# pipeworx `nominatim` — Nominatim

## Coverage
Forward and reverse geocoding using OpenStreetMap Nominatim

Catalog `tool_count`: 3. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/nominatim/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 39 tools: these 3 plus the 36 platform tools every pack endpoint lists.

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

- `search_address` — Search for coordinates of an address or place name. Required: `query`.
- `reverse_geocode` — Convert latitude/longitude coordinates to a human-readable address. Required: `lat`, `lon`.
- `lookup` — Get details for OpenStreetMap locations by ID (e.g., "N123456" for node, "W654321" for way, "R111" for relation). Required: `ids`.

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

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." 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: measured 100% over 21 synthetic checks in 7d (last checked 2026-10-01).

## 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.
