Overview
Hanzo AI is a commercial multi-model aggregator with a unified OpenAI-compatible endpoint and a no-card daily free API pool alongside paid models.
Free quota
The personal Free plan requires no card. Official documentation states 50 requests per day on free models plus 50 Kai decisions per day; excess requests return 429 and the allowance resets daily.

- Official documentation clearly specifies https://api.hanzo.ai/v1, bearer keys, and OpenAI-compatible examples.
- The free plan requires no card, and the quota, 429 behavior, and allowance endpoints are documented.
- The public catalog is broad; the probe found 300 models and 57 free entries.
- Core routing implementation and API behavior can be inspected in public GitHub repositories.
Cons
- The free tier is limited to selected models and a daily request pool; other models are metered or require paid plans.
- Public code says some free routes depend on a shared OpenRouter account pool, which may inherit shared upstream quotas and congestion.
- Long-term independent community reports are sparse; most evidence comes from Hanzo's own docs, website, and GitHub organization.
- The catalog and free-model count change dynamically, and the probe count does not exactly match the website's current display.
Risk flags
- The free plan is a daily capped pool and returns 429 at the limit, making it unsuitable for sustained concurrency or a production SLA.
- The public implementation says free routes use a shared OpenRouter key pool, so availability may inherit OpenRouter account-level limits and upstream outages.
- As a multi-model aggregator, Hanzo receives request content and may forward it to third-party providers; sensitive data requires careful review of privacy and supply-chain terms.
- Free models, allowance, and routing can change dynamically; check live /v1/models, /v1/allowance, and billing-tier data before use.
- Independent community reputation samples are insufficient; first-party documentation and repositories are not substitutes for third-party reliability validation.
Community reputation
Hanzo has a complete website, API documentation, public repositories, and a clearly stated free limit, providing strong evidence that the API is genuine and callable. However, searches found too few long-term Reddit, V2EX, Linux.do, or NodeSeek user reports; reputation evidence is dominated by first-party sources and does not establish long-term reliability or support quality.
Recommendation
It is a reasonable limited-free-API candidate within a commercial aggregator. Validate live models, remaining daily allowance, and rate limits with small non-sensitive workloads; production use should monitor 429 responses and maintain a fallback provider rather than treating the free tier as an SLA.
