• 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_...`),…

• 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 phr…

• 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_credits

  Manage WorkSats bearer credits (`crd_...`): check `balance`, `split` credits to pay another bot, `rotate`/`merge` received tokens so the sender cannot double-spend, `mint` credits from L402 or x402 Base USDC, `bounty_create` to escrow credits for a verifiable task (`sha256`, `de…
