research.org

Resolve a research organization via the Research Organization Registry (ROR). Pass id (a ROR id like 056y0v115 or its full URL) to fetch one org, or name to search by free text. Returns the canonical ROR id and name, organization type, status, founding year, location (city, country, GeoNames coordinates), website, Wikipedia link, external identifiers (GRID, ISNI, Wikidata, Crossref Funder), parent/child relationships, and aliases/acronyms. Data: ROR, free and CC0. The canonical institution key in scholarly metadata — pair with /api/papers/search and /api/paper/doi-lookup (author affiliations) and /api/research/author (ORCID). Use to disambiguate an institution name to a stable id before joining datasets.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/research/org?id=xx&name=xx&limit=5'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/research/org?id=xx&name=xx&limit=5' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/research/org?id=xx&name=xx&limit=5'

MCP — Claude Desktop / AgentKit / any MCP hostjson

// 1. Add @2sio/mcp to your MCP host config (Claude Desktop example below).
//    EVM_PRIVATE_KEY funds x402 payments per call.

// claude_desktop_config.json
{
  "mcpServers": {
    "2sio": {

      "args": ["-y", "@2sio/mcp"],
      "env": { "EVM_PRIVATE_KEY": "0x..." }
    }
  }
}

// 2. Once the server is running, agents call this tool via standard MCP:
