Building an AI app or coding with Claude Code / Cursor? The first decision is which API to connect. There are three paths: official APIs, relays like Zivv, and other third-party relays. Prices can differ by tens of times, and stability and features vary just as much. This article breaks down all three across five dimensions so you choose right the first time.
Three Solutions at a Glance
1. Official APIs (Claude, OpenAI, Google)
Direct connection to Anthropic, OpenAI, and Google endpoints — the most "orthodox" option.
Pros:
- Maintained by the provider, shortest path, highest stability
- New models and features land first (e.g. Anthropic prompt cache, batch API)
- Strongest data compliance and privacy — fits enterprises with hard security requirements
Cons:
- USD billing, requires an international credit card, with currency conversion overhead
- High signup and payment barrier
- Strict rate limits: new Claude accounts have low RPM/TPM, easy to hit under heavy use
- Pure API — no team management, budget control, or usage analytics
2. Zivv (This Solution)
Maintained by a local team, built for developers and teams, adding engineering capabilities on top of the official protocols.
Pros:
- ¥1.2 / 1M tokens unified price, 80%+ cheaper than official
- Direct CNY top-up, no credit card, no currency loss
- Claude unlimited: 24/7 subscription account pool rotation, auto-failover, fully transparent to users
- 100+ models with a single key; OpenAI / Anthropic / Gemini protocol compatible
- Team management, budget control, per-member usage analytics — rare among peers
- Real-time support via Telegram community
3. Other Relays
The many small relays and individual resellers on the market.
Common issues:
- Chaotic pricing: big differences across models and channels, no transparency
- Poor stability: no SLA, frequent timeouts, disconnects, or quality degradation at peak
- Protocol incompatibility: only specific SDKs or formats supported, high migration cost
- No team features: usually individual accounts only
- No support: no one responds when things break, real risk of shutdown
Five-Dimension Comparison
| Dimension | Official API | Zivv | Other Relays |
|---|---|---|---|
| Price (Claude Sonnet) | $3~15/M | ¥1.2/M | ¥3~5/M |
| Payment | Intl. credit card | Direct CNY | Varies |
| Rate limits | Strict | Unlimited | Inconsistent |
| Protocol | Single official | OpenAI/Anthropic/Gemini | Usually single |
| Team management | None | Yes | Mostly none |
| Support | Tickets (English) | Real-time Telegram | Mostly none |
Cost Comparison: 10M Tokens/Month
Using Claude Sonnet, 10M tokens/month (split evenly input/output).
Scenario 1: Official API
- Input 5M × $0.003 = $15
- Output 5M × $0.015 = $75
- Subtotal $90, roughly ¥657/month after conversion
Scenario 2: Zivv
- 10M × ¥0.0012 = ¥12/month
- Saves ¥645 vs official
Scenario 3: Other Relays (¥3~5/M)
- 10M × ¥0.003~0.005 = ¥30~50/month
- Cheaper than official, but still 3~4× Zivv
Who Should Choose What?
Official API:
- Enterprise apps where security and compliance come first (finance, healthcare, government)
- Need the newest models and experimental features immediately
- Ample budget, indifferent to cost and payment friction
Zivv:
- Developers and startups, cost-sensitive
- Heavy Claude Code / Cursor users where unlimited rate is essential
- Need to switch flexibly across models with one key
- Have a team and need budget control and per-member analytics
Other Relays:
- Very specific custom requirements
- Already deeply locked into a platform
Conclusion
In short: for most developers and startups, Zivv saves around 90% while adding unlimited rate, one-key multi-model switching, and team management — none of which official APIs provide. Unless you have hard security/compliance constraints, Zivv is almost always the best value.
