Billing & Hybride C credits

Billing — walkthrough

Video walkthrough coming soon.

Hypex bills different from most agentic IDEs. You can pay $0 with your own API key, or $20 if you want us to handle keys, billing, and proxying. No quota lottery, no opaque "fast requests", no 100% markup.

How billing works

• Pro $20 / mo — includes $15 face-value of Anthropic API credits at cost price. As long as your monthly usage stays inside that envelope, you pay 0% markup on inference. The remaining $5 covers infrastructure: cloud sync, MCP marketplace hosting, observability, and the convenience of not managing keys.
• Overage opt-in (+15%) — if you blow through the $15 of face-value credits before renewal, you can flip on overage in /account. We bill the actual Anthropic cost + 15%. For comparison, some credit-based competitors charge around $0.04 per credit on overage which works out to roughly 100% markup.
• Toggle overage off — if overage is disabled and you hit the cap, you have three options: BYOK fallback (paste your own Anthropic key, plan keeps Pro features), top-up (one-shot pack), or wait for monthly renewal.
• Top-ups expire 12 months FIFO — top-up balance is consumed before face-value credits each month, oldest dollars first.

Hybride C — how a single call is metered

Hybride C is the engine behind the no-markup-while-in-budget guarantee. Here's what happens when you press Enter on a turn:

1. Step 1 — Pre-flight estimate. The worker computes a worst-case cost for the request (input tokens already known, output tokens assumed at max_tokens). If your balance < estimate, the call is blocked with a 402 before it even reaches Anthropic.
2. Step 2 — Stream open. If balance covers worst-case, the worker proxies the request to Anthropic and streams SSE back to your IDE in real time.
3. Step 3 — Real cost from message_delta.usage. When the stream completes, Anthropic sends the actual input/output/cached/cache-write token counts. The worker multiplies by ANTHROPIC_PRICES to get the true cost in cents.
4. Step 4 — In-budget = zero markup. If real_cost ≤ remaining_face_value, the worker debits exactly real_cost from your face-value envelope. You paid the same as if you'd been BYOK.
5. Step 5 — Over-budget = +15% on the overflow. If the call straddles the envelope, only the portion in excess is marked up by 15%. The in-budget portion stays at cost. If overage is disabled, the call falls back to the cap-hit flow above.

BYOK mode

Don't want to pay Hypex for inference at all? Drop your own Anthropic key in Settings → Providers → Anthropic API key. The worker proxies your traffic directly using your key — Anthropic bills you on their side, Hypex bills you $0. BYOK is fully supported on the Free tier; you keep ghost completions, agent profiles, plan mode, Ollama, and WDK scaffold/build for free, forever.

Local mode (Ollama)

Ollama is wired through Hypex's integrated model gallery — pick from 7B to 70B locally, one click install, no cloud, no credits, no metering. Runs offline and never touches the Hypex worker. Perfect for sensitive code, airgapped envs, or simply not wanting to pay a cent.

How model cost is computed

The worker reads token counts from the Anthropic SSE response and multiplies by the per-million-token rates from the ANTHROPIC_PRICES table (refreshed quarterly from claude.com/pricing#api).

cost_cents = (input * INPUT_RATE
            + output * OUTPUT_RATE
            + cached_read * CACHE_READ_RATE
            + cache_write * CACHE_WRITE_RATE) / 10_000

Current rates (2026-04-25):

• Opus 4.7 — $5 in, $25 out, $0.50 cached read, $6.25 cache write per 1M
• Sonnet 4.6 — $3 / $15 / $0.30 / $3.75
• Haiku 4.5 — $1 / $5 / $0.10 / $1.25
