AI API Router Directory

token.sensenova.cn is the official Token Plan for SenseTime's SenseNova multimodal AI platform. During its public beta, it offers generous free quotas for models like SenseNova 6.8 Flash Lite and U1 Fast, suitable for complex office workflows.

Free public beta (extended to end of July): 1,500 calls/5h per model (verified: 60k points/5h on token-plan page); ~7,200 calls/day ~ $200/mo equivalent at ~1K tokens/call. Phone signup, up to 20 API keys.

OpenInference - open-source LLM relay with a single OpenAI-compatible endpoint (Anthropic-format root also available at https://api.openference.com/), API-key auth, automatic provider failover and a zero-data-retention option; free to start, paid plans from USD 1/mo; documented per-model on-demand USD/1M pricing on openference.com/models.

Free plan: 3-day trial with open-source models — no credit card required

VSLLM (Weiyun Model Open Platform) is a commercial AI API relay gateway that aggregates multiple large models. It is OpenAI-compatible and features a daily auto-refreshing free quota for new sign-ups. Claims to offer highly competitive, transparent pricing based on actual token usage.

Free subscription auto-refreshes daily without claiming: ~20 API calls + ~100K tokens/day (non-cumulative, reset next day) ~ $3/mo at $1/1M tokens; also GitHub-star and daily check-in reward activities.

ClinePass — Cline's flat $9.99/month subscription giving 2-5x the usage (vs standard API rates) on a curated set of open-weight coding models from Z.ai, Moonshot AI, DeepSeek, MiniMax, MiMo, and Qwen. No separate provider accounts or API keys needed; usable with other agents via the ClinePass API key. Separate from Cline's pay-as-you-go provider.

Flat monthly quota (2-5x API rate); not a per-token credit system.

Tencent CodeBuddy (CN) — Tencent's AI coding tool (IDE, plugin, CLI) backed by the TokenHub LLM platform. Proxies open-weight models from Z.ai, Moonshot, MiniMax, and DeepSeek under a monthly Token Plan (credit-based). Compatible with Claude Code, Codex CLI, Cline, Cursor, OpenCode, Kilo Code, etc. Note: pricing/model data below is from the documented Tencent Cloud Token Plan pages; CN endpoint specifics (copilot.tencent.com) were not separately fetchable, so this reflects the TokenHub plan as documented.

Credits are the unified billing unit; per-model deduction coefficients apply with DeepSeek peak/off-peak pricing (off-peak = half peak). No clean 1 credit = $X mapping documented, so no creditValueUsd.

NVIDIA NIM's hosted API (build.nvidia.com / integrate.api.nvidia.com) serves a broad catalog of open-weight models — Nemotron, Llama, Qwen, DeepSeek, GLM and more — in an OpenAI-compatible shape, with a permanent free tier: API key at sign-up, no card, 40 requests/minute by default (200 RPM granted on request, per NVIDIA's developer forums).

Free tier is rate-limited (40 RPM default, 200 on request) rather than credit-based — no USD value to quantify.

OpenVecta provides an AI model API with an OpenAI-compatible endpoint. It focuses on simplicity and ease of use, with reports of a free tier or trial credits available for new users. Details were checked against the provider's own page at openvecta.com.

Free credits on signup for OpenAI-compatible inference across LLMs, embeddings, and reasoning models

Regolo AI provides scalable serverless AI infrastructure with a focus on privacy and zero data retention. It serves popular open-source models (Llama, Mistral, Qwen) via an OpenAI-compatible API, offering monthly token capacity plans and a flexible free trial.

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

TGhan (Xiao Yu Yun API) is a feature-rich AI API relay providing unified access to over 30 LLM providers including OpenAI, Claude, and Grok. It offers professional features like empty-response compensation, transparent usage logs, and multi-protocol support optimized for high stability.

Confirmed paid-only via direct /api/pricing check: 49 models, all paid (fixed-price quota_type=1 or per-token model_ratio>0); zero free-price entries. Top-up is via third-party redemption codes.

ZCode is Zhipu's official coding client for the GLM Coding Plan sold on bigmodel.cn, whose personal tiers are listed in CNY: ¥94.4/month (list ¥118) with 10,000 credits per week, ¥430.4/month (list ¥538) at six times the Lite allowance, and ¥862.4/month (list ¥1078) at fourteen times, each unlocking Claude Code, Codex, Cursor, OpenCode, Cline, Kilo Code and AutoClaw, with ZCode subscribers receiving 150% quota. The platform's API price list shows GLM-5.3 at 8 CNY per million input tokens and 28 CNY output, GLM-5.3-Flash at 0.8/2.8 CNY, GLM-TTS at 2 CNY per 10,000 characters, and Batch calls at half the standard price. New registered users receive 20 million tokens, and GLM-4.7-Flash (200K context) and GLM-4.6V-Flash are listed as free API models.

Allowance is 20,000,000 tokens for newly registered users ('新用户注册得 2000万 Tokens') plus up to 200 million tokens via referral on bigmodel.cn/pricing; no CNY or USD cash value is stated for the grant (checked 2026-09-16).
