Free LLM price API

LLM prices for your app, site or README.

The prices behind Alye's model price list for 1,271 models, as JSON, a price table or a badge. Free, no key or sign-up, updated Oct 28, 2026. All we ask is a visible link back.

Embed a price table or badge

Pick models, then copy the snippet. Prices stay current on their own: the table and badges are served from www.alye.ai, so you never update them by hand.

The JSON API

GET https://www.alye.ai/api/prices returns every current model. Browsers can call it from any site (CORS is open), and answers are cached for an hour.

bash

curl "https://www.alye.ai/api/prices?model=openai/gpt-5,anthropic/claude-sonnet-5-5"

import requests

prices = requests.get("https://www.alye.ai/api/prices", params={"provider": "openai"}, timeout=10).json()
for m in prices["models"]:
    print(m["name"], m["input"], m["output"])   # US dollars per million tokens

const res = await fetch("https://www.alye.ai/api/prices?model=gpt-5");
const { models, attribution } = await res.json();
console.log(models[0].input, models[0].output);   // US dollars per million tokens

Query parameters

model: One or more models, comma-separated: openai/gpt-5 or just gpt-5 (the model maker's own price is picked first).
provider: Only one provider: openai, anthropic, aws-bedrock, azure-openai, vertex-ai, google-gemini, ...
mode: chat or embedding.

Fields

contextWindow: Maximum tokens per request, when known.

Terms of use

Free for any use, including commercial products.
Show a visible link to www.alye.ai/models wherever you show the prices, for example “Prices by Alye”. The embed and badge snippets include it.
Cache answers on your side; prices change at most a few times a day. Very heavy traffic may be rate limited.
Prices are list prices and may lag a provider's announcement by up to a day. There is no uptime guarantee; check the provider before committing to a budget. Questions or higher volumes: info@alye.ai.

Want the cost of your calls, not just list prices? Alye records each call and prices it for where it ran. See how LLM cost tracking works.
