Nothing serious here today
Today is the operative word: we check SwarmIO every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
runs
runs.cancel
Stop a running job.
runs.get
A run's status and metadata. Poll until status is completed/failed/cancelled.
runs.launch
Launch a run: agents search the web, read sources, and write a cited report — real work, done for the caller. BILLED from the caller's credits. Returns the run record; poll runs.get until completed, then runs.report. Modes: research, news, product, trips, trainer, finance, astrology, horoscope (astrology/horoscope take Birth date constraint lines — see https://ioswarm.io/llms.txt).
runs.report
The finished, cited report for a completed run (report_text is markdown).
runs.wait
Block until a run finishes, then return its record — and its report when it completed. Runs take 3–10 minutes; call this instead of polling runs.get in a loop. Returns early with timed_out=true after timeout_secs (default 90, max 240): call it again with the same run_id to keep waiting. Never charged.
billing
billing.balance
The caller's credit balance and plan state.
billing.topup_terms
How to refill credits machine-to-machine: USDC on Base to a published address, verified on-chain. Returns the pay_to address, minimum, and rate. Public — no credentials needed.
fetch
fetch
Read one report by the id search returned: the full markdown text with its citations and evidence header, plus title, url and metadata. Public reports need no key; a caller's own reports need theirs.
market
market.pulse
FREE, no key, no account: live prices for BTC, ETH, SOL, AMZN and NVDA with the session's change, plus today's news — the platform's newest published news digest parsed into stories with source links, and the market wire's latest headlines. Refreshed every minute (prices) and every ten minutes (news). Call this first to see what the swarm's data looks like before spending anything.
modes
modes.list
The launchable modes with a one-line contract for each. Static; never charged, no credentials needed.
news
news.brief
PAID, 5¢ per call over x402 (USDC on Base, no account): today's market-news brief — this platform's newest published news digest synthesized with the live market wire into a cited bullet list, every finding ending with its source URL. No input required; the settle happens over HTTP, where the payment headers live: this tool returns the exact steps. The FREE raw material it is written from is market.pulse on this same server (the digest stories and wire headlines, un-synthesized).
route
route.classify
Classify a freeform request into the right mode (research, news, finance, astrology, …) before spending a run. Never charged.
search
search
Search the swarm's published research: the featured shelf, the operator's daily news / markets / AI digests, and — when a key is presented — the caller's own reports. Every hit is a finished, cited, evidence-graded report. Returns {results:[{id,title,url}]}; pass an id to fetch. No key needed for the public corpus. (The research-connector contract: this is what a ChatGPT or Claude connector calls.)
web
web.search
FREE, no key, no account: LIVE web search, 25 queries a day per caller, up to 5 results each ({results:[{url,title,snippet,published}], quota, report}). This is the open web, not the published corpus — for the platform's finished reports use `search`. Over the daily quota the paid leg is $0.02 per call over x402 (USDC on Base): POST https://ioswarm.io/api/v1/search with the same JSON body and no payment header, read the 402, sign the EIP-3009 authorization, re-send with X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2) — no account is created. The response's `report` field shows the one-call cited research brief (5¢, pay-only) for when raw results are not enough.

SwarmIO — questions
Answers built from our own checks of this server.
What can SwarmIO do?
It exposes 14 tools, read directly from the server on our last check. Among them: billing.balance, billing.topup_terms, fetch, market.pulse, modes.list, news.brief and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is SwarmIO mostly used for?
Its tools cluster around runs and billing. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is SwarmIO working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 380 ms. The bar chart above shows every period we have measured.
How do I connect SwarmIO?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SwarmIO need an API key?
No. SwarmIO completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SwarmIO?
It answers our handshake in 380 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
