Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Finds paid x402 APIs for a task — sellers, prices, networks and evidence — and reports agent-economy market data across protocols.

What you can do: Search verified x402 sellers by capability, with price, networks and evidence of a live 402 or manifest
Read market statistics: seller counts by source, median declared price, and 30-day x402 totals
List the paid data products hosted on this server, such as wallet, sanctions, LEI, SEC and domain checks
Pick the best paid service for a plain-language task, with up to four alternatives
Query agent-economy data per protocol (x402, Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004) and search callable services across protocols
When to use it: Useful when an agent needs to find or compare paid x402 services for a task, or wants market-level data on the agent economy before choosing a provider. Most tools return a paid request rather than the data itself, so it suits agents set up to pay per call.
Requirements: Remote streamable HTTP endpoint; no account, API key or environment variables are declared. Paid tools require an x402 or MPP client to pay per call, or a prepaid access key bought from the server's key page. Network access to the endpoint is required.

Before you install

Most tools return a paid request and charge per call (for example $0.01 for the routing tool, $0.002–$0.003 for economy tools), so an agent with payment capability can spend money. A free trial exists but is limited per tool, per client and per network address per day. Statistics cover only the verified seller set, not the whole market.

Installation

In SourceWeft

Open P0: x402 service search in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank%2Fx402-service-search/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

search_x402_services

Search x402 services

Search verified x402 sellers by capability (from Agenstry, Open 402, pay.sh, the Official MCP Registry, apis.io and other public registries; each with price, networks and evidence of a live 402 or manifest). Free tier returns the top 5; full results are the paid /search endpoint (x402 or MPP) on this host. Calls and paying wallets are P0's own on-chain transfer counts, null where not measured. Not for picking one service for a concrete task (use best_service_for_task), for market-wide totals (use x402_market_stats) or for this host's own products (use list_paid_data_products).

Parametersqueryrequirednetworkinclude_testnets

x402_market_stats

x402 market stats

Statistics of the verified x402 seller set (sellers by source and evidence, median declared price; not the whole market) and 30-day x402 market totals from x402stats (CC BY 4.0, attributed in the answer). No parameters. Market-wide totals only, no per-service rows; for individual services use search_x402_services; for this host's own tools use list_paid_data_products.

Takes no parameters.

list_paid_data_products

List paid data products

List the paid data products on this host (wallet balances and EVM chain reads, payment check, sanctions, payee and counterparty checks, risk labels, LEI and bank lookups, SEC filings and contract awards, vulnerability, package and IP checks, domain and site checks, email and URL checks, interest rates, news, weather and hazards, Wikipedia knowledge search, the agent-economy index across protocols, time, random and utilities, agent memory, batch variants and the /buy/* service orders): route, price per call in USD, parameters and an example request URL. The data itself is paid per call over x402 or MPP at that URL. Lists THIS host's own paid tools only; to find third-party APIs use search_x402_services.

Parametersroute

best_service_for_task

Best service for task

Use when a router agent must pick which paid x402 service to send a task to: send the task in plain words, get the top listing from P0's snapshot of listed x402 services plus up to 4 alternatives. Returns the paid x402 request for your input (GET /route, $0.01 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Paid pick of one service for one task; for free browsing and comparing use search_x402_services. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Parameterstaskrequired

economy

Economy

Use when you need the agent economy beyond x402 in one call: per protocol. Returns the paid x402 request for your input (GET /economy, $0.003 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Takes no parameters.

economy_protocols

Economy protocols

Use when you need one agent-economy protocol in detail: every normalised row (per chain or rail, all-time and 30-day windows) for x402, Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004. Returns the paid x402 request for your input (GET /economy/protocols, $0.002 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price.
