概览

AI 生成的概览

AgisHub 的远程 MCP 服务器为助手提供 34 个按次付费工具，涵盖持久语义记忆、AI 推理、网页抓取和时间工具。

可以做什么: 在持久记忆命名空间中存储文本并按语义检索，用于 RAG 召回，并提供嵌入和分类。运行聊天、摘要、实体抽取和图像生成等 AI 任务，无需外部 API 密钥。读取、抓取、爬取、映射、截图并驱动无头浏览器访问公开网页，支持按提示或 JSON Schema 做结构化抽取。转换时区、日期、单位和货币，查询节假日并寻找会议时段。生成二维码、缩短网址、发送并跟踪 webhook、生成 PDF 和音频，以及查询加密货币价格。
适用场景: 适合希望用一个端点获得多种通用能力的助手：智能体长期记忆、快速调用 LLM 或嵌入、网页内容抽取，以及时区和单位换算。免费 MCP 层适合探索和原型验证，付费 HTTP 调用适合生产规模。
运行要求: 远程 streamable HTTP 端点；未声明注册、API 密钥或环境变量。MCP 层据称免费。通过 HTTP 路由按次付费需要支持 x402 的客户端，并持有 Base 主网 USDC 的钱包；gas 由 facilitator 承担。

安装前请注意

付费 HTTP 调用使用 Base 主网真实 USDC 且不可撤销，应为专用钱包充值小额余额作为支出上限。工具会写入持久记忆、缩短网址、向任意 URL 发送 webhook 并抓取公开页面；抓取无法访问私有或内部主机。发送给服务的内容会离开本机。

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.

Tool	What it does	Endpoint	Cost
`ai.chat`	Ask 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.classify`	Classify a text into exactly one of the candidate labels you provide (e.g. sentiment, topic, intent).	`/v1/classify`	$0.02
`ai.embed`	Turn text into a numeric embedding vector for semantic search, RAG and similarity. Multilingual.	`/v1/embed`	$0.01
`ai.extract`	Extract named entities from text — people, organizations, locations, dates and miscellaneous — returned as structured JSON.	`/v1/extract`	$0.02
`ai.summarize`	Summarize 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.

Tool	What it does	Endpoint	Cost
`web.browser`	Drive 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.crawl`	Crawl 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.extract`	Fetch 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_structured`	AI-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.links`	Return 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.map`	Discover 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.scrape`	Extract 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.screenshot`	Capture 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.snapshot`	Capture 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.

Tool	What it does	Endpoint	Cost
`data.convert_units`	Convert 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_convert`	Convert 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.calculate`	Timezone-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.convert`	Convert 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.holiday`	Check 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_slots`	Find 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.now`	Get 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.offset`	Get 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.timezones`	List 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

`audio.speak`	Convert text into spoken audio (returned base64-encoded MP3), in several languages.	`/v1/audio-speak`	$0.05
`audio.transcribe`	Transcribe an audio file (given by public URL) to text. Handles mp3, wav, m4a, ogg and more.	`/v1/audio-transcribe`	$0.05
`document.pdf`	Render a public URL or a raw HTML string into a PDF document, returned base64-encoded. Backed by a headless browser. Use for invoices, reports, receipts and any HTML-to-PDF need.	`/v1/pdf`	$0.05
`image.generate`	Generate an image from a text prompt (returned base64-encoded PNG).	`/v1/generate-image`	$0.10

🔧 Developer Tools

QR codes, short links and guaranteed webhook delivery.

`url.shorten`	Shorten 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.send`	Deliver 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.status`	Check the delivery status of a webhook job (queued / retrying / delivered / failed) by its job_id.	`/v1/webhook-status`	$0.01

Quick start

Use the free MCP tools (Claude Code example):

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}'

# 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:

Tier	What	Examples
$0.01	Lookups, conversions, memory	`time.now`, `data.currency_convert`, `memory.search`
$0.02	LLM inference, guaranteed delivery	`ai.chat`, `ai.classify`, `webhook.send`
$0.03	Browser, one page	`web.scrape`, `web.extract`, `web.screenshot`
$0.05	Heavy rendering, media	`web.snapshot`, `document.pdf`, `audio.transcribe`
$0.10	Orchestration, generation	`web.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.
