description: QRBase (www.qrbase.xyz) exposes a single diagnostic endpoint that verifies x402 payment-gated API access on the Base blockchain using USDC micropayments. It returns confirmation metadata including the sender address, transaction hash, and gated content payload. No production data or QR code generation is available through this skill.

# www.qrbase.xyz

QRBase is a service oriented around QR code generation and x402 payment-gated APIs on Base. The single skill currently exposed is a diagnostic ping endpoint intended for developers and agents to confirm that x402 USDC micropayment infrastructure is functioning correctly. It is not a general-purpose data or QR code API at this time.

## When to use this host

Use this host only when an agent needs to verify that x402 USDC micropayment infrastructure is working on Base — for example, during integration testing or debugging of payment-gated API flows. It returns a transaction hash and sender address useful for confirming a payment was accepted. Do not use it for QR code generation, production data retrieval, or any functional API output; it is a diagnostic endpoint only. For actual QR code generation or other Base payment-gated data services, look for hosts with production-grade skills.

## Capabilities

### x402 Payment Access Verification

Confirms that x402 payment-gated API access is operational on Base by sending a paid GET request and returning transaction metadata and gated content confirmation.

- **`verify-x402-api-access`** — Sends a paid GET request to the QRBase ping endpoint and returns confirmation of x402 payment access including sender address, transaction hash, and gated content.

## Skill reference

### `verify-x402-api-access`

**QRBase x402 Ping** — Sends a paid GET request to the QRBase ping endpoint and returns confirmation of x402 payment access including sender address, transaction hash, and gated content.

*Use when:* Use when an agent needs to verify that x402 payment-gated API access is working correctly on Base, or to confirm a USDC micropayment was accepted and retrieve the associated transaction hash and premium content.

*Not for:* Do not use for production data retrieval or QR code generation; this is a diagnostic ping endpoint only.

**Returns:** Returns x402Version, success=true, a payment confirmation message, the on-chain transaction hash, the sender address, and a data object with premium=true and a gated content string.

**Example:** `GET https://www.qrbase.xyz/api/x402/ping`
