A hosted agent harness: deep research as an API. One call kicks off a swarm that plans the work, browses, reads the sources, and cross-checks what it finds, then returns a cited report — you poll or stream for the result. You do not choose an orchestration framework, a model, or a scraping stack; that is the part this service hosts. Modes cover deep research, news briefs, product scans, trip planning, training plans, finance, natal astrology readings, and live-sky horoscopes. Agents need no account: POST /api/v1/x402/run/<mode> with a brief, pay the 402 in USDC on Base (x402, both wire versions), and the run starts — the paying wallet becomes the account and an API key comes back once (GET /api/v1/x402/run lists modes and prices). Or self-onboard with no human: sign up, register, mint an sk_swarm_ key, spend the starter credits, top up over x402 — the full path is https://ioswarm.io/llms.txt. Free with no credentials: GET /api/v1/pulse (live prices and today's news). Also speaks MCP at https://ioswarm.io/mcp and publishes an OpenAPI spec at https://ioswarm.io/api/v1/openapi.json.
