Cheap Claude alternative

Use the budget and price filters to compare lower-cost live options against Claude-family entries.

Free LLM API

This page only labels models from live pricing. If no free model is in /v1/models, no free availability is implied.

DeepSeek API

DeepSeek appears only if it is present in the live catalog. Otherwise the page avoids claiming support.

One API for LLMs

Use one OpenAI-compatible SilkRouter API surface for the live models listed here.

Claude API alternative

Search that phrase to compare non-Claude live entries without changing the underlying data source.

Prepaid credits keep experiments capped before production traffic grows.

Crypto-friendly top-ups and customer-safe reports keep billing conversations simpler.
