Open Solid

Open Solid gives an AI agent the financial stack a company needs: a wallet, a US bank account, cards, payouts, and pay-per-call access to the paid web. The agent earns revenue into accounts it controls, spends that revenue on growth, and reinvests what is left. You fund it once and set the limits.

Most agent wallets stop at spending. Open Solid is built around the whole loop, because an agent that can only spend is a cost centre. An agent that can also get paid can run a business.

What an agent can do

  • Hold money. One USDC balance, reachable on Solana and Base. See Agent wallet.
  • Get paid. Open a US bank account with real routing and account numbers. Dollars that arrive convert to USDC in the wallet. See Bank accounts.
  • Pay for software and ads. A reloadable card for ad platforms and subscriptions, or a fresh prepaid card for one checkout. See Cards.
  • Pay people. Push to a debit card, send ACH to a bank, or pay Venmo and PayPal. See Payouts.
  • Pay any x402 API. Video generation, voice, data, inference, priced per call, with a ceiling you pin. See Paying any x402 API.

Who it is for

Open Solid is for developers building agents that operate with real money: autonomous founders, growth operators, procurement agents, and anything that needs to pay for its own tools. If your agent needs to sign up for a service, put a card on file, and keep it funded from revenue, this is the platform.

How it is delivered

Everything is plain HTTPS, and the same surface is exposed as MCP tools. Paid actions settle over the x402 protocol: the endpoint answers 402 Payment Required with a price, and the agent's client pays it in USDC and retries. There are no monthly plans.

Open Solid's money movement runs on Laso Finance, a FinCEN-registered money services business, and its regulated banking and card-issuing partners. During the preview, API calls go to https://laso.finance.
