LLM Pricing API: Get AI Model Costs as JSON
Need to access LLM pricing data programmatically? Whether you're building a cost dashboard, a CI/CD pipeline that checks for price changes, or a model selection tool — you need reliable, up-to-date pricing data in a machine-readable format.
That's why we built the APIpulse LLM Pricing API — a free, no-auth JSON endpoint that returns current pricing for 42 AI models across 10 providers.
Quick Start
Get all models with a single GET request:
curl "https://getapipulse.com/api/pricing"
Response includes 42 models with input/output costs, context windows, and provider metadata:
{
"models": [
{
"id": "openai-gpt55",
"name": "GPT-5.5",
"provider": "OpenAI",
"tier": "Premium",
"input": 5.00,
"output": 30.00,
"context": "1M"
},
...
],
"meta": {
"count": 34,
"providers": ["OpenAI", "Anthropic", "Google", ...],
"lastUpdated": "2026-05-29"
}
}
Filter by Provider
Narrow results to a specific provider:
# Get all OpenAI models
curl "https://getapipulse.com/api/pricing?provider=openai"
# Get all Anthropic models
curl "https://getapipulse.com/api/pricing?provider=anthropic"
# Get all budget-tier models
curl "https://getapipulse.com/api/pricing?tier=budget"
Get a Single Model
Fetch pricing for a specific model by ID:
curl "https://getapipulse.com/api/pricing?model=openai-gpt4o-mini"
Use It in JavaScript
// Find the cheapest model for your workload
const res = await fetch('https://getapipulse.com/api/pricing?tier=budget');
const { models } = await res.json();
const inputTokens = 2000, outputTokens = 500;
const monthlyRequests = 30000;
const costs = models.map(m => ({
name: m.name,
monthlyCost: (inputTokens * monthlyRequests / 1e6) * m.input
+ (outputTokens * monthlyRequests / 1e6) * m.output
})).sort((a, b) => a.monthlyCost - b.monthlyCost);
console.log(`Cheapest: ${costs[0].name} at $${costs[0].monthlyCost.toFixed(2)}/mo`);
Use It in Python
import requests
# Get all models and find the cheapest for chatbot workloads
r = requests.get("https://getapipulse.com/api/pricing")
models = r.json()["models"]
for m in sorted(models, key=lambda x: x["input"]):
print(f"{m['name']:25s} ${m['input']:.2f}/${m['output']:.2f} per 1M tokens")
