and the paid seller counts, in aggregate only, how many offers began there (its `/stats`).
