AI API Router Directory

RouterPark is a directory and monitoring site for unofficial and free AI model relays. It catalogues third-party Claude and GPT proxies, providing a dashboard for status and latency while offering its own unified entry point for multiple 'free' upstreams.

Directory is free/login-free; any.routerpark.com proxy (ANTHROPIC_BASE_URL) signup credit: site advertises $20 but probes report ~$2 (+~$10 for posting). Conservative: $2; quota depends on third-party relays.

Super NB (api.super-nb.me) is a Chinese AI API gateway providing OpenAI-compatible access to global LLM providers. It aggregates GPT and Claude models, offering a simplified top-up and usage experience for developers in the region through a New-API based interface.

Nodeloc partner post (2026-08-19): Nodeloc users get $2 signup credit plus weekly lottery and first-top-up promos; e7ai post mentions a claimable $50 subscription voucher. Core remains a paid top-up relay.

OpenRouter is a unified, OpenAI-compatible API aggregating hundreds of model providers behind one key. Free model variants (:free IDs) are genuinely free with documented platform caps — 20 requests/min and 50/day for accounts that have purchased under 10 credits, 1,000/day once you've purchased 10+ — while paid variants have no platform request cap. Fallback routing, per-key credit caps, and BYOK are built in.

:free models cost $0, no card; 20 req/min; 50 :free req/day with <10 credits, 1000/day after buying $10+ credits (verified FAQ; failed reqs count). ~$1.5/mo equivalent at 50 req/day, ~1K tokens/call.

Hvoy AI is a specialized diagnostic and directory site for third-party AI API gateways. It performs continuous latency, uptime, and model-adulteration testing to help developers benchmark and select relay providers. Mirrored at hvoyai.com.

The site is primarily a checker/comparison tool; minor perks: ~20 points on signup, ~10 points to claim one free token, ~20 points for sharing, plus an occasional ~5 CNY (≈$0.74) redeem code; it claims a small daily 'freebie' of reverse-proxied sonnet-4.6/gpt5.3 (e.g. ~50 sonnet4.6 calls/day), with no guaranteed quota or stability.

Agnes AI, developed by Singapore-based Sapiens AI, is an omni-modal AI platform offering indefinitely free access to core text, image, and video models. It supports OpenAI-compatible API keys and tiered 'Token Plans' for production-level throughput.

Advertised as indefinitely free core-model API with rate/volume caps; signup probe hints ~$1 starter credit (counted). Free tier reportedly sufficient for individual developers and demos.

~40 models offer daily free quotas that auto-refresh the next day (including some Claude/GPT/Gemini models); claims of sign-up bonus and 7-day no-questions refund are platform self-promotion — actual amounts per the console.

BazaarLink is a Taiwan-based AI aggregator providing access to 100+ models via an OpenAI-compatible API. It specializes in TWD billing and unified enterprise invoices. It offers a small signup credit and a persistent free model tier.

Signup trial credit ~$0.20 (probe, no card, no waitlist) counted; plus persistent free deepseek-v4-flash (~10 RPM / 150 RPD) and auto:free routing; PAYG at upstream list price after credit is spent.

Scaleway Generative APIs is a serverless, OpenAI-compatible inference service hosted only in Paris and billed per 1M tokens in euros. Published rates run from EUR 0.15/1M input and EUR 0.60/1M output for gpt-oss-120b, and EUR 0.15/EUR 0.35 for mistral-small-3.2-24b-instruct, up to EUR 1.80/EUR 5.50 for glm-5.2; whisper-large-v3 is metered per audio minute at EUR 0.003 with free output tokens, and embedding models are input-only at EUR 0.10/1M. Every new customer gets a free tier of 1,000,000 tokens, with billing starting at token 1,000,001.

1,000,000 free tokens per new customer, stated on the Generative APIs page; valued at the cheapest published input rate of EUR 0.15/1M (mistral-small-3.2-24b-instruct or gpt-oss-120b), which is roughly USD 0.16 - the grant is token-denominated, so actual dollar value varies by model.

ProRiseHub is a paid top-up relay built on the New API framework, OpenAI-compatible at /v1. Documentation states top-ups are converted at a rate of 1 RMB ≈ $0.15 USD credit, with several dozen zero-priced models.

Every account — including the Free plan — gets 10,000 Neurons per day free, resetting at 00:00 UTC; beyond that, the Paid plan bills usage. The catalog spans LLMs, embeddings, image and audio models and sits next to your Workers apps.

10,000 Neurons/day free on all plans (reset 00:00 UTC) ≈ $0.11/day ≈ $3.30/month at full use; overage $0.011 per 1,000 Neurons on the Paid plan.

Hugging Face Inference Providers routes one API key across 200+ models from multiple inference providers at the providers' own rates — no markup. Every user gets monthly credits ($0.10 on the Free plan; $2.00 PRO; $2.00/seat Team & Enterprise) applied automatically before pay-as-you-go; a BYOK mode routes through your own provider keys instead.

Official docs: $0.10/month Inference-Providers credits for Free users (PRO $2.00/month, Team/Enterprise $2.00/seat), credited monthly and applied before pay-as-you-go (confirmed 2026-09-16).

Nomic AI provides the Atlas Embedding API and open-weight models like nomic-embed. It offers a monthly free tier for its embedding API and is transitioning to focus on document AI for specialized industries.

Atlas embedding API free tier ~1M embedding tokens/month for evaluation and prototyping; ~$0.10/mo equivalent at Nomic embed pricing (~$0.10/1M tokens); paid beyond that.

SambaNova Cloud serves open-weight models (DeepSeek-V3.1, DeepSeek-V3.2, Meta-Llama-3.3-70B-Instruct, gpt-oss-120b, gemma-4-31B-it, MiniMax-M2.7 and MiniMax-M3) through an OpenAI-compatible endpoint at api.sambanova.ai/v1, priced per 1M tokens from $0.22 input / $0.59 output for gpt-oss-120b up to $3 / $4.50 for DeepSeek-V3.1 and V3.2. The free tier is defined by the absence of a payment method: 20 requests per minute, 20 requests per day and 200,000 tokens per day per model, on the five models listed in the free-tier tables. Linking a card moves the account to the Developer tier, which raises per-model limits and caps the account at 20M tokens per day across all models.

Free tier is a recurring daily allowance, not a USD credit: 200,000 tokens/day (20 RPM, 20 RPD) per the official rate-limits docs; 200k tokens at the cheapest published input rate of $0.22/1M (gpt-oss-120b) is about $0.04/day, while the same 200k at DeepSeek-V3.1's $3/1M input rate would be about $0.60/day.
