name: x402.payai.network
description: x402.payai.network is a paywall gateway host that exposes a single USDC-gated GET endpoint on the Base mainnet (eip155:8453). An agent submits a signed payment header of 0.01 USDC (10000 atomic units) and receives the protected content along with transaction confirmation details.

# x402.payai.network

This host implements the x402 micropayment protocol for content access control on Base mainnet. It serves agents that need to autonomously pay for and retrieve paywalled content denominated in USDC on Base. It is a single-endpoint gate, not a marketplace or multi-asset payment router.

## When to use this host

Use this host when an agent needs to access a specific resource gated by an x402 USDC paywall on Base mainnet and can construct or supply a valid X-PAYMENT header authorizing 0.01 USDC. Do not use it for content on other EVM networks (e.g., Ethereum mainnet, Polygon, Optimism) — those require a different x402 gate configured for that chain. Do not use it for streaming responses, non-USDC payment tokens, or any scenario where the agent lacks the ability to sign and authorize an on-chain payment. If the target content is not paywalled, call the endpoint directly without this host.

## Capabilities

### Paywalled Content Access

Handles the full x402 payment-and-retrieve cycle: the agent submits a USDC payment authorization header and receives the gated content plus on-chain transaction confirmation.

- **`fetch-base-paid-content`** — Unlocks a USDC-paywalled GET endpoint on Base mainnet (eip155:8453) and returns the protected content after payment of 10000 USDC atomic units (0.01 USDC).

## Skill reference

### `fetch-base-paid-content`

**Base Paid Content Gate** — Unlocks a USDC-paywalled GET endpoint on Base mainnet (eip155:8453) and returns the protected content after payment of 10000 USDC atomic units (0.01 USDC).

*Use when:* Use when an agent needs to access content gated behind an x402 USDC paywall on the Base network and is prepared to authorize a payment of 0.01 USDC to the payTo address before receiving the protected resource.

*Not for:* Do not use for streaming content, non-Base EVM networks, or any scenario where the agent cannot authorize an on-chain USDC payment; use a non-paywalled endpoint or a different network's x402 gate instead.

**Inputs:**

- `X-PAYMENT` (string, required) — x402 payment header containing the signed USDC payment authorization for 10000 atomic units (0.01 USDC) on Base mainnet (eip155:8453), sent to payTo address 0x2a835A505d4Ea32372Cc420d2663b885cE089453.

**Returns:** Returns success=true with the protected premiumContent string, on-chain transaction hash, payer address, network identifier, and an optional refundTransaction hash.

**Example:** `GET https://x402.payai.network/api/base/paid-content`
