Real-time DeFi exploit feed via x402-paid API on Base (USDC), $0.10 per call.
What it does
The `/api/monitor/exploit-alert` endpoint is part of DeFi Shield, a suite of 69 paid API endpoints providing blockchain security intelligence to autonomous AI agents. This specific endpoint delivers a recent DeFi exploit feed — returning information about recent exploits, hacks, and security incidents in the DeFi ecosystem. It is priced at $0.10 per call, paid in USDC on Base via the x402 protocol.
DeFi Shield operates on a pay-per-request model where an agent sends a POST request with an x402 payment header, the facilitator verifies USDC payment on Base, the endpoint processes the request and returns JSON, and payment settles only on a successful response. The platform advertises free GET-based endpoint discovery on every route, a health endpoint at `/api/health` listing all endpoints and pricing, and an A2A discovery card at `/.well-known/agent-card.json`.
No detailed API documentation, request/response schemas, or examples were found for this specific endpoint — the `/docs` page returns 404. The probe confirmed the endpoint is live (HTTP 402 returned on POST), but the x402 challenge body was empty, so exact payment parameters (token address, network, facilitator address) could not be verified from the probe alone. The landing page states USDC on Base but this is not independently confirmed via the challenge payload.
Capabilities
Use cases
- —AI agents monitoring for recent DeFi exploits to protect portfolio positions
- —Automated risk systems checking for active exploits before executing trades
- —Security dashboards aggregating real-time DeFi incident data
- —Agent workflows that pause operations when new exploits are detected
- —Research tools tracking historical DeFi security incidents
Fit
Best for
- —Autonomous AI agents needing real-time DeFi exploit awareness
- —Trading bots that need to halt activity during active exploits
- —Security-focused DeFi portfolio management agents
Not for
- —Users needing free or subscription-based exploit data without per-call payment
- —Applications requiring non-crypto payment methods (endpoint requires USDC on Base)
Quick start
# Free discovery (GET)
curl https://defi-shield-hazel.vercel.app/api/monitor/exploit-alert
# Paid request (POST, requires x402 payment header)
curl -X POST https://defi-shield-hazel.vercel.app/api/monitor/exploit-alert \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-token>"Endpoint
Quality
The endpoint is confirmed live (402 on POST), and the landing page provides pricing and a general description. However, the x402 challenge body was empty, no OpenAPI schema exists, the docs page 404s, and no request/response examples are available. The endpoint's exact behavior and output format must be inferred from its name alone.
Warnings
- —x402 challenge body was empty — payment parameters (token address, facilitator, network) not independently verified from probe
- —No API documentation found (/docs returns 404)
- —No request or response schema available for this endpoint
- —Pricing ($0.10) is sourced only from the landing page, not from the x402 challenge payload
