# pipeworx `census-trade` — Census Trade

## Coverage
US Census Bureau International Trade data — import/export values, trade balances, and monthly trends by commodity and country.

Catalog `tool_count`: 4. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/census-trade/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 40 tools: these 4 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `census_imports` — Search US import data by HS commodity code and/or country. Required: `year`.
- `census_exports` — Search US export data by HS commodity code and/or country. Required: `year`.
- `census_trade_balance` — Check US trade balance with a specific country for a given year. Required: `year`.
- `census_trade_trends` — Monthly US trade trends with ONE trading partner — month-by-month imports and exports for a country, optionally narrowed to an HS commodity, to show seasonality and shifts. No required arguments.

Client setup: `claude mcp add pipeworx-census-trade -- npx -y mcp-remote https://gateway.pipeworx.io/census-trade/mcp`.

## Auth
Catalog `auth.shape`: `platform-keyed`. Verbatim detail: "Pipeworx supplies the census-trade API key — no key needed from you. You may override it with `_apiKey`." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
