AI API Router Directory

Lightning AI (LitAI) provides a unified gateway to frontier models through an OpenAI-compatible API. New users receive 40 million free tokens (approx. $15 in credits) to test models like Claude, GPT, and Gemini. Usage beyond the initial credit is billed as pay-as-you-go.

~30M free tokens per user per month (~15 credits = $15 value), no card required; credits refresh monthly and expire if unused; plus 1 free 4-CPU Studio and 10GB Drive.

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.

DeepSeek's official API serves the current V4.1-Flash and V4-Pro models with 1M-token context and 384K max output, from $0.15/$0.60 per 1M in/out off-peak (Flash) — peak hours bill at 2x, cached input drops to $0.003/M. One key exposes both an OpenAI-compatible and an Anthropic-compatible endpoint, and sign-up grants a free token balance that is deducted before any top-up.

Free 'granted balance' of ~5M tokens at sign-up (deducted before top-ups per official billing rules); $0.70 is an estimate at V4-Flash off-peak rates.

Qoder - AI coding IDE (Agent/Quest modes) with credit-based plans; Free tier (2-week Pro trial with 300 credits, limited completions/NES, BYOK); Pro/Pro+/Ultra; Credit Pack; per-model cost varies by tier multiplier (Auto approx 1.0x, Ultimate approx 1.6x, Performance approx 1.1x, Efficient approx 0.3x now free for paid, Lite free); context options 200K/400K/1M.

Plan quota approx subscription value (approx USD 0.01/credit). qoder.com/pricing headline shows Pro at 4,000 credits incl. a 2,000 first-purchase bonus; docs base is 2,000 credits/mo.

Blackbox AI now presents itself as enterprise inference rather than a consumer coding tool: its pricing page shows a single Enterprise plan with custom, annual, purchase-order committed spend and no free or individual tiers. Pricing is per token against published list rates across a 300+ model catalog served from one OpenAI-compatible endpoint, for example deepseek-v4.1-flash at $0.15 input / $0.60 output per 1M tokens and kimi-k3 at $3.00 / $15.00 per 1M, with commitments drawn down as usage is consumed and spend alerts at 75% and 90%. The same pages state end-to-end encryption on every connection, contractual zero data retention, PII removal before prompts reach closed models, dedicated single-tenant deployment and implementation included at $0 with a forward-deployed engineer.

No free tier stated on official pages (blackbox.ai, blackbox.ai/pricing and docs.blackbox.ai all present enterprise per-token commits only, checked 2026-09-16).

Hyper (by Charm) is an AI inference solution purpose-built for coding. It manages its own infrastructure to optimize open-source coding models. It provides 100 free Hypercredits monthly on signup. Details were checked against the provider's own page at hyper.charm.land.

No public free-tier information found in the source reference; treat free-tier availability as unverified rather than confirmed absent.

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.

Tencent CodeBuddy (CN) — Tencent's AI coding tool (IDE, plugin, CLI) backed by the TokenHub LLM platform. Proxies open-weight models from Z.ai, Moonshot, MiniMax, and DeepSeek under a monthly Token Plan (credit-based). Compatible with Claude Code, Codex CLI, Cline, Cursor, OpenCode, Kilo Code, etc. Note: pricing/model data below is from the documented Tencent Cloud Token Plan pages; CN endpoint specifics (copilot.tencent.com) were not separately fetchable, so this reflects the TokenHub plan as documented.

Credits are the unified billing unit; per-model deduction coefficients apply with DeepSeek peak/off-peak pricing (off-peak = half peak). No clean 1 credit = $X mapping documented, so no creditValueUsd.

Freebuff is a specialized AI API relay often associated with developer automation and coding tools. It provides programmatic access to high-end models for free or via community-shared keys, primarily aimed at script-based integration and tool builders.

NVIDIA NIM's hosted API (build.nvidia.com / integrate.api.nvidia.com) serves a broad catalog of open-weight models — Nemotron, Llama, Qwen, DeepSeek, GLM and more — in an OpenAI-compatible shape, with a permanent free tier: API key at sign-up, no card, 40 requests/minute by default (200 RPM granted on request, per NVIDIA's developer forums).

Free tier is rate-limited (40 RPM default, 200 on request) rather than credit-based — no USD value to quantify.

Naga.ac is a unified AI aggregator providing access to over 240 models via one OpenAI-compatible API. It offers a free tier with 100 requests per day and a pay-as-you-go model with competitive rates, occasionally lower than direct provider pricing for select models.

OpenAdapter is an AI model API providing access to models like DeepSeek, Qwen, and GLM through an OpenAI-compatible endpoint. It focuses on easy integration by allowing standard clients to switch base URLs.

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.

Free credits on signup for OpenAI-compatible inference across LLMs, embeddings, and reasoning models

Routeway is an AI model router and gateway that provides a unified Bearer-auth interface for multiple global and domestic models. It simplifies integration for developers by handling model-specific protocols and providing a consistent management dashboard for keys and usage.

Shawn AI (肖恩AI) is a community-driven API relay station aimed at roleplay and tavern users. It aggregates hundreds of models including Claude 4.7 and GPT-5.5, offering free daily points and signing bonuses. It features a transparent point-deduction system and recovery for failed generations.

Uses a 'points' system (5000 on signup, 1000-3000 daily check-in) which does not have a fixed USD conversion rate.

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.

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.
