Not a prose engine: every Sonar answer runs a live web search and returns citations, which makes it the research sidekick — switch to it when a chapter touches real places, current events, or lore fact-checking, and keep another provider for the actual continuation. This page is the BYOK quick answer for Perplexity: key steps, direct console and pricing links, and the app-side notes that matter. Verified 2026-07-18.
Two links up front: get your key at the official console and check rates on the official pricing page. Prices and free quotas move; the official pages are authoritative.
The factory preset declares 1 modality flag for Perplexity. The models actually available come from the live catalog fetched in-app — catalogs move fast, and the flag only means the protocol wiring is ready.
| Modality | Used for |

The one universal host pitfall: the API host must include its full version prefix (this provider's exact form is in the notes below) — the app never appends /v1 for you.
Perplexity-specific notes
The preset host is https://api.perplexity.ai — deliberately without a /v1 prefix (chat/completions lives at the root), so don't add one yourself (/v1/chat/completions is a verified 404). Use sonar / sonar-pro / sonar-reasoning-pro as model IDs; the bill combines token pricing with a per-1K-request search fee ($5–14 by context tier), one more line item than pure token-priced providers.
No free tier: the API is its own prepaid system and requires a card plus purchased credits. Pro subscriptions used to include a $5/month API credit, but multiple reports say it was discontinued in early 2026 — don't build on it; the console balance page is the source of truth.
It's stored on your device only, under system-level encryption — never uploaded or synced to any Foreverse server. Requests go straight from your phone to the provider's official endpoint with zero markup. To revoke access, delete the key in the provider's console.
