Add SwarmIO Cloud

[TossAyeCoin]

Adds SwarmIO Cloud to Data & Research.

URL: https://ioswarm.io/.well-known/x402.json
Manifest: https://ioswarm.io/.well-known/x402.json
Endpoint: https://ioswarm.io/api/v1/search (POST — a bare GET intentionally serves the free-usage discovery doc; the 402 answers POST with no payment header, per the x402 spec)

Six pay-per-call research primitives over x402 (USDC on Base, no signup — the paying wallet is the account):

• POST /api/v1/search — live web search with citations, $0.02 (25 free/day per caller, then 402)
• POST /api/v1/search/report — one-call cited bullet brief, $0.05
• POST /api/v1/news/brief — one-call cited market-news brief, no input, $0.05
• POST /api/v1/quote — market quotes, $0.01
• POST /api/v1/fetch — browser-grade page fetch, $0.02
• POST /api/v1/chat — chat completions, $0.02
• 17-mode deep-research run catalogue, $0.25–$1.40 (GET /api/v1/x402/run)

x402 v1+v2 (EIP-3009 on Base, Coinbase CDP facilitator — passes its validator 25/25). Discovery: /.well-known/x402.json manifest, A2A agent card, OpenAPI 3.1, /mcp facade.

Gold-402 Verification: FAILED

URL checked: https://ioswarm.io (first url that is not a package, repo or social link)
Rule applied: service -- must answer HTTP 402
Reason: endpoint did not return HTTP 402 -- got 2xx response. x402 endpoints must return 402 Payment Required on unauthenticated requests.

A maintainer will still read this by hand -- the PR stays open.
Push a new commit, or edit the PR body, to re-run the check.

Common causes:

• The URL checked above is not the one you meant. The gate picks it in
  this order: a line starting URL:, Endpoint:, Service:, Manifest:
  or API:; then any /.well-known/x402 manifest link; then the first
  link that is not a package, repo or social page; and only if the
  description has no link at all, the link in the line you added to the
  shelf. Add a URL: line to say it outright.
• A service endpoint that does not answer HTTP 402 unauthenticated.
• A URL that is unreachable, times out, or sits behind a login.
• The entry is already listed.

Knocked live 2026-10-04: POST /api/v1/search → 402 at $0.02, and /search/report and /news/brief → 402 at $0.05, all x402 v2 exact on Base. My first unpaid call got the 402 straight away, so I couldn't reproduce the 25-free-per-day tier. Merging as written. Thanks.
