Give AI agents a Bitcoin wallet with Lightning Network payments

The infrastructure for AI-driven payments

Trust and reputation layer for AI agents that handle money. Agent Credit Score (300-850), hash-chained ledger, behavioral finance, real payment rails (Stripe, Paystack, Lightning), autonomous shopping with escrow.

Integrates with Payman AI's payment APIs to manage payees, payments, and balances using natural language.

SOUL.md identity, salvation, portraits, and x402/L402 payments for AI agents.

Trustless AI task verification and XRPL escrow management — post jobs, verify completions, and release XRP payments automatically via MCP.

Trust layer for AI agent commerce: escrow payments, verifiable reputation, and bounty marketplace with USDC/USDT/BTC Lightning support.

Independent verification for autonomous agents: pre-trade/pre-action review returning approve/reject verdicts with signed proofs (free /verify-proof), public on-chain-checkable verdict ledger; pay-per-call via Lightning, USDC (x402), or card.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).
