FAQ
Will the catalog itself ever go behind a paywall?
No. agentalmanac.org/catalog stays free forever. Paid tiers gate the API for programmatic access — agents calling JSON endpoints at volume. Humans browsing the catalog with a browser will never hit a paywall.
When do the paid tiers actually launch?
Target: next 1-2 weeks. Email signups above will get the launch announcement first, with founder pricing locked in.
Why both monthly subscription AND x402?
Different audiences. Humans building products want predictable monthly billing. Autonomous agents want per-call settlement without account management. We offer both because both are valid; you pick whichever matches how you operate.
What does "founder lifetime" actually mean?
First 100 buyers pay $99 once and get the Developer tier (10K requests/mo) for as long as the Agent Almanac exists. No renewal, no surprise price hike, no "we're sunsetting your plan" emails. After the first 100, the tier becomes $19/mo.
What about the MCP server for searching the catalog?
agentalmanac-mcp stays free for the foreseeable future. It's a thin wrapper around the public API, so it inherits whatever tier applies to the underlying call. With no key, you get the free tier (50/day per IP). With a key configured, you get your tier's quota.
