AI API Router Directory

OCI Generative AI (now positioned as OCI Enterprise AI) is Oracle's managed service for pretrained and custom models, agents and governance on Oracle Cloud Infrastructure, with chat, embeddings, rerank, OpenAI-compatible APIs and an OCI Responses API. Oracle bills it through the public OCI price list, where rates are itemised per model: xAI Grok and Google Gemini entries are priced per 1,000,000 tokens (with cached-input and >200K-context variants), Cohere and Meta Llama endpoints per 10,000 transactions, and private replicas or fine-tuned models on Dedicated AI units per hour. New accounts get a US$300 cloud credit valid for 30 days plus ongoing Always Free services, but Generative AI is not among the AI services Oracle lists as having a free pricing tier.

Oracle Cloud Free Tier gives a US$300 cloud credit to spend within 30 days on all OCI services in addition to Always Free services, switching to pay-as-you-go or Always Free only afterwards (oracle.com/cloud/free/); OCI Generative AI itself is not listed among Oracle AI services with a free pricing tier.

Vertex AI serves Google's Gemini models through Google Cloud's paid API (aiplatform.googleapis.com), with project-level billing and a choice between global and non-global endpoints; the generative-AI pricing URL now renders as the Agent Platform (Gemini Enterprise Agent Platform) pricing page. Published list prices per 1M tokens: Gemini 3.8 / 3.7 / 3.6 Flash are on introductory pricing of $0.75 input and $3.75 output through December 31, 2026, rising to $1.50 and $7.50 on January 1, 2027, while Gemini 3.5 Flash-Lite is $0.30 input and $2.50 output and Gemini 2.5 Flash is $0.30 and $2.50. The Vertex pricing page states no standing free monthly token allowance for Gemini; Google's free-tier documentation instead gives $300 in 90-day Free Trial credit and a separate free tier for many Gemini models under the Gemini Developer API (AI Studio).

Google Cloud Free Trial gives $300 in Welcome credit valid for 90 days for eligible new billing accounts (cloud.google.com/free/docs/free-cloud-features); the Vertex generative-AI pricing page itself lists no free token allowance but does include 5,000 free grounding queries per month across Gemini 3 models.

Amazon Bedrock is AWS's model-API layer: 18 provider brands (Anthropic, OpenAI, Meta, Mistral, DeepSeek, Google, NVIDIA, xAI, Qwen, Amazon Nova and more) behind one AWS account, priced per 1M tokens with a 50% batch discount, tiered cross-region pricing and reserved/provisioned capacity. Bedrock itself has no standing free tier — new AWS accounts get $100 in credits at sign-up plus up to $100 more over a 6-month free plan.

New AWS accounts: $100 credits at sign-up + up to $100 earned over the 6-month free plan (aws.amazon.com/free, verified 2026-09-16). Bedrock itself has no standing free tier.

Google AI Studio gives free API access to Gemini models — free input and output tokens under per-model rate limits, not a depleting credit. Current-generation Flash models (including Gemini 3.8 Flash) are free-tier eligible. Paid tiers unlock higher limits, context caching, the 50%-off Batch API, and the most advanced models on the same API; free-tier data is used by Google to improve its products, paid-tier data is not.

Estimated based on high free-tier rate limits (RPD) vs paid input/output rates for equivalent usage.

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.

Serper: fast (1-2s) Google SERP API — web, news, images, places, scholar, patents, videos, shopping, autocomplete as structured JSON. Credit-based prepaid billing: 2,500 free credits on signup, $1.00/1k base dropping to $0.30/1k at volume; credits valid 6 months; failed requests not billed. (Official pricing page is 404 — figures corroborated across multiple independent 2026 sources.)

2,500 free signup credits × $1.00/1k base rate ≈ $2.50 (one-time, credits expire in 6 months).

SearchAPI: Google/Bing/Bing/30+ engines SERP API — structured JSON results in seconds; billed only for successful 200-status searches; 100 free requests at signup (no card); prepaid subscription plans $40-$5,000/mo (Developer 10k searches at $4/1k down to Octo 5M at $1/1k); rate limit = 20% of plan credits/hour; up to $2M legal protection guarantee.

100 free signup requests × $0.004/search (Developer plan rate $4/1k) ≈ $0.40 one-time value.

The Gemini app is free with a personal Google Account at 'standard limits'; Google's help centre states Gemini Apps use compute-based usage limits that refresh every 5 hours until a weekly limit is reached. Free accounts get a 32k-token context window and access to Gemini Flash-Lite, Flash and Pro models, while paid tiers raise limits (Google AI Plus 2x at $4.99/mo, AI Pro 4x at $19.99/mo, AI Ultra 5x or 20x at $99.99 and $199.99/mo) and lift the context window to 1M tokens on Pro and Ultra.

No monetary credit accompanies the free Gemini tier; Google states free access has 'standard limits' with a 32k-token context window, while paid Google AI plans are $4.99/mo (Plus), $19.99/mo (Pro) and from $99.99/mo (Ultra, 5x and 20x variants).

Google Jules is an asynchronous coding agent that clones a connected GitHub repository into a Google Cloud VM, presents a plan for approval, then returns a diff and pull request. The no-cost tier is stated as 15 tasks per day and 3 concurrent tasks, while Jules in Google AI Pro provides 100 tasks per day and 15 concurrent tasks and Jules in Google AI Ultra provides 300 tasks per day and 60 concurrent tasks. Jules is described as language agnostic but works best with JavaScript/TypeScript, Python, Go, Java and Rust projects.

The no-cost tier is stated on jules.google as 15 tasks per day and 3 concurrent tasks, described in Google's blog as 'Introductory access to Jules'; no USD credit is published and daily task caps do not convert to a dollar amount.

Google Programmable Search Engine (Custom Search JSON API): programmatic web/image search results from a configured Programmable Search Engine. 100 free queries/day, $5 per 1,000 additional queries up to 10k/day. IMPORTANT: service discontinues January 1, 2027 and is not available to new customers — legacy pricing applies only to existing customers.

Free tier is 100 queries/day ≈ 3,000/mo × $5/1k ≈ ~$15/mo equivalent if fully used, but the free allotment resets daily and is capped at 100/day; not a purchased credit grant, so left null.

Inference.net is a unified LLM gateway, observability and fine-tuning platform rather than an image or video vendor. Its pay-as-you-go tier is $0 + usage and includes 1M gateway requests and 1M tracing spans per month, 14-day data retention, one seat and a 30 req/min rate limit. Growth is $250/month with a $50 one-time opening credit, 50M gateway requests and tracing spans per month, unlimited seats and a 250 req/min limit. The catalog lists 60 models from OpenAI, Anthropic, Google and open-source labs billed per token, from Schematron V2 Turbo at $0.03/$0.15 to Claude Opus 5 and GPT-6 Astra at $5.00-$10.00 input and $25.00-$50.00 output per 1M tokens.

No free dollar credit: the $0 pay-as-you-go tier includes 1M gateway requests and 1M tracing spans per month, while the $50 one-time opening credit is listed only on the $250/month Growth plan (checked 2026-09-16).

Kilo Code is an open-source (MIT-licensed) agentic coding assistant that runs in VS Code, JetBrains, a CLI, and cloud agents, now branded at kilo.ai after kilocode.ai redirects there. The platform itself is free for individuals: the pricing page lists the Individual plan at $0 with "Usage is billed separately", Teams at $15/user/month and Enterprise as custom, with a 14-day Enterprise trial. Inference is deliberately provider-agnostic - you can use free models, local models via Ollama or LM Studio, or bring your own Anthropic/OpenAI/Google/Azure/AWS keys at $0/mo with "No hosted credit required" - while hosted inference is either pay-as-you-go through Kilo Gateway or a Kilo Pass subscription starting at $19/mo with up to 50% bonus credits.

No free tier stated on official pages (checked 2026-09-16): Kilo publishes a $0 individual plan and a $0/mo free/BYOK/local inference path, but no dollar credit grant; Kilo Pass bonus credits are tied to a paid subscription from $19/mo.
