Pay 1 USDC on Base to receive 100 xTest tokens minted directly to your wallet.
What it does
The xQuant-stonk endpoint is an x402-enabled API on the Base network that mints 100 xTest tokens to the caller's wallet in exchange for a 1 USDC payment. The endpoint uses the x402 payment protocol: callers include an X-PAYMENT header with a valid payment proof, and upon verification the server triggers an on-chain token mint and returns a transaction receipt.
The response includes a transaction hash, the recipient address, a block explorer link, the payment amount, and a timestamp. The endpoint is part of the broader xQuant quantitative trading platform ecosystem, though this specific endpoint appears to be a demonstration or test token distribution mechanism rather than a production trading signal API.
Pricing is fixed at 1 USDC per call (maxAmountRequired: 1,000,000 in 6-decimal USDC units) paid to address 0x10875c46c5e7a45b062F8fEd17694799144D5008 on the Base L2 network. The payment asset is USDC at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. The endpoint supports a maximum payment timeout of 300 seconds.
Capabilities
Use cases
- —Acquiring xTest tokens programmatically via a single API call with USDC payment
- —Demonstrating x402 payment protocol integration for on-chain token minting
- —Agent-driven token acquisition on the Base network
Fit
Best for
- —Developers testing x402 payment protocol integrations
- —Agents that need to acquire xTest tokens on Base
- —Exploring pay-per-call crypto token distribution patterns
Not for
- —Production trading signal consumption (this endpoint mints test tokens, not trading data)
- —Users who need tokens on networks other than Base
- —High-frequency or bulk token minting (1 USDC per 100 tokens, fixed pricing)

}Endpoint
Quality
The endpoint is live with a valid 402 challenge and a well-defined output schema. However, documentation is thin—no dedicated page for this endpoint, no input schema beyond the POST method, and the xTest token itself is not documented. The response schema is inferred entirely from the outputSchema in the 402 challenge. The broader xQuant docs exist but don't specifically cover this endpoint.
Warnings
- —xTest tokens appear to be test/demo tokens; their utility or value is unclear
- —No input body schema documented—unclear if any request body fields are required or accepted
- —No dedicated endpoint documentation found; all details inferred from the x402 challenge
- —The example response is synthesized from the outputSchema, not from an actual observed response
