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 https://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 https://docs.tryallapi.com/ walk through common models with call examples and troubleshooting.

Some clients (e.g. WorkBuddy custom models) 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.

There is no need to buy a fixed monthly seat just to try a new model. Spin up a Key, put $1–$10 on the account, and measure real token spend on your workload. Always verify live numbers on https://tryallapi.com/pricing—rates move as upstream vendors change list prices.

Practical tip: keep a cheap, fast model (e.g. a Flash / Sol-class id from the plaza) as your default for drafting and batch jobs, and route hard coding or long-reasoning tasks to a stronger Claude / flagship GPT 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.
• Integrate tools like WorkBuddy custom models or other OpenAI-compatible “provider” slots—see the GitHub guide above.

It is not a replacement for vendor-specific advanced APIs when you need every proprietary feature of a single cloud. Use it when protocol compatibility and catalog breadth matter more than exclusive vendor tooling.

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 404-style 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 https://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 call guides and prices on https://docs.tryallapi.com/.

One Key. OpenAI-compatible. GPT, Claude, Gemini, and 300+ models. Pay-as-you-go USD.
