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 the GitHub account minia2a for this listing. That does not show the account is the product's maker.

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

Lets an assistant browse and call pay-per-call x402 APIs on the minia2a.uk marketplace, paying per request in USDC.

What you can do: Exposes eight tools for the minia2a.uk x402 marketplace: list and search services, get a service's price, endpoint and schema, read platform statistics, register an agent, check credits, claim credits from a USDC transfer, call a service, and validate an x402 endpoint. Calls go through the HTTP 402 payment flow, with credits decrementing per call or a free trial used anonymously.
When to use it: Useful when an assistant needs to discover and consume third-party paid APIs without subscriptions or API keys, and when per-call USDC micropayments are acceptable. Also useful for checking whether an x402 endpoint is reachable and payment-ready.
Requirements: Runs locally over stdio via npx from the npm package minia2a-mcp, so Node.js and network access are needed. No environment variables or headers are declared. Registration uses a self-custody wallet and an EIP-191 signature; a wallet can be generated if none is supplied.

Before you install

Calls spend real money: services are paid per call in USDC, and buying credits means submitting an on-chain USDC transfer hash. Registration may generate a wallet and return its private key, so handle that key carefully. The server can register an agent and call external paid endpoints, and budget controls such as .agent-budget are described as optional safeguards.

Installation

In SourceWeft

Open Minia2a Mcp in the dashboard and add it to a workspace.

`minia2a_check_endpoint` ← NEW in v1.1.3

Validate any x402 endpoint for Claude Code auto-mode readiness (Aug 14, 2026).

Claude Code auto mode becomes the default on August 14. Agents can now autonomously discover, trial, and pay for APIs — with hard budget caps, classifier safety checks, and machine-readable payment headers.

minia2a is auto-mode ready:

/api/agent-ready — machine-readable handshake with payment info, registration endpoint, and quickstart
402 body: accepts[] array (amount/asset/network/payTo/scheme) — agent parses full payment instruction (x402 V2)
.agent-budget v1.1 — 7-field autonomous-purchasing controls (per-call / per-task / confirmation / dedupe / settlement / audit)
15 free trial calls shared globally — no wallet, no registration
500 free credits on registration — try any paid endpoint

What is x402?

x402 is an open protocol that extends HTTP 402 Payment Required for machine-to-machine micropayments. Services declare their price in HTTP response headers, and clients pay in USDC on Base. No intermediaries, no settlement delays. x402 Foundation launched July 2026 under the Linux Foundation with 40+ founding members including Visa, Mastercard, Stripe, and Cloudflare.
