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.

OpenAI Codex is the coding agent that runs across ChatGPT, an IDE extension, the CLI and cloud environments on a single ChatGPT account, with cloud worktrees, scheduled background tasks, Skills and code review. The Codex pricing documentation lists Free at $0/month for "quick coding tasks", Go at $8/month, Plus at $20/month, Pro from $100/month, Business at $20/user/month billed annually ($25 monthly, minimum 2 users) and Enterprise/Edu by contact, plus an API-key route billed at API rates. Usage is measured as messages per five-hour period that vary by model: on Plus, the documented ranges run from 250-2,000 messages for GPT-5.6 Luna down to 5-45 for GPT-6 Astra, and OpenAI states these are estimates rather than fixed limits.

Codex Free is $0/month, described as "Explore Codex capabilities on quick coding tasks"; no fixed free message count is published (Codex pricing docs, checked 2026-09-16).

Command Code is an AI coding API aggregator offering subscription-based access to a curated selection of open and premium models. It simplifies key management for developers by providing a unified gateway with generous monthly usage limits.

OpenAI Codex CLI — OpenAI's terminal coding agent (also web/IDE). Authenticates via ChatGPT OAuth or an API key. Model lineup (as of mid-2026): GPT-6 Astra, GPT-5.6 (Sol/Terra/Luna), GPT-5.5, GPT-5.4 / 5.4 mini, plus gpt-oss-120b; GPT-5.3-Codex-Spark is a Pro-only research preview. Plans: Free, Go ($8), Plus ($20), Pro 5x ($100) / 20x ($200); API-key mode is pay-as-you-go at API rates.

ChatGPT plans use credit-based usage allowances (credits per 1M tokens, e.g. GPT-5.6 Sol 100/10/500); not a fixed $ credit value. API-key mode billed at standard OpenAI API token rates.

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.

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).

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.

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.

Free chat interface; access/rate limits vary by account status, no USD credit.
