Petty docs

Overview

A prefunded petty-cash vault for pay-per-request agents, with hard caps and receipts you can reconcile..

Spending limits are enforced before payment, at the vault, not just reported afterward. The owner gets accounting-grade receipts, which raw payment rails do not give them.

Built for developers and teams running research, scraping or tool-using agents that buy data and compute per request, and the people who answer for their bills..

Getting started

1. Paste an address. Any SPL token mint.
2. Read the report. Each check explained.
3. Share it. Link or image.

Vault creation on Solana with a single signed deposit and withdraw back to the owner at any time

Paste an address and get a plain report in about a second. Each line says what was checked and what it means.

Policy editor: caps per agent, per service domain and per day, plus an allowlist of payees

Line several tokens up side by side and sort by what matters to you.

Drop-in fetch middleware (npm package) that handles 402 responses, checks policy and pays

Every report has a link and an image you can post, so others see the same facts you saw.
