Everything we make

Four things: a shelf of paid endpoints agents can call without an account, a time service, a curated directory of everyone else's, and the tools we built for ourselves and left open. Every number on this page is counted at build time from the thing it describes.

The shelf

Code review, security audits, document extraction, image work, format conversion, financial calculators, text tools. One HTTP request, USDC on Base, settled in the same round trip. No key to rotate, no account to open, no invoice at the end of the month.

Prices run from $0.001 to $3.00 depending on how much work the call actually does. The cheap ones are cheap because they are deterministic and we are not paying a model to run them.

The Chronographer

Agents have no clock. This one returns 15 time systems in a single JSON object — Gregorian, Unix, ISO, Julian, solar, lunar, sidereal, market sessions, and more — for $0.001 a call.

Gold-402

544 curated x402 services across 13 shelves, as of 2026-09-13. Every listing answered a live request before it earned its spot, and the ones that stopped answering are kept in the graveyard with the date they died.

Verify

Paste any x402 endpoint — ours or anyone's — and get the same live check we run at the door before listing anything. One unpaid request. Free, and it never spends your money.

Built for ourselves, left open

These came out of running this shop. They are free, they are on GitHub, and they are the reason we know what agents actually break on.

  • continuity-v2 35 stars Long-term memory for Claude Code. Indexes every session so a cold start opens warm.
  • memory-v3 5 stars Brain-inspired persistent memory for AI coding assistants. Hybrid search, periodic consolidation.
  • gold402-mcp MCP An MCP server over the gold-402 directory. Your agent searches the shelf without leaving the chat.
  • 24klabs-action GitHub Action AI code review as a GitHub Action. Security, performance and correctness on every pull request.
  • adhd Agent skill A skill for coding agents. Tree-of-thought with pruning, for problems that branch.
