Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

appstore

appstore_apps

Paid ($0.003). Apps — App Store. Live data as JSON. Pay with x402 or an Authorization: Bearer bby_live_... credits key.

balance

check_balance

Free. Show the remaining credit balance for the API key sent in this connection's Authorization header. Call this before a long run of paid requests.

data

fetch_data

Paid. Fetch live data from any App Store endpoint. Pass the endpoint path plus its parameters (path and query parameters together in `params`). Priced per call in USDC on Base, Polygon, Arbitrum, Monad or Solana: pay with x402, or send an Authorization: Bearer bby_live_... header to spend prepaid credits. Call describe_endpoint first if unsure about parameters.

describe

describe_endpoint

Free. Show the full call signature for one endpoint: required and optional parameters, allowed values, price, and response shape.

endpoints

search_endpoints

Free. Search fetcher.sh's App Store endpoints by keyword. Returns paths, descriptions and per-call prices. Start here.

topup

topup_credits

Paid (the amount you choose, minimum $1). Buy prepaid credits with x402 so later calls skip the per-call payment round trip. With an Authorization: Bearer bby_live_... header on this connection it recharges that key. Without one, the paying wallet becomes the account and a new API key is minted and returned once — store it as a secret, it cannot be recovered.
