One Key for GPT, Claude, Gemini and 300+ Models — OpenAI-Compatible API at tryallapi.com
What is TryAllAPI?
If you ship LLM features for a living, you already know the pain: one Key for OpenAI, another for Claude, another for Gemini, plus scattered SDKs, billing dashboards, and region headaches. TryAllAPI (also branded MomoAPI on-site) is a multi-model AI API gateway built for that exact mess.
You get one OpenAI-compatible base URL, one API Key, and access to GPT, Claude, Gemini, and 300+ other models—including DeepSeek, Qwen, Kimi, Grok, GLM, MiniMax, and more, with image/video-capable models in the catalog. Point your existing OpenAI SDK at TryAllAPI, change the model string when you want a different brain, and keep shipping.

TryAllAPI is a third-party aggregator. It is not affiliated with OpenAI, Anthropic, or Google. Model names, availability, and prices change—always trust the live console and pricing page.
Why an OpenAI-compatible gateway helps
Most of the tooling ecosystem already speaks OpenAI’s HTTP shape: chat/completions, Authorization: Bearer …, JSON message arrays. That means:
1. Less glue code. LangChain, LiteLLM, Cursor-style custom providers, WorkBuddy custom models, and countless scripts already know how to talk to an OpenAI-compatible endpoint.
2. One Key to rule the catalog. Instead of managing N vendor keys and N billing accounts, you top up a USD balance once and route traffic by model name.
3. Easy A/B. Swap gpt-… for claude-… or gemini-… without rewriting your client—only the model id changes.
If your app already works with the official OpenAI SDK, switching is usually a one-line base_url (or baseURL) change.
How to switch base_url (keep your SDK)
1. Sign up and create a Key
1. Register at tryallapi.com.
2. Top up a small USD balance (from $1).
3. In the console, create an API token and store it securely (env var / secret manager—never commit keys).
2. Point the OpenAI SDK at TryAllAPI
Python
from openai import OpenAI
import os
client = OpenAI(
api_key=os.environ["TRYALLAPI_API_KEY"],
base_url="https://tryallapi.com/v1",
)
resp = client.chat.completions.create(
model="gemini-3.8-flash", # copy exact id from the model plaza
messages=[{"role": "user", "content": "Summarize OpenAI-compatible routing in one sentence."}],
)
print(resp.choices[0].message.content)
Node.js
import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.TRYALLAPI_API_KEY,
baseURL: "https://tryallapi.com/v1",
});
const resp = await client.chat.completions.create({
model: "gpt-6-sol", // example — use a live name from the console
messages: [{ role: "user", content: "Say hello from TryAllAPI." }],
});
console.log(resp.choices[0].message.content);
cURL
curl https://tryallapi.com/v1/chat/completions \
-H "Authorization: Bearer $TRYALLAPI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "claude-sonnet-5-5",
"messages": [{"role": "user", "content": "Ping"}]
}'
3. Model names must match the plaza
Copy model ids exactly from the TryAllAPI model plaza / console (case and hyphens matter). Docs at docs.tryallapi.com walk through common models with call examples and troubleshooting.
Some clients want the full chat completions URL: https://tryallapi.com/v1/chat/completions. The OpenAI SDK usually only needs the /v1 base.
Pricing: pay-as-you-go USD from $1
Billing is prepaid, pay-as-you-go:
- Top up from about $1 (WeChat, Alipay, and cards are commonly supported on-site).
- Usage is deducted from your USD balance.
- Effective cost follows the platform rule: roughly official list price × group multiplier (exact math and multipliers are shown in the console).
- Larger top-ups may include discounts—check the top-up UI.
Always verify live numbers on tryallapi.com—rates move as upstream vendors change list prices.
Practical tip: keep a cheap, fast model as your default for drafting and batch jobs, and route hard coding or long-reasoning tasks to a stronger id only when quality matters. Same Key, different model string.
Who it’s for
TryAllAPI fits developers and small teams who:
- Already use the OpenAI SDK (or OpenAI-compatible proxies) and want Claude / Gemini / DeepSeek without rewriting clients.
- Need one balance instead of juggling multiple overseas cards and vendor dashboards.
- Build agents, chat UIs, RAG pipelines, or IDE plugins that should swap models often.
- Want a low-risk way to benchmark models on real traffic before locking into a single vendor.
It is not a replacement for vendor-specific advanced APIs when you need every proprietary feature of a single cloud.
Quick checklist before you go to prod
1. Env-only secrets — rotate any Key that ever appeared in a screenshot or chat.
2. Exact model ids — copy from the plaza; typos produce model errors.
3. Balance alerts — insufficient balance rejects requests; keep a small buffer.
4. Context limits — set max tokens to what the chosen model actually supports.
5. Disclaimer — third-party routing; not affiliated with OpenAI / Anthropic / Google; SLA and model list can change.
Get started
1. Open tryallapi.com and create an account.
2. Top up from $1 and create an API Key.
3. Set base_url / baseURL to https://tryallapi.com/v1.
4. Call /chat/completions with a model id from the plaza.
5. Read guides on docs.tryallapi.com.
One Key. OpenAI-compatible. GPT, Claude, Gemini, and 300+ models. Pay-as-you-go USD.
