Persistent semantic memory for AI agents: store and recall text by meaning (RAG, Vectorize). x402
Copy the AI prompt to install this server into Claude Code, Cursor, or another agent â or use 1-click editor setup below.

Inspect callable tools, capabilities, and parameters exposed to AI agents by Agent Memory.
now_inCurrent local time in an IANA timezone â UTC offset, abbreviation, DST flag.
convert_timezoneConvert a datetime between two IANA zones. Accepts ISO 8601 or natural language ("next Tuesday 3pm").
convert_batchConvert one instant into many zones at once â ideal for worldâclock views.
tz_offsetExact UTC offset of a zone at a given instant (DSTâaware; handles +05:30, +05:45).
lookup_timezoneResolve a city or country to its IANA timezone(s). "Delhi" â `Asia/Kolkata`.
date_mathAdd/subtract time respecting DST, or diff two datetimes across zones.
Pay-per-call tools for AI agents â no signup, no API keys, just USDC.
Live data & utilities over x402 micropayments on Base. Your agent pays a few tenths of a cent per call from its own wallet; no accounts, no monthly plans.
Traditional APIs make an agent stop and ask a human: sign up, create an account, copy an
API key, add a credit card, read the docs. AgisHub tools are callable the moment an agent
has a funded wallet â the server answers HTTP 402, the agent signs a USDC payment on
Base, and the data flows back. Under a second, no human in the loop.

| Multiple tools, one door | â | one vendor | â |
Free MCP tier to discover and prototype; payâperâcall x402 HTTP tier for production, priced per request in USDC.
POST /v1/<tool>; unpaid requests get a 402 challenge, the client
signs a USDC payment (EIPâ3009 on Base) and retries. USDC contract 0x8335âŚ2913.24 tools across 13 services. Prices are per call in USDC on Base. Tools marked MCP ¡ HTTP are free via MCP and payâperâcall via HTTP x402; tools marked HTTP are paidâonly (they touch metered infrastructure, so they run exclusively on the x402 endpoint).

Pay per call over HTTP x402 (any x402 client / wallet):
Your agent's wallet only needs USDC on Base â the facilitator covers gas.
/v1/* (x402 HTTP) routes take payment.extract fetches arbitrary public URLs; it will not reach private/internal hosts.Perâcall, in USDC on Base â no subscription. Roughly: $1 â 1,000 timezone calls, â 250 web extractions, or 50 full meetingâslot searches. Settlement fees on Base are a fraction of a cent and paid by the facilitator.
