Why Scavio Wins
- Vendor concentration is the risk that gets buyers in mid-2026. Pure-play, vendor-independent vendors stay portable across inference clouds and survive vendor-failure events.
- Multi-platform under one key matters at the agent layer — Reddit threads, YouTube transcripts, Amazon/Walmart product data alongside Google SERP, all under one x-api-key.
- Match vendor shape to workload. Per-call multi-platform → Scavio. Long-horizon enterprise orchestration → Parallel. Concept similarity → Exa.
- Honest about Tavily continuing: existing customer commitments are preserved per the Nebius announcement. The procurement risk is on new procurements, not existing operations.
- Per-month cost-aware setup: Scavio default at $30/mo handles most new builds. Add Parallel or Sonar API at the layer that needs orchestration; keep Scavio at the data layer.
