CoinGecko x402 endpoints now payable in USDC on Polygon

CoinGecko's x402 pay-per-use data endpoints now accept USDC payments on Polygon, per Polygon's official account. AI agents can pay per request for market data — token prices, DEX liquidity, and trending activity — without moving funds off Polygon, and CoinGecko has cut x402 pricing 50% to $0.005 per call, billed as "half the cost, twice the data" for agent budgets.

• x402 uses the HTTP 402 Payment Required flow: the server returns payment requirements, the wallet signs a USDC authorization, and the agent retries the request.
• USDC payments it adds to the chains where agent funds already sit, removing the need to bridge before paying for data.
• The integration extends Polygon's AI-agent payments push, adding data access to the wallet-level spend rails Polygon has been rolling out.
