## What it does

Monitor stablecoin supply across all major chains. Rising supply = potential buying power entering the market. Falling supply = possible selling pressure. A key leading indicator used by professional traders.

## How to buy

```text
PAID ($0.4/call): call_service({ id: "svc_107778c2-ec37-40a4-a226-d3de024be4cf", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_107778c2-ec37-40a4-a226-d3de024be4cf", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
