## Tools (as reported by the server, not verified)

- `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\`.
