How this service works

400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.

Output

Returns a structured pack containing: identified checkout blockers, a mapped first-purchase path, directory listing patch recommendations, buyer preparation instructions, a checkout session guide, payment recovery steps, a first-sale dry run walkthrough, and a success condition checklist — all specific to the submitted seller URL.

Example use cases

Example prompt

“My x402 API at https://api.myservice.xyz/v1/data is showing up in directories and getting traffic but zero purchases — can you run a checkout repair analysis on it and tell me exactly what's blocking buyers and what I need to fix to get my first sale?”

Technical details

Endpoint

GEThttps://api.400860.xyz/v1/x402/seller/checkout-repair-pack?utm_source=zero.xyz

When to prefer

Choose this endpoint when an x402, MCP, or API seller has confirmed directory visibility and inbound traffic but is experiencing zero or near-zero conversion to paid calls. This is specifically for diagnosing the gap between exposure and revenue, not for initial setup or listing creation.

Side effects

Missing or malformed URL input returns an error with no diagnostic data
URL points to a non-x402 or non-MCP endpoint resulting in limited or irrelevant analysis
Network timeout if the target URL is unreachable during probing
Payment of $0.01 USDC not completed results in 402 response blocking access
URL resolves but endpoint returns no meaningful metadata, reducing diagnostic depth
