AI API Router Directory

Helyx markets itself as a unified OpenAI-compatible API gateway for frontier models (Claude Opus 5, Claude Haiku 4.5, GPT-5.4 Nano, Gemini, Kimi, DeepSeek) claiming 50+ models behind one endpoint, with a published rate card of five active models including DeepSeek-V4 Pro at $0.400 in / $0.750 out per 1M tokens (50% off its $0.800/$1.50 list) and MiniMax M3 at $0.300/$1.200. Signup is Google or GitHub with no password, and the account is credited with $10.000000 free: $2.000000 instantly plus $8.000000 released on request. Paid top-ups are crypto-only (USDT, USDC, BTC, ETH, TRON) and every deposit is doubled ($5 pays $10 credit, $25 pays $50), with credits stated to never expire and no subscriptions or daily caps. The domain in this listing, helyx.ai, is dead - it returns a 404 DEPLOYMENT_NOT_FOUND from Vercel - and the live Helyx AI site is served from helyxai.space.

$10.000000 signup credit ($2.000000 instant, $8.000000 released on request) as stated on the helyxai.space homepage and pricing page; the $10 figure is the operator's own published grant, not a conversion.

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.

FastRouter is a high-performance gateway for AI model routing, comparison, and operations. It supports 200+ models via an OpenAI-compatible API with intelligent cost optimization and failover. Details were checked against the provider's own page at fastrouter.ai.

Free credits included to build, test and explore.

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.

LLM Gateway is a unified AI API router that allows access to over 200 models from multiple providers. It features a 'Hosted Free' plan where free models are accessible with a 5 requests per 10 minutes limit when no credits are available in the account.

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.

Poe is Quora's multi-model chat product that aggregates GPT, Claude, Gemini, Grok, Kimi and image/video/audio bots behind one subscription and one points balance rather than separate provider plans. Official subscription plans are annual: $49.99/year ($4.17/month) for 10 thousand points per day, $199.99/year for 660 thousand points per month, $499.99/year for 1.65 million, $999.99/year for 3.3 million and $2,499.99/year for 8.25 million points per month, with an add-on rate of $30 per 1M points that subscribers can buy for API or one-off use. Non-paying users receive points daily that reset every 24 hours and never roll over; Poe's help centre states subscriptions start at $4.99/month.

Poe gives non-paying users daily compute points that reset every 24 hours, but no official page fetched states the daily quantity, and poe.com/pricing returns 404, so no dollar value is claimed (checked 2026-09-16).

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.

Zylo API provides a unified OpenAI-compatible gateway to models from Anthropic, OpenAI, Google, and more with zero token markup. Billing is based on base per-token rates deducted from a prepaid balance. A flat platform fee applies when adding credits.
