概覽

AI 產生的概覽

AgisHub 的遠端 MCP 伺服器整合 34 個實用工具——Webhook、網頁擷取、時間、AI、媒體與記憶——透過 MCP 免費使用，HTTP 按次付費。

可以做什麼
  • 送出含重試機制的 Webhook 並查詢投遞狀態
  • 擷取、爬取、對應、截圖並以無頭瀏覽器操作公開網頁，支援結構化擷取
  • 時區轉換、日期運算、假日與會議時段，以及單位與貨幣換算
  • 呼叫大型語言模型對話、分類、向量嵌入、實體擷取與摘要
  • 產生 QR 碼、短連結、圖片、語音、轉錄文字與 PDF
  • 儲存並以語意搜尋持久化記憶命名空間
適用情境
當助理需要一批零散實用能力——可靠的 Webhook 投遞、網頁讀取與截圖、時區計算，或快速的模型與媒體呼叫——又不想分別註冊各家 API、管理金鑰時，值得加入。
執行需求
遠端 MCP 端點，使用 streamable HTTP；未宣告需要帳號、API 金鑰或環境變數。免費 MCP 層只需網路存取。付費 HTTP 路由需要支援 x402 的用戶端，以及在 Base 上持有 USDC 的錢包。
安裝前請注意
付費 HTTP 路由按次收取真實且不可撤銷的 Base 鏈上 USDC，建議使用餘額較少的專用錢包作為支出上限。Webhook 傳送與記憶儲存會把資料寫入第三方；擷取工具會存取任意公開網址。說明稱免費 MCP 層不會收費。

安裝

AgisHub

Pay-per-call tools for AI agents — no signup, no API keys, just USDC.

▶ Try any tool live in your browser — no install

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.

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

34 tools across 7 categories. Prices are per call in USDC on Base, from $0.01. Every tool is free to try over MCP; the HTTP endpoint is the one that charges.

🤖 AI & Inference

Language models, embeddings and classification — no external API key.

ToolWhat it doesEndpointCost
ai.chatAsk a general-purpose LLM a question or give it an instruction, with an optional system prompt. No external API key required./v1/chat$0.02
ai.classifyClassify a text into exactly one of the candidate labels you provide (e.g. sentiment, topic, intent)./v1/classify$0.02
ai.embedTurn text into a numeric embedding vector for semantic search, RAG and similarity. Multilingual./v1/embed$0.01
ai.extractExtract named entities from text — people, organizations, locations, dates and miscellaneous — returned as structured JSON./v1/extract$0.02
ai.summarizeSummarize a block of text into a short abstract, with an optional target length. No external API key required./v1/summarize$0.02

🕸️ Search & Web

Read, scrape, crawl and map any public page.

ToolWhat it doesEndpointCost
web.browserDrive a headless browser: open a URL and run an ordered list of steps — click, type, press keys, wait, extract text and screenshot. For flows the plain scraper can't reach (logins, forms, multi-step pages)./v1/browser-automate$0.10
web.crawlCrawl multiple pages of a site, respecting link depth and domain limits. Returns async job_id; results include markdown or HTML per page. Use it to fetch and process many pages of content at once./v1/crawl$0.10
web.extractFetch any public web page and return its main content as clean, token-efficient Markdown (title, description, headings, links, lists). Set render:true to execute JavaScript first for single-page apps or JS-heavy pages that would otherwise come back empty. Built for RAG and for agents that need to read the contents of a URL./v1/web-scraper$0.03
web.extract_structuredAI-powered structured extraction: give a URL plus a natural-language prompt and/or a JSON Schema, and get back clean structured JSON (e.g. product name, price, rating). Renders the page in a headless browser first, so it works on SPAs./v1/extract-structured$0.05
web.linksReturn every hyperlink on a JavaScript-rendered page as a list of absolute URLs, with options to keep only visible links or only same-site links. Backed by a headless browser. Use it to map a site or seed a crawler./v1/links$0.03
web.mapDiscover all URLs reachable from a domain within a link depth limit. Returns a flat list of absolute URLs, respects robots.txt crawl delays. Use it to map a site's structure before crawling./v1/crawl-map$0.05
web.scrapeExtract specific elements from a JavaScript-rendered page by CSS selector. Give a list of selectors (e.g. 'h1', '.price', 'a.product') and get back the text and attributes of every match. Backed by a headless browser, so it works on SPAs and JS-heavy pages./v1/scrape$0.03
web.screenshotCapture a PNG screenshot of any public URL — full page or just the viewport, at a chosen size — returned base64-encoded. Backed by a headless browser./v1/screenshot$0.03
web.snapshotCapture several representations of a page in one call — rendered HTML plus a PNG screenshot by default, and optionally Markdown and the accessibility tree. Backed by a headless browser. Saves round-trips when an agent needs both the content and a visual of a page./v1/snapshot$0.05

📊 Data & Analytics

Time, timezones, units and currency.

ToolWhat it doesEndpointCost
data.convert_unitsConvert a value between units of the same category: length, mass, volume, speed, area, digital storage, time, and temperature (Celsius/Fahrenheit/Kelvin)./v1/units-convert$0.01
data.currency_convertConvert an amount between currencies using live daily exchange rates (ISO 4217 codes, e.g. USD, EUR, GBP, JPY). Returns the converted amount and the rate used./v1/currency-convert$0.01
time.calculateTimezone-aware date arithmetic: add or subtract a duration to a datetime (days are calendar-based and DST-safe; hours and minutes are absolute), or compute the difference between two datetimes that may be in different zones./v1/date-calculate$0.01
time.convertConvert a specific date/time from one IANA timezone to another (single or batch). Accepts ISO 8601 or natural language ('next Tuesday 3pm'). Returns the converted datetime with UTC offset, zone abbreviation and DST flag./v1/time-convert$0.01
time.holidayCheck whether a given date is a public holiday in a country (identified by its ISO 3166-1 alpha-2 code), and return the holiday name if so. Backed by an authoritative public-holiday dataset./v1/time-holiday$0.01
time.meeting_slotsFind working-hour time slots that overlap across participants in different timezones for a meeting of a given duration, excluding weekends and (when a country is given per participant) that person's public holidays. Free tier returns at most 1 slot; the paid endpoint returns every matching slot (see 'upgrade' in the response)./v1/meeting-slots$0.10
time.nowGet the current local time in an IANA timezone, including the UTC offset, zone abbreviation and whether DST is in effect. Use whenever you need to know what time it is 'now' somewhere./v1/time-now$0.01
time.offsetGet the exact UTC offset of an IANA timezone at a given instant, DST-aware. Correctly handles fractional offsets such as India +05:30 and Nepal +05:45./v1/time-offset$0.01
time.timezonesList or search valid IANA timezone identifiers by city/region/country, and resolve a city/country name to its timezone(s). Use it to discover the exact identifier to pass to the other tools./v1/timezones$0.01

💱 Market Data

Live crypto prices.

ToolWhat it doesEndpointCost

url.shortenShorten a long URL into a compact api.agishub.com/s/ link that redirects to the original. Codes are stored for a year./v1/shorten$0.01
webhook.sendDeliver a webhook (POST/PUT/PATCH a JSON payload to a URL) with guaranteed, retried delivery. Returns immediately with a job_id; AgisHub keeps retrying in the background until it succeeds./v1/webhook-send$0.02
webhook.statusCheck the delivery status of a webhook job (queued / retrying / delivered / failed) by its job_id./v1/webhook-status$0.01

🧠 Knowledge & Memory

Persistent, semantically searchable memory.

ToolWhat it doesEndpointCost
memory.searchSemantically search a memory collection (namespace) and return the most relevant stored entries. The retrieval half of RAG./v1/memory-search$0.01
memory.storeStore a piece of text in a persistent, searchable memory collection (namespace). Embedded and indexed for later semantic recall./v1/memory-store$0.01

Quick start

Use the free MCP tools (Claude Code example):

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

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

bash
# 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, no signup, no API key. Five tiers, by what a call actually costs to run:

TierWhatExamples
$0.01Lookups, conversions, memorytime.now, data.currency_convert, memory.search
$0.02LLM inference, guaranteed deliveryai.chat, ai.classify, webhook.send
$0.03Browser, one pageweb.scrape, web.extract, web.screenshot
$0.05Heavy rendering, mediaweb.snapshot, document.pdf, audio.transcribe
$0.10Orchestration, generationweb.crawl, web.browser, image.generate

Roughly: $1 ≈ 100 timezone calls, ≈ 33 web extractions, or 10 crawls of up to 100 pages each. Settlement fees on Base are a fraction of a cent and paid by the facilitator.

web.crawl and web.map are capped per call (100 pages, 200 URLs) and priced flat, so a larger site is several calls at the same rate rather than one unbounded charge.
