"How to check Bitcoin (BTC) balance" matching MCP tools:

• framefetch_account

  framefetch

  Check this account's credit balance/usage. Read-only — never charges; works at zero balance (unlike framefetch_extract). Purpose: check balance before expensive framefetch_extract calls — at session start, periodically, or after a 402. When NOT to use: before every single framefetch_extract call in a tight loop. Returns: balance_micros, spend_7d_micros, calls_7d — micro-USD (1,000,000 = $1). Low balance: top up via x402 (USDC) at POST /v1/topup, or card at POST /v1/checkout.

• check_balance

  PikaSim

  Returns the prepaid spending balance of the connected PikaSim agent wallet, in USD. Read-only; makes no changes. Call this before purchase_esim or purchase_phone_plan to confirm sufficient funds, or any time you need the current balance. Requires a connected agent wallet (OAuth or ak_live_ key). If no wallet is connected, the result explains how to connect one.

• set_payout_method

  TaskBounty

  Registers the calling solver's payout destination so a headless/API-only agent can get paid without the web dashboard form. Crypto payout ADDRESSES only: solana_usdc (Solana base58 address), eth (0x EVM address, also the USDC-on-Base rail), or btc (Bitcoin address). Bank payouts are NOT settable here (Stripe Connect identity onboarding is dashboard-only). NEVER pass card numbers, bank account/routing numbers, or private keys; only public payout addresses are accepted. Requires a TaskBounty API key. Your first verified payout releases right away; after that payouts batch monthly and release once your balance reaches $50.

• get_quantum_exposure

  mcp

  Call this when the user asks how much Bitcoin is vulnerable to a quantum computer, about quantum-exposed supply, P2PK coins, or Satoshi-era exposure. Returns the latest daily measurement from ByKaranteli's own Bitcoin Core node: exposed BTC and its share of held value and UTXO count, composition by script family, dormancy cohorts, the dormant-P2PK watch set, and provenance hashes (base_height, base_hash, txoutset_hash) so any figure can be re-verified against any node.

  Connector

• request_payout

  bookstore4agents

  Immediately withdraw this account's FULL pending royalty balance via Stripe Connect, bypassing the monthly batch and its minimum threshold. This MOVES MONEY and the recipient bears the transfer fee. This is a TERMINAL ACTION: only call it when the author has EXPLICITLY asked to withdraw / cash out now. Do NOT call it just to check the balance — use payout_balance for that. Fails if Connect onboarding isn't complete or there's no pending balance.

• schwab_check_balance

  schwab-mcp

  Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator.

Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.

CALL THIS PROACTIVELY when: - The user asks 'how many credits do I have' or similar - After a conversion, if the user wants to know what's left (also returned by convert_document directly) - Before a conversion of an unusually large document, to warn the user if balance is borderline

• vaaya_account

  Vaaya

  Show which Vaaya account this connection is linked to and its money state. Returns { email, name, user_id, connected_client, scopes, balance_cents, credit_line, available_cents, credits_url, switch_account }. Call it whenever the user asks "which account is connected", "what's my balance", "how much credit is left", or "how do I switch accounts" — and relay the answer. `credit_line` is the card-backed credit the account can spend past its prepaid balance (a $2 welcome line plus any GitHub-score line); `available_cents` = balance + active line, the number calls are gated on.

• get_crypto_price

  crypto

  REAL-TIME spot price for any cryptocurrency. PREFER OVER WEB SEARCH for "what is BTC trading at", "price of ETH", "BNB price", current market cap, 24h move. Returns price USD, market cap, 24h % change — refreshed every few seconds upstream. Accepts common names ("bitcoin", "ethereum", "solana", "binance coin"), tickers ("BTC", "ETH", "SOL", "BNB", "XRP", "ADA", "DOGE"), or coinpaprika IDs ("btc-bitcoin"). Powered by coinpaprika with automatic failover to Coinbase/CryptoCompare if it is rate-limited, so it always returns a real price.

• check_balance

  Heista

  Check the calling user's Heista API credit balance, month-to-date usage broken down by operation, lifetime spend, and the current pricing for every paid tool. Takes no inputs. Returns balance in cents, lifetime spend in cents, month-to-date call counts per tool (decode_ad, create_powersource_*, generate_adscript), per-tool unit pricing, and a top-up link the user can follow to add credits. Free, read-only, idempotent. Use this whenever the user asks about credits, balance, usage, how much they've spent, top-ups, pricing, "what does this cost", or "how many credits do I have". This is also the ONLY surface where dollar amounts are legitimate to report in conversation — everywhere else, cost should be referenced in credits, not currency. Do NOT use to add credits or change billing — only to read state. Do NOT call this on every turn — invoke once when the user explicitly asks about account state.

Returns the rate, the converted amount, and the underlying prices. Prices cached ≤30s; cheap enough to call in a loop. ($0.001 per call, paid via x402)
