AI API Router Directory

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.

Electron Hub provides a unified API to 600+ models, including premium frontier models (GPT, Claude, Gemini). It offers weekly credit refills on both free and paid subscription plans, plus permanent top-ups.

$0.25 weekly credits on the Free plan.

DXNT (DX Token) is an AI model API gateway providing unified access to GLM, Kimi, MiniMax, and DeepSeek. It offers high compatibility with IDEs and agents, featuring smart routing and MCP support. Details were checked against the provider's own page at dxnt.com.

100+ free calls daily on unified entry.

GitLab Duo is GitLab's set of AI features across the software lifecycle, including AI chat and code suggestions in the IDE, agentic chat, foundational agents and flows, a custom agent catalog, model selection and MCP integrations. GitLab's pricing page lists GitLab.com Free at $0/user/month with up to 5 users in a private top-level group, 400 compute minutes per month, 10 GiB storage and static application security testing, but states plainly that on Free "AI features can be accessed via the purchase of GitLab Credits add-on". Included AI credits appear only on paid tiers, shown as a limited-time promotional offer: $12 GitLab Credits per user/month on Premium ($29/user/month billed annually) and $24 per user/month on Ultimate, with GitLab Credits priced at $1 per credit.

GitLab.com Free is $0/user/month but includes no AI credits: the pricing page states AI features on Free are accessed only by purchasing the GitLab Credits add-on at $1 per credit, so the free AI grant is zero (checked 2026-09-16).

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.

LLM7.io is an open-source AI API gateway providing unified access to leading models like GPT and DeepSeek. It stands out for its unique anonymous access tier, allowing developers to test models without registration, and a registration-based free tier with higher limits.

Free relay: ~30 RPM anonymous, rising to ~120 RPM with free token from token.llm7.io (20/min, 100/h sub-caps); base URL api.llm7.io/v1 with api_key 'unused'. No token quota published → no USD estimate.

LaoZhang AI is an enterprise-grade AI API integration platform reselling over 200 models from OpenAI, Anthropic, and Google. It provides an OpenAI-compatible interface, invoice support for businesses, and a small signup credit ($0.05) for testing.

Perplexity's API blends request and token pricing: Search API at $5 per 1,000 requests; Sonar at $1/$1 tokens plus a $5–$12 per-1K request fee that scales with search depth; and the new Agent API serving OpenAI, Anthropic, Google and xAI models at direct provider rates with no markup, plus per-invocation tool pricing (web_search $0.0025). Sonar is sunset after September 27, 2026 — the Agent API is the successor.

No free tier on the API (checked 2026-09-16). Consumer Pro/Max plan credits (35K bonus + 10K monthly) apply to the app, not the API.

TheOldLLM (theoldllm.vercel.app) is a free, browser-based multi-model AI workspace for comparing leading models, chat, file/image analysis, web research, and study tools. Standard models need no account; frontier-tier models require a verified email, and rate limits apply.
