OpenRouter
OpenRouter
OpenRouter is a unified interface for LLMs. OpenRouter scouts for the lowest prices and best latencies/throughputs across dozens of providers, and lets you choose how to prioritize them. No need to change your code when switching between models or providers. You can even let users choose and pay for their own. Evals are flawed; instead, compare models by how often they're used for different purposes. Chat with multiple at once in the chatroom. Model usage can be paid by users, developers, or both, and may shift in availability. You can also fetch models, prices, and limits via API. OpenRouter routes requests to the best available providers for your model, given your preferences. By default, requests are load-balanced across the top providers to maximize uptime, but you can customize how this works using the provider object in the request body. Prioritize providers that have not seen significant outages in the last 10 seconds.Starting Price: $2 one-time payment -

OpenGraph
OpenGraph
OpenGraph.io is a developer-focused web API service that fetches and returns structured metadata from any given URL, primarily Open Graph tags such as title, description, image, and other relevant page information, so applications can generate rich link previews, embed contextual content, and automate metadata extraction without building custom scrapers. It works even on pages that lack well-defined Open Graph tags by inferring missing values from the page’s HTML, and offers different endpoint capabilities, including pure Open Graph tag extraction, more extensive content extraction (headers, paragraphs, structured page text), full HTML scraping with JavaScript rendering support, and high-speed screenshot capture for visual previews of web pages. The API returns data in a consistent JSON format tailored for integration into workflows, dashboards, apps, and marketing or content platforms, and developers can call it programmatically using API keys with SDKs or standard HTTP requests.Starting Price: $25 per month -

Otonomo
Otonomo
The Otonomo Platform provides secure data management and gives drivers granular controls over how their personal automotive data is shared. Patented technology performs data blurring for use cases requiring blurred data. Many mobility services can’t operate well without data from multiple automotive manufacturers (OEMs). Yet individual OEMs lack incentives to consolidate each others’ data. As a neutral third party, Otonomo aligns OEMs and the multitude of valuable apps and services that use car data. Third-party apps and services gain easy data access, while OEMs maintain control over which services can access their data. Our platform uses patented technology to cleanse, normalize, and enrich automotive data so that it is immediately usable by our ecosystem partners. We build enriched datasets that incorporate third-party sources and aggregated events and metrics for key use cases to save time and cost in development processes. -
