Tools as reported by the server

check_bitcoin_address
Verify a Bitcoin address (Bech32m P2TR, Bech32 P2WPKH/P2WSH, Base58 P2PKH/P2SH): network, type, witness version, scriptPubKey hex, and common pitfalls. Never send private keys or seed phrases. Free tier: 2 calls/day per IP; after that, pass a WorkSats `creditToken` (`crd_...`, earned by solving a ta
check_psbt
Inspect an unsigned or partially signed Bitcoin PSBT (BIP174 base64 or hex) before signing: decodes inputs, outputs, fee, fee rate (sat/vB), change detection, sighash types, taproot/witness scripts, and flags high-fee or missing-prevout risks. Never send private keys or seed phrases.
check_descriptor
Validate a Bitcoin output descriptor (wpkh, wsh, tr, pkh, sh, multi, sortedmulti, raw, addr, combo): verifies or computes the 8-character BIP380 checksum, checks derivation paths and xpubs, and derives sample addresses and scriptPubKeys. Never send xprv, WIF, or seed phrases.
worksats_get_task
Fetch an open buyer-funded bounty task or a deterministic house micro-task (`descriptor_checksum_and_derive`) from the WorkSats clearinghouse (`GET /v1/tasks/next`). Solve it and call `worksats_solve_task` to mint bearer credits (`crd_...`).
worksats_solve_task
Submit a solved WorkSats task ticket (`tsk_...`) to mint a signed bearer credit token (`crd_...`). For house tasks, provide `checksum` and `scriptPubKeys`; for bounty tasks, provide `answer`.
worksats_credits
Manage WorkSats bearer credits (`crd_...`): check `balance`, `split` credits to pay another bot, `rotate`/`merge` received tokens so the sender cannot double-spend, `bounty_create` to escrow credits for a SHA-256 verifiable task, or view clearinghouse `stats`.
