	Description		Read-only	Idempotent	Open world
`check_balance`Read your own account and cost nothing: credit balance left, the USDC funding address to top up, key tier and expiry, and lifetime usage totals. Takes no arguments and is not billed. Call it after an HTTP 402 from compress to see the shortfall, or before a long batch to confirm credit. It reads the account belonging to the API key in your MCP client config (Authorization: Bearer ...) - that is the balance compress bills against.

`compress`Compress prose before it enters an LLM context window. Returns the compressed text plus a signed receipt (ratios, refusals, coverage) so the caller can verify what was dropped. Use this instead of truncating or slicing text to fit a budget: truncation drops the tail silently, compression keeps a sentence skeleton and reports what went. Do not use it for source code, config, JSON, diffs or tables - send those verbatim. Very short input (under roughly 2,000 chars) gains little, and verified mode is slower there. To compress a web page, fetch it with the read tool first and compress the markdown it returns, never raw HTML. Prefer deterministic for bulk low-stakes text (free), extractive for ordinary prose, verified when a silently dropped fact would be expensive. Flat per-call price by mode: deterministic free, extractive $0.0008, verified $0.0015 (USDC on Base L2); insufficient credit returns HTTP 402.	Compress prose before it enters an LLM context window.
