AI API Router Directory

Hajimi API (api.gemai.cc) is a Chinese third-party relay aggregation platform. It specializes in routing requests to Claude, Gemini, and GPT models through a unified OpenAI-compatible endpoint, primarily catering to users requiring simplified access to international models.

New users get 100 units of balance by default (community figure ~¥500 (≈$74.39)), QQ-email signup only; there is a daily check-in farming crowd; 'limited perk' zero-priced models can be delisted anytime.

AeroLink (aerolink.lat) is a commercial AI API gateway and relay service that routes multiple coding assistants and automation tools through a single key. It offers tiered subscription plans with rolling usage windows and claims access to high-end models like Claude Opus 4.8.

Starter plan offers a 1-week free trial included in the promo.

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.

PiAPI offers a model aggregation platform with native API formats. It provides subscription tiers that include bonus credits and pay-as-you-go usage. New users receive a $0.50 starting credit. Details were checked against the provider's own page at piapi.ai.

No public free-tier information found (researched 2026-08-29).

Inner AI (innerai.com / app.innerai.com) is a multi-model AI productivity app (chat, image/audio/slide generation, custom assistants). Access via this route is an unofficial web-cookie integration (token cookie + account email). Official pricing page documents Lite and Pro plans with GPT-5 Mini/DeepSeek 3.1 +5 fast models, GPT-5/Claude 4.6 Sonnet +5 advanced models, and credit-based generation (Nano Banana, ElevenLabs, Gamma +25). Third-party sources report a 7-day free trial/money-back guarantee rather than a perpetual free tier.

Derived: Pro plan ($15/mo) includes 10,000 monthly generation credits (pt innerai.com/pricing) -> ~$0.0015/credit.

Adapta One (adapta.org / agent.adapta.one) — Brazilian multi-model AI subscription ('maior ecossistema de IA generativa do Brasil') bundling 15+ chat and image models (GPT, Claude, Gemini, DeepSeek, Qwen, Llama, Grok, Kimi, Flux, Nano Banana, etc.) in one chat with documents/spreadsheet analysis. Unofficial browser/cookie integration.

Flat R$99/user/month (≈US$18) with unlimited access to the bundled models; annual option R$1,428/year (12× R$119 with 2+ seats).

Anthropic's Claude API is per-token with no free tier: Fable 5.1 $10/$50, Opus 5 $5/$25, Sonnet 5 $2/$10 and Haiku 4.5 $1/$5 per 1M in/out, with the full 1M-token context at standard pricing on 4.6+, a 50% batch discount, prompt-caching reads at 0.1× input (0.025× on Fable 5.1), 1.1× US-only inference, and itemized server-tool pricing. Consumer plans (Free/Pro/Max) are a separate product.

No free tier on the API (verified 2026-09-16) — first requests bill at per-token rates. The claude.ai Free plan is a separate consumer product with usage limits, not API access.

Antigravity CLI (agy) — the terminal TUI for Google Antigravity 2.0, replacing Gemini CLI. Shares the same agent backend as the Antigravity IDE (incl. Claude models). Authenticates via Google OAuth. Free 'Individual' tier with weekly rate limits; higher limits via Google AI Pro/Ultra plans. No bring-your-own-key support.

Overage billed via purchased Google AI credits at Gemini Enterprise Agent Platform consumption pricing (not per-token fixed).

Api.airforce is a unified AI model aggregator reselling access to 100+ models from Anthropic, OpenAI, and xAI. It offers a large selection of free models (including Grok-3 and Claude 3.7) alongside paid subscription tiers for higher throughput.

55 free tier models including Grok-3, Claude 3.7, Qwen3, Kimi-K2, Gemini 2.5 Flash, DeepSeek-V3

Arena.ai (formerly LMArena / Chatbot Arena, lmarena.ai) is a free, anonymous multi-model chat + blind A/B voting service that powers the public LLM/image/code leaderboards. It rotates a large lineup of frontier and open models. This route is an unofficial web-cookie integration (arena-auth cookie, optional Cloudflare clearance/reCAPTCHA tokens); the site also supports anonymous sessions but automated access is rate-limited and subject to bot checks.

A free tier is available; the exact credit value is not quantified.

Auggie is Augment Code's free, terminal-based agentic coding CLI (npm i -g @augmentcode/auggie) that runs context-aware agents locally with interactive and headless modes. It is multi-model (Claude, GPT, or bring-your-own-key); the broader Augment 'Cosmos' platform is the company's enterprise offering.

Free CLI tier; enterprise/Cosmos pricing not publicly quantified on the fetched pages.

Claude's consumer app is sold on a plan matrix published at anthropic.com/pricing. The Free column includes chat on web, iOS, Android and desktop, Sonnet and Haiku model access, a 200k-token context window, web search, artifacts, memory, skills, connectors, voice mode, incognito chats and file creation and editing through code execution, while Opus, Fable, Claude Code, Projects, Research, Claude in Chrome and the Microsoft 365 and Outlook integrations are all marked as not included. Anthropic states only that usage limits apply and does not publish a numeric message or token cap for the Free plan.

No free tier stated on official pages (checked 2026-09-16) as a credit: the consumer Free plan is a listed plan tier but no allowance or numeric cap is published, and the API docs state only that new API users receive a small amount of free credits without quantifying them.

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.

Duck.ai is DuckDuckGo's free, private AI chat (also surfaced at duckduckgo.com/duckchat). It requires no account and offers chat, voice, image, and search across models including OpenAI GPT (e.g., '5.6 Luna') and Claude.

Free anonymous chat; an 'Upgrade'/Pro option exists but pricing not quantified on fetched pages.

Juzi AI (api.juziai.cc) is a Chinese commercial-aggregator relay built on the New-API framework. It aggregates high-end models like GPT-5 and Claude Opus by leveraging various upstream account pools, offering pay-as-you-go access to users in mainland China.

Free quota negligible: daily check-in after 10 calls grants 5–20 quota (quota_per_unit=500000 ≈ $1 per 500K quota) → well under $0.01/day; most model_ratio=0 models are pay-per-call. Not quantifiable.

NanoGPT (nano-gpt.com) is a large-scale AI API aggregator providing access to 1,000+ models with strict 'list price' pay-as-you-go billing. It supports OpenAI-compatible endpoints for text, image, and video models, adding a flat 5% fee only for opt-in features like BYOK or pinned providers.

T3 Chat (t3.chat) is a multi-model chat client by T3 Tools, Inc. with model selection, web search, attachments and temporary chats, and its terms state that 'the Services are provided to you without charge up to certain usage limits, and usage in excess of these limits may require purchase of additional resources and the payment of fees'. The FAQ documents the usage meter as two buckets — a Base bucket that refills every 4 hours and an Overage bucket that refills on the monthly renewal date — using an illustrative example of 20 Base points plus 200 Overage points (220 total capacity). Price points themselves are not public: /pricing, /plans and /upgrade all return 404 and the terms direct users to the signed-in settings page for pricing details.

No dollar credit or numeric free allowance is published; the terms state only that the Services are 'provided to you without charge up to certain usage limits', with pricing on the signed-in settings page (t3.chat/terms-of-service, checked 2026-09-16).
