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 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 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 https://tryallapi.com/pricing—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 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 guides on https://docs.tryallapi.com/.

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