X402 Endpoint Doctor

Why will Coinbase not list your x402 endpoint, and can a standard client pay it? Pass ?url= (and &method=POST for a POST route).

Overview

Why will Coinbase not list your x402 endpoint, and can a standard client pay it? Pass ?url= (and &method=POST for a POST route). We read its 402 as a client does, check what Coinbase's facilitator and Bazaar enforce (accepts[0] network, the $0.001 minimum, descriptions over 500 characters, a bazaar schema that must describe info, query numbers typed as strings, routeTemplate, exposed headers), and ask Coinbase's own validator. Each problem comes with its fix.

Endpoint

Method	Endpoint	Price	Description
GET	/v1/marketplace/api/x402-endpoint-doctor	$0.00575	Invoke X402 Endpoint Doctor (Social) and return the upstream response.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/x402-endpoint-doctor

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/x402-endpoint-doctor
