AI API Router Directory

AnyAPI is a commercial multi-model API aggregation gateway providing access to 400+ models via a single key. It offers a generous free tier for developers and scales to high-volume enterprise plans, supporting models from OpenAI, Anthropic, and open-weights families.

Free tier $0/mo: 100K tokens/day (~100 credits/day, 1 credit≈1K tokens), ~20 RPM / 200 RPD, free and basic models only, no card. ≈$3/mo blended at $1 per 1M tokens.

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.

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.

DGrid AI is a decentralized AI network that routes requests across a distributed mesh of nodes. It features an OpenAI-compatible gateway and is integrated into tools like Chatbox and Claude Code. Operates with on-chain transparency.

DeepInfra is an OpenAI-compatible inference cloud for open-weight models, with per-token rates published on a single pricing page. Examples from that page: DeepSeek-V4-Flash-0731 at $0.06 per 1M input tokens ($0.015 cached) and $0.18 per 1M output; Qwen3.5-9B at $0.10/$0.15; DeepSeek-V3.2 at $0.26/$0.38; Kimi-K3 at $2.85 per 1M input and $14.25 per 1M output; embeddings from $0.005 per 1M input tokens. Models without fixed token rates are billed on execution time, and custom LLM deployments are billed per minute of GPU uptime across A100 ($0.89/GPU-hour) through B300 ($4.89/GPU-hour). There is no free credit: the pricing page states you must add a card or pre-pay before you can use the service.

No free tier stated on official pages (checked 2026-09-16): deepinfra.com/pricing states that you must add a card or pre-pay before using the service, with no starter credit offered.

T3 Chat (t3.chat) is a multi-model chat client by T3 Tools, Inc. with model selection, web search, attachments and temporary chats, and its terms state that 'the Services are provided to you without charge up to certain usage limits, and usage in excess of these limits may require purchase of additional resources and the payment of fees'. The FAQ documents the usage meter as two buckets — a Base bucket that refills every 4 hours and an Overage bucket that refills on the monthly renewal date — using an illustrative example of 20 Base points plus 200 Overage points (220 total capacity). Price points themselves are not public: /pricing, /plans and /upgrade all return 404 and the terms direct users to the signed-in settings page for pricing details.

No dollar credit or numeric free allowance is published; the terms state only that the Services are 'provided to you without charge up to certain usage limits', with pricing on the signed-in settings page (t3.chat/terms-of-service, checked 2026-09-16).
