Copy trading signals derived from on-chain wallet activity, paid per call via x402 on Base.
What it does
The `/api/wallet/copytrading` endpoint is part of DeFi Shield, a suite of 69 paid API endpoints providing security intelligence and DeFi analytics to autonomous AI agents. This specific endpoint generates copy trading signals by analyzing wallet activity on-chain. It is one of six Wallet Intelligence endpoints offered by the platform.
Payment is handled via the x402 protocol using USDC on Base. The listed price is $0.75 per call. Agents send a POST request with an x402 payment header, the facilitator verifies USDC payment on Base, and the endpoint returns JSON results upon successful payment settlement. Every endpoint also supports a free GET request for discovery purposes, returning metadata and an `llm_usage_prompt` to help agents understand the endpoint's capabilities.
DeFi Shield provides agent discovery via `/.well-known/agent-card.json`, a health endpoint at `/api/health` listing all endpoints and pricing, and analytics at `/api/analytics`. No OpenAPI schema or detailed documentation page was found during crawling (the `/docs` path returns 404), so the exact request/response schema for this endpoint is not documented in the available material. The probe confirmed the endpoint is live, returning a 402 status on POST as expected for x402 endpoints, though the challenge object was empty, which may indicate a minimal x402 implementation.

Quick start
# Free discovery (GET returns endpoint metadata)
curl https://defi-shield-hazel.vercel.app/api/wallet/copytrading
# Paid request (requires x402 payment header)
curl -X POST https://defi-shield-hazel.vercel.app/api/wallet/copytrading \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-token>" \
-d '{"address": "0x..."}'Example
Request
{
"address": "0x1234567890abcdef1234567890abcdef12345678"
}Endpoint
Quality
The endpoint is confirmed live (402 on POST), and the landing page provides pricing and a general description. However, the x402 challenge object was empty, no OpenAPI schema exists, no detailed docs are available, and the exact request/response format is inferred from sibling endpoints rather than documented. The example request is extrapolated from the quick-start pattern shown on the homepage.
Warnings
- —No OpenAPI or JSON schema available for request/response validation
- —The x402 challenge object returned empty — payment parameters not fully verifiable from probe
- —Documentation page (/docs) returns 404; no detailed endpoint docs found
- —Request and response schemas are inferred, not confirmed
