Pay 1 USDC to receive 100 xTest tokens minted directly to your wallet via x402.
What it does
The xQuant Stonk endpoint is an x402-enabled API hosted on the xQuant quantitative trading platform. According to its listing, it accepts a payment of 1 USDC and in return mints 100 xTest tokens directly to the caller's wallet address. The endpoint is part of the broader xQuant platform, which describes itself as a quantitative trading platform with live APIs, EMA ribbon trading signals, and related documentation.
During probing, the endpoint returned HTTP 200 rather than the expected 402 payment-required challenge, which raises questions about whether the x402 payment flow is currently active or correctly configured. No OpenAPI schema, ai-plugin manifest, or agents.txt was found. The platform's documentation hub references an API reference, architecture docs, and developer guides, but the actual API base path (/api) returns a 404, and no detailed schema or parameter documentation was discovered in the crawl.
Because of the lack of a working 402 challenge, missing request/response schemas, and no concrete technical details beyond the high-level description, this listing should be treated as a stub with significant uncertainty about its current operational status.
Capabilities
Use cases
- —Purchasing xTest tokens programmatically via an x402 payment flow
- —Integrating token minting into an agent-driven crypto workflow
- —Testing x402 payment protocol integrations with a live endpoint
Fit
Best for
- —Developers experimenting with x402 payment protocol
- —Agents that need to acquire tokens via HTTP-native payments
- —Testing automated USDC-to-token swap flows
Not for
- —Production trading or investment decisions — xTest tokens appear to be test/experimental tokens
- —Users needing detailed API documentation or guaranteed uptime SLAs
- —Anyone expecting a standard 402 challenge flow — the endpoint currently returns 200
Quick start
# The endpoint is expected to use x402 protocol.
# A typical x402 flow would be:
curl -X GET https://x-quant-fund.vercel.app/api/xQuant-stonk
# If 402 is returned, pay the USDC amount specified in the challenge header,
# then re-request with the payment proof.Endpoint
Quality
The endpoint did not return a 402 challenge during probing (returned 200 instead), no OpenAPI schema or request/response examples exist, and the /api base path returns 404. The listing description is the only source of information. This is effectively a stub with unverified claims.
Warnings
- —Endpoint returned HTTP 200 instead of the expected 402 payment challenge — x402 flow may not be active
- —No OpenAPI schema, request/response examples, or parameter documentation found
- —The /api base path returns 404; only the specific /api/xQuant-stonk path was reachable
- —xTest tokens appear experimental/test — no information on token contract address or chain
- —Platform documentation references exist but actual API reference content was not crawled
