AgisHub is a freemium MCP + HTTP x402 server that gives AI agents live data, web, AI, memory, webhook, finance, and utility tools with no signup or API keys—paid per call in USDC on Base.
Timezone & scheduling: current time, conversions between IANA zones, batch world-clock conversion, DST-aware offsets, date math, meeting-slot finding across timezones, and public-holiday checks.
Web/content: extract pages as clean markdown (with optional JS rendering), plus paid scraping, structured JSON extraction, snapshots/screenshots, and link harvesting.
AI/NLP: summarize text, classify into labels, extract entities, generate embeddings, chat with an LLM, transcribe audio, and convert text to speech.
Memory/RAG: persistent semantic memory with namespace-based upsert and similarity search.
Webhooks: reliable webhook delivery with background retries and status tracking.
Finance/crypto: live currency conversion and USD crypto spot prices.
Utilities: generate QR codes, convert units, and shorten URLs.
Browser/render (paid-only): render PDFs, take screenshots, generate images, and automate headless-browser flows.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@AgisHub MCP Server Convert 3 PM New York time to London time."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Pay-per-call tools for AI agents — 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 — 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.

Language models, embeddings and classification — no external API key.
Tool | What it does | Endpoint | Cost |
| Ask a general-purpose LLM a question or give it an instruction, with an optional system prompt. No external API key required. |
| $0.02 |
| Classify a text into exactly one of the candidate labels you provide (e.g. sentiment, topic, intent). |
| $0.02 |
| Turn text into a numeric embedding vector for semantic search, RAG and similarity. Multilingual. |
| $0.01 |

Read, scrape, crawl and map any public page.
Tool | What it does | Endpoint | Cost |
| 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). |
| $0.10 |
| 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. |
| $0.10 |
| 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. |
| $0.03 |
| 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. |
| $0.05 |
| 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. |
| $0.03 |
| 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. |
| $0.05 |
| 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. |
| $0.03 |
| 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. |
| $0.03 |
| 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. |
| $0.05 |
Time, timezones, units and currency.
Tool | What it does | Endpoint | Cost |
| Convert a value between units of the same category: length, mass, volume, speed, area, digital storage, time, and temperature (Celsius/Fahrenheit/Kelvin). |
| $0.01 |
| 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. |
| $0.01 |
| 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. |
| $0.01 |
| 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. |
| $0.01 |
| 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. |
| $0.01 |
| 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). |
| $0.10 |
| 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. |
| $0.01 |
| 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. |
| $0.01 |
| 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. |
| $0.01 |
Live crypto prices.
Tool | What it does | Endpoint | Cost |
| Get live USD spot prices for one or more cryptocurrencies by ticker symbol (e.g. BTC, ETH, SOL). |

| Shorten a long URL into a compact api.agishub.com/s/ link that redirects to the original. Codes are stored for a year. |
| $0.01 |
| 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. |
| $0.02 |
| Check the delivery status of a webhook job (queued / retrying / delivered / failed) by its job_id. |
| $0.01 |
Persistent, semantically searchable memory.
Tool | What it does | Endpoint | Cost |
| Semantically search a memory collection (namespace) and return the most relevant stored entries. The retrieval half of RAG. |

Use the free MCP tools (Claude Code example):
claude mcp add --transport http timezone https://api.agishub.com/mcpPay 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.
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.
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 |
|
$0.02 | LLM inference, guaranteed delivery |
|
$0.03 | Browser, one page |
|
$0.05 | Heavy rendering, media |
|
$0.10 | Orchestration, generation |
|
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.

Scored across 25 tools
Most tools are clearly distinct in purpose, but there are several timezone-related tools (now_in, convert_timezone, convert_batch, tz_offset, list_timezones, lookup_timezone) that could be confusing at first glance. The descriptions help, but the overlap in that domain is noticeable. 'extract' and 'extract_entities' are also somewhat close in name but serve different functions.
All names use snake_case, which is good, but there is inconsistency between verb_noun forms (convert_timezone, list_timezones), single-verb forms (extract, summarize, classify), and noun forms (price, status, qr_code). Some prefixes are repeated (convert_*, memory_*), but overall the pattern is not uniform across the set.
With 25 tools, this server is at the upper bound of what feels reasonable. Each tool seems individually useful, but the set is very broad, spanning timezones, text processing, webhooks, URL utilities, crypto, and more. It feels heavy rather than well-scoped, but not excessively so.
Because the server covers many unrelated domains, it's hard to assess completeness. Within each domain, there are gaps (e.g., memory lacks delete/collection management, webhooks lack cancellation). However, for general-purpose utilities, it offers a wide range of functionality, so the overall surface is not severely incomplete.
