Pay for x402 resources — from your browser with your own wallet, or hands-free from your AI agent. Same protocol, same facilitator, six official ways in.
The Universal x402 Client is the easiest way to use x402 resources — no code, no keys pasted anywhere. Connect Pera or Lute and everything happens with wallet signatures.
Search, filter and browse merchants and resources with the exact same filter set as the x402 Intelligence dashboard — network, chain, currency, source, time range, country — plus the raw Bazaar catalog for brand-new listings.
The client shows you the live price from the resource's own 402 challenge, your wallet signs a single USDC transfer, and the facilitator settles it on-chain — network fees sponsored.
Responses render beautifully — JSON as a collapsible tree with copy and download, images inline, HTML sandboxed. Every MainNet purchase gets a Universal Receipt link.
Per-wallet history of everything you've done — purchases, verifies, settles — with your own totals up top: merchants used, resources bought, payments and volume.
Leave verified 5-star feedback (plus a message) on any purchase — itself a small paid x402 function (0.05 USDC on Algorand MainNet), so only real buyers can rate, and your rating rides permanently in the payment's on-chain note. This feedback directly affects merchant and resource ranking and reputation across x402 — your voice shapes who rises.
Run inside Claude Code:
/plugin marketplace add GoPlausible/claude-plugins /plugin install algorand-plugin@goplausible-claude-plugins
Ships the full Algorand MCP toolset plus x402 skills — your agent recognizes
an HTTP 402 on its own, checks the price, and completes the payment without you
lifting a finger. Optional — skip per-tool prompts by allowing the plugin's tools in
.claude/settings.json (or ~/.claude/settings.json):
{
"permissions": {
"allow": [
"mcp__plugin_algorand-plugin_algorand-mcp__*",
"Read(/skills/**)",
"Read(/references/**)"
]
}
}Run in your terminal:
codex plugin marketplace add https://github.com/GoPlausible/codex-plugins.git codex plugin add algorand@goplausible
Restart Codex (or start a new thread) and verify with /mcp — you
should see algorand-mcp. Optional — skip per-tool approval prompts in
~/.codex/config.toml:
[plugins."algorand@goplausible".mcp_servers."algorand-mcp"] enabled = true default_tools_approval_mode = "approve"
openclaw plugins install @goplausible/algorand-plugin openclaw gateway restart openclaw algorand-plugin setup openclaw gateway restart
Tools surface through mcporter — the same one-go payment call looks like this:
mcporter call algorand-mcp.make_http_request_with_x402 --args '{
"baseURL": "https://example.x402.goplausible.xyz",
"path": "/avm/weather",
"method": "GET",
"preferredNetwork": "testnet",
"maxAmountPerRequest": 10000
}'Prefer no local install at all? The plugins above bundle the local Algorand MCP (keys in an encrypted on-device wallet) — but any MCP-capable client can also connect straight to the hosted servers below, where no keys ever live on your machine.
No keys at all on your side. Sign in with Google, GitHub, X or LinkedIn; your Algorand account lives in a HashiCorp Vault and signs server-side. Full toolset including the knowledge base and DEX tools. Operates on Algorand MainNet only — real funds, real payments.
{
"mcpServers": {
"algorand-remote-mcp": {
"command": "npx",
"args": ["mcp-remote", "https://algorandmcp.goplausible.xyz/sse"]
}
}
}Same OAuth + Vault wallet as Remote, trimmed toolset, and MCP Apps UI widgets — payment confirmations, x402 requirements and Bazaar results render as interactive cards in clients that support them. Operates on Algorand MainNet only — real funds, real payments.
{
"mcpServers": {
"algorand-remote-mcp-lite": {
"command": "npx",
"args": ["mcp-remote", "https://algorandmcplite.goplausible.xyz/sse"]
}
}
}Both remote servers ship an algorand_mcp_skill tool — a built-in
operating manual covering every tool, the x402 payment flow and the safety rails. The optimum
way to start a session with either MCP is to ask your agent to read it first; the agent then
knows exactly how to discover, price and purchase without trial and error:
Read the Algorand MCP skill and follow it for this session.
All six surfaces — three plugins, three MCP servers — expose the same five
tools, discover resources from the same Bazaar, and settle through this facilitator
(https://facilitator.goplausible.xyz) by default:
| Tool | What it does |
|---|---|
make_http_request_with_x402 | The one-go call. Fetches the URL; on 402 it
reads the payment requirements, builds the atomic group (facilitator fee-payer first, your USDC transfer
second), signs, retries with PAYMENT-SIGNATURE, and returns the paid response — one tool call,
no manual steps. |
x402_discover_payment_requirements | Peek at a resource's price, asset and networks without paying — inspect-then-pay when you want explicit control. |
bazaar_list | Browse everything cataloged in the Bazaar. |
bazaar_search | Find resources by keyword, network or price. |
bazaar_get_resource_details | Full listing for one resource — description, schema, accepts, pricing. |
Built-in discipline, identical everywhere: always cap spend with
maxAmountPerRequest, default to preferredNetwork: "testnet", and confirm
before paying on MainNet. The two payment tools are name- and shape-compatible with Coinbase's
x402 MCP tools, so agents written against those work here unchanged.
Four ways to make a purchase — each prompt works verbatim in any of the plugins and MCPs above; copy the one that matches how you shop:
Search the x402 Bazaar for weather APIs on Algorand TestNet, pick the cheapest one and buy it — cap spend at 10000 microUSDC.
Fetch https://example.x402.goplausible.xyz/avm/weather and pay if required — cap it at 10000 microUSDC, TestNet.
Discover the payment requirements for https://example.x402.goplausible.xyz/avm/weather — show me the price and asset — then complete the purchase on TestNet.
Search the Bazaar for LLM inference APIs on Algorand MainNet under 0.2 USDC per call, show me the exact price, then buy one call — confirm with me before paying.
