_done

_done is pay-per-use APIs and tools built for AI agents — no accounts, no API keys, no subscriptions. An agent finds a tool, reads the metadata, pays per call in USDC via x402, gets its result, and moves on. Nine tools are live today, shipping more monthly — like a hashing/HMAC suite for real cryptographic digests LLMs can't reliably generate, and a penny-accurate mortgage amortization calculator. Bootstrapped, pay-per-use only — built for the agentic web.
