## MCP tools (6)

### `minia2a_list_services` (~142 tokens)

List available x402 services on minia2a.uk — the micropayment marketplace for AI agents. Returns service name, description, price, and endpoint for each service. Use this to discover what capabilities are available before calling them.

Input parameters:

- `category` (string): Filter by category (e.g., 'crypto', 'utility', 'data', 'ai')
- `limit` (number): Max number of results to return (default 20)
- `search` (string): Search term to filter services by id, name, or description. Hyphens and underscores are treated as spaces, so 'crypto-price' and 'crypto_price' both match.

### `minia2a_get_service` (~71 tokens)

Get detailed information about a specific x402 service on minia2a.uk, including its price, endpoint URL, input schema, and usage instructions. Use this before calling a service to understand what it needs.

Input parameters:

- `serviceId` (string, required): The service ID or name to get details for

### `minia2a_get_stats` (~47 tokens)

Get current platform statistics for minia2a.uk — total services, registered agents, transaction volume, uptime, and more. Useful for understanding the marketplace's scale and health.

### `minia2a_register` (~198 tokens)

Register a self-custody wallet on minia2a.uk to publish your own services (EIP-191 signature). Registration is for publishing — it is NOT required for trials: any wallet signed in minia2a_call_service already gets 5 free trial calls. If you don't provide a wallet+signature, this tool generates a fresh wallet, signs 'minia2a register: <your-wallet>' with EIP-191, registers it, and returns the private key — store it, the platform never holds it.

Input parameters:

- `name` (string, required): A name for your agent (e.g., 'my-trading-bot')
- `signature` (string): EIP-191 signature of 'minia2a register: <wallet>'. Required if you supply a wallet.
- `wallet` (string): Your existing self-custody wallet address (0x...). Omit to have a fresh wallet generated for you.

### `minia2a_call_service` (~447 tokens)

Call an x402 service on minia2a.uk. Three access paths: (1) omit everything for the paid 402 path (sign a wallet for 5 free trial calls — no registration); (2) pass privateKey (or set MINIA2A_PRIVATE_KEY) for your wallet's own 5 trials — the key never leaves this process, it only signs the per-call trial message; (3) when both are exhausted the endpoint returns HTTP 402 with a machine-readable accepts[] array — pay in USDC and retry with a PAYMENT-SIGNATURE header (x402 V2). Set autoPay:true together with privateKey to have a 402 paid automatically in USDC on Base and the call retried — the wallet must hold USDC or the call still returns payment_required (never charges silently). Note that wallet= on its own does NOT reach the wallet bucket; the signature is what does. Service parameters go INSIDE `params`; a top-level key that is not one of the five declared names is rejected by name rather than dropped.

Input parameters:

- `autoPay` (boolean): When true and a privateKey is available, a 402 Payment Required response is paid automatically in USDC on Base via x402 and the call retried. Default false — you get a payment_required response inste…
- `params` (object): JSON parameters to send to the service. These are the service's OWN parameter names (e.g. {"ext":"json"} for x402-mime-type), nested here — not flattened onto the top level.
- `privateKey` (string): Private key of your wallet, used locally to sign the trial message (EIP-191). Never transmitted — only the resulting signature is sent. Falls back to the MINIA2A_PRIVATE_KEY env var.
- `serviceId` (string, required): The service ID (e.g., 'x402-gas') or full endpoint path
- `wallet` (string): Your self-custody wallet address (0x...). Without privateKey this alone does not draw on the wallet's trial bucket.

### `minia2a_check_endpoint` (~139 tokens)

Validate any x402 endpoint for autonomous-agent (Claude Code auto-mode) readiness. Checks 9 signals: HTTP reachability, JSON content-type, payment challenge (canonical PAYMENT-REQUIRED header or legacy x-402-* headers), payment amount, network, recipient, trial info, registration path, and /api/agent-ready handshake. Returns a score (0-100%) with per-check PASS/FAIL detail. Use this before calling a paid endpoint to verify it works with autonomous agents.

Input parameters:

- `endpointUrl` (string, required): The endpoint URL to validate (e.g., 'https://minia2a.uk/x402/gas')
