AI API Router Directory

Pollinations.ai is a Berlin-based open-source platform providing a signup-free, OpenAI-compatible API for text, image, and audio generation. It aggregates multiple open-weights models (DeepSeek, Qwen, Mistral) and offers them for free to foster creative AI development.

Basic use needs no signup and no API key; new Pollen credit system gives ~1.5 Pollen/week free, with some models/higher limits requiring an account or paid tier. Pollen has no published USD rate - not quantifiable.

ChatAnywhere is a widely used free LLM relay. Users bind a GitHub account to get a free API key and access GPT-4o, Claude, and Gemini models through an OpenAI-compatible interface, optimized for access from mainland China.

GitHub-bound free key: 10,000 points/day with per-model caps (GPT-5/4o/4.1 5/day, DeepSeek 30/day, mini models 100/day, ~200 req/day total) ≈ $2/mo; personal non-commercial use only.

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.

Devin, built by Cognition, is an agentic software engineering product spanning Devin Desktop, a CLI, Devin Cloud agents, DeepWiki and the Devin API, aimed at multi-repo engineering work such as migrations, PR review, incident triage and scheduled chores. Its pricing page lists Free at $0 with "a light quota to code with agents", limited model availability, unlimited inline edits and unlimited Tab completions, then Pro at $20/month, Max at $200/month for significantly higher quotas, Teams at $80/month for the team plan plus $40/month per full dev seat, and Enterprise by contact. Paid plans come with a usage allowance that refreshes daily and weekly, and usage beyond the allowance is purchased and consumed at API pricing.

Devin Free is $0 with a light agent quota, limited model availability, unlimited inline edits and unlimited Tab completions (devin.ai/pricing, checked 2026-09-16).

Adapta One (adapta.org / agent.adapta.one) — Brazilian multi-model AI subscription ('maior ecossistema de IA generativa do Brasil') bundling 15+ chat and image models (GPT, Claude, Gemini, DeepSeek, Qwen, Llama, Grok, Kimi, Flux, Nano Banana, etc.) in one chat with documents/spreadsheet analysis. Unofficial browser/cookie integration.

Flat R$99/user/month (≈US$18) with unlimited access to the bundled models; annual option R$1,428/year (12× R$119 with 2+ seats).

Chutes is a decentralized serverless AI inference marketplace on Bittensor (Subnet 64). It provides an OpenAI-compatible API for deploying and scaling open-source models using high-performance VLLM templates, with per-token pricing and optional monthly subscription plans.

Official announcement 2026-02-27: $5-deposit 200-requests/day plan closed to new users, fully retires 2026-03-15; now pay-per-token (or GPU by the second). Bittensor-subsidized cheap models are not a free tier.

Kiro (AWS) - agentic IDE powered by Amazon Bedrock; credit-based usage: Free (50 credits/mo, rate-limited) plus Pro/Pro+/Pro Max/Power; per-model credit multipliers (e.g. GPT-5.6 Sol 2.4x, Claude Opus 4.5 2.2x, Qwen3 Coder Next 0.05x); USD 20 sign-up bonus on free tier; context windows 200K-1M per model.

Add-on credits approx USD 0.04/credit per third-party (morphllm) - not official AWS pricing; official per-credit USD value not published in fetched sources.

NavyAI (api.navy) is a unified AI API gateway providing access to 150+ models through flat-rate subscription plans with daily token quotas. It offers an OpenAI-compatible interface, 'Login with Navy' OAuth for BYOP workflows, and plans ranging from a basic free tier to high-volume 'Apex' tiers.

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

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.
