}Response
The outputSchema is the CLOSED model contract for structuredContent (top-level additionalProperties: false), answer-first fixed key order: source, tool, endpoint, request (echoed arguments), answer (authoritative result summary — answer from this and data), data (the complete result), included/included_digest (full expansion rows + a compact digest, when paid include expansions were served), units, answerable_fields, warnings, citations (complete visible citation array), usage (per-call cost truth), validation, and pagination (cursor/has_more/effective_limit/requested_limit). The single content block is a short plain-text answer card mirroring the same facts (header, Answer, Units, Warnings, Usage, Source). Errors return a plain-text error card and attach NO structuredContent. See How to cite ForceX MCP results.

}Notes
- Cost: Free. Costs and tier limits match the wrapped Xtract REST endpoint — see
get_developer_limits. - Wrapped REST endpoint: /xtract/docs/reference/developer-limits/ — the full parameter, response, and methodology reference.
- Data-retrieval tool: it never creates blockchain transactions, signs messages, publishes content, or changes third-party state (
openWorldHint=false,destructiveHint=false). Successful calls consume Xtract credits and record usage on your ForceX account, soreadOnlyHint=false.
