Compares multiple API endpoint URLs side-by-side by availability, latency, trust score, response validity, and schema consistency, returning a ranked recommendation.

StatusUnknown
Output
Returns a timestamped comparison array where each URL entry includes its rank, trust score (0–100), availability boolean, latency in milliseconds, response validity flag, schema consistency flag, and a list of issues found. Also returns the single best-ranked service URL and total count of endpoints compared.
Example use cases
Example prompt
“Compare these three API endpoints for me and tell me which one is the most trustworthy and available: https://api.example.com/v1/prices, https://api.example.com/v2/data, and https://api.example.com/v3/quotes — rank them by trust score and latency.”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/trust/service-compareWhen to prefer
Use this endpoint when you need to objectively choose between multiple competing API data sources and want a trust-and-availability ranking rather than manual spot-checking. Ideal when an agent must select the best live endpoint from a pool of candidates (e.g., price feeds, quote APIs, DeFi data providers) and needs a structured recommendation with latency and schema-consistency signals.
Side effects
- All endpoints unreachable — returns comparison array with available:false and trustScore:10 for all entries, bestService still set to rank-1 URL
- Invalid or malformed URL in input array — may cause parsing errors or zero-latency unreachable result
- Empty urls array — likely returns empty comparison with totalCompared:0
- Downstream API probe timeout — latency recorded but availability marked false
- x402 payment failure — endpoint returns 402 if USDC payment not attached
