AI API Router Directory

Blackbox AI now presents itself as enterprise inference rather than a consumer coding tool: its pricing page shows a single Enterprise plan with custom, annual, purchase-order committed spend and no free or individual tiers. Pricing is per token against published list rates across a 300+ model catalog served from one OpenAI-compatible endpoint, for example deepseek-v4.1-flash at $0.15 input / $0.60 output per 1M tokens and kimi-k3 at $3.00 / $15.00 per 1M, with commitments drawn down as usage is consumed and spend alerts at 75% and 90%. The same pages state end-to-end encryption on every connection, contractual zero data retention, PII removal before prompts reach closed models, dedicated single-tenant deployment and implementation included at $0 with a forward-deployed engineer.

No free tier stated on official pages (blackbox.ai, blackbox.ai/pricing and docs.blackbox.ai all present enterprise per-token commits only, checked 2026-09-16).

Huancheng Public API is a high-concurrency AI model router based on the New-API framework. It aggregates multiple upstream providers including OpenAI, Anthropic, and Google, offering a stable and low-latency endpoint for Chinese and global developers with real-time usage monitoring.

No public free-tier information found in the source reference; treat free-tier availability as unverified rather than confirmed absent.
