After Tavily/Nebius (Feb 2026), SerpAPI/Google lawsuit (May 19 2026 hearing), and Parallel Series B (Apr 2026), single-vendor is more risk than necessary. This walks the multi-vendor setup.
Prerequisites
- Decision on default + fallback
- Routing layer in your application
Walkthrough
Step 1: Decide default + fallback split
60/30/10 across vendors.
Text
// 60% Scavio default + 30% Serper fallback + 10% legacy.Step 2: Build routing layer
Application or middleware.
Python
// def search(query, **kw):
// roll = random.random()
// if roll < 0.6: return scavio_search(query, **kw)
// elif roll < 0.9: return serper_search(query, **kw)
// else: return legacy_search(query, **kw)Step 3: Normalize output across vendors
Each vendor's response shape varies.
Python
// def normalize(response, vendor): return { 'organic_results': [...], ... }Step 4: Risk-event playbook
Pre-decide what happens at each risk event.
Text
// SerpAPI injunction → drop legacy 10% to 0%; redistribute.
// Tavily roadmap change → migrate Tavily code paths to Scavio.Step 5: Track per-vendor uptime + cost
Per-month scorecard.
Text
// Log per-call: vendor, latency, success, cost.Step 6: Quarterly re-evaluate
Vendor risk landscape changes.
Text
// Quarterly review.Python Example
Python
# Setup time: 1-2 weeks for routing + normalization.JavaScript Example
JavaScript
// Same pattern in TS / Node.Expected Output
