Why AgisHub

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 — 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.

Free MCP tier to discover and prototype; pay‑per‑call x402 HTTP tier for production, priced per request in USDC.

Two doors, one platform

• MCP (free) — remote Model Context Protocol server. Point Claude / Cursor / any MCP client at the URL and the tools appear.
• HTTP x402 (paid) — POST /v1/<tool>; unpaid requests get a 402 challenge, the client signs a USDC payment (EIP‑3009 on Base) and retries. USDC contract 0x8335…2913.

Tools

24 tools across 13 services. Prices are per call in USDC on Base. Tools marked MCP · HTTP are free via MCP and pay‑per‑call via HTTP x402; tools marked HTTP are paid‑only (they touch metered infrastructure, so they run exclusively on the x402 endpoint).

Quick start

Use the free MCP tools (Claude Code example):

claude mcp add --transport http timezone https://api.agishub.com/mcp

Pay per call over HTTP x402 (any x402 client / wallet):

# Unpaid → 402 challenge; an x402-aware client signs & retries automatically.
curl -X POST https://api.agishub.com/v1/web-scraper \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com","render":true}'

Your agent's wallet only needs USDC on Base — the facilitator covers gas.

For agents & LLMs

• Payments are real USDC on Base mainnet and irreversible. Fund a dedicated agent wallet with a small balance; that balance is your spending cap.
• The free MCP tier never charges. Only the /v1/* (x402 HTTP) routes take payment.
• extract fetches arbitrary public URLs; it will not reach private/internal hosts.

Pricing

Per‑call, in USDC on Base — no subscription. Roughly: $1 ≈ 1,000 timezone calls, ≈ 250 web extractions, or 50 full meeting‑slot searches. Settlement fees on Base are a fraction of a cent and paid by the facilitator.
