Bridge trust assessment and exploit history via x402-paid API on Base
What it does
The `/api/protocol/bridge-risk` endpoint is part of DeFi Shield, a suite of 69 paid API endpoints providing security intelligence for autonomous AI agents. This specific endpoint assesses cross-chain bridge trust and exploit history. It accepts POST requests and charges $0.50 per call in USDC via the x402 protocol on Base.
DeFi Shield covers 11 categories of DeFi security analysis including protocol intelligence, wallet profiling, MEV detection, NFT analysis, safety compliance, and real-time monitoring. The bridge-risk endpoint sits within the Protocol Intelligence category alongside endpoints for TVL decomposition, governance risk, oracle risk, and protocol comparison. All endpoints follow the same payment flow: the agent sends a POST 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 successful response.
Free discovery is available via GET on any endpoint path, and a health endpoint at `/api/health` lists all endpoints with pricing. An A2A discovery card is served at `/.well-known/agent-card.json`. No OpenAPI schema or detailed documentation page was found during crawling — the docs, pricing, and README paths all return 404. The exact request schema for bridge-risk is not documented in the crawled material, so the expected input fields (e.g., bridge name or protocol identifier) must be inferred or discovered via the free GET discovery on the endpoint.
Capabilities
Use cases
- —Autonomous agents evaluating bridge safety before executing cross-chain transfers
- —Portfolio managers assessing bridge risk exposure across multi-chain positions
- —Security researchers querying exploit history for specific bridge protocols
- —DeFi dashboards integrating bridge trust scores into risk displays
- —Automated trading bots checking bridge reliability before routing funds cross-chain
Fit
Best for
- —AI agents needing programmatic bridge risk data with pay-per-call pricing
- —Cross-chain DeFi operations requiring trust verification before bridging assets
- —Security-focused workflows that need bridge exploit history on demand
Not for
- —Users who need free or subscription-based bridge analytics without per-call payment
- —Applications requiring real-time bridge monitoring or streaming alerts (this is a one-shot query endpoint)
- —Non-crypto use cases unrelated to DeFi bridge security
Quick start
# Free discovery (no payment needed)
curl https://defi-shield-hazel.vercel.app/api/protocol/bridge-risk
# Paid request (requires x402 payment header)
curl -X POST https://defi-shield-hazel.vercel.app/api/protocol/bridge-risk \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-token>" \
-d '{"protocol": "multichain"}'Example

}Endpoint
Quality
The endpoint is live (402 challenge captured) and the landing page provides clear pricing ($0.50/call) and payment flow details. However, no OpenAPI schema, detailed docs, or example responses were found. The request body schema is inferred, not documented. The x402 challenge object was empty, providing no additional payment metadata.
Warnings
- —No OpenAPI or JSON schema available for request/response validation
- —Docs page returns 404 — no detailed endpoint documentation exists
- —The x402 challenge object was empty (no payment parameters captured), so exact payment details (token address, network, amount in base units) could not be independently verified
- —Request body fields (e.g., 'protocol') are inferred from context, not documented
