Tool detail
BlockRun.AI
Proxies an Anthropic-compatible Messages API call (model, messages, max_tokens) to a chosen LLM and returns the completion, billed per token in USDC on Base.
Categories: LLM inference
Use when
- call an Anthropic-style Messages API against a chosen LLM
- get a chat completion with tool-use/streaming support via x402
- run a second-opinion LLM call from an agent without a separate API key
Not for
- not free - billed per token even though the bazaar lists one flat request price
- not image, video or speech - separate BlockRun endpoints handle those
Inputs
POST JSON body: { model: string, max_tokens: integer, messages: array } (required); optional system, temperature, tools[], stream
Inputs undocumented: array without items
