# Pinloft Reverse Geocoder: Coordinates to Census Codes

> Pinloft Reverse Geocoder: Coordinates to Census Codes is a paid API for AI agents from pinloft.cybermax-tools.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Converts latitude/longitude coordinates into US Census tract codes, district identifiers, and location context via reverse geocoding

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pinloft-reverse-geocoder-coordinates-to-census-codes-21acb38c
```

Example prompt: What US Census tract and district does the coordinate 40.7128, -74.0060 fall in? Also check 34.0522, -118.2437 and 41.8781, -87.6298 while you're at it.

## When to prefer this

Choose this endpoint when you already have latitude/longitude coordinates and need to map them to US Census geographies (tracts, districts) — for demographic analysis, compliance reporting, or data enrichment. It supports up to 5 coordinate pairs per call, making it efficient for small batches. Prefer this over forward geocoders when you're starting from GPS data rather than street addresses.

## Known failure modes

- Non-US coordinates return no Census match (Census data only covers US territory)
- Invalid lat/lon values (out of range or malformed) return an error
- Exceeding 5 coordinate pairs in a single request may be rejected
- Payment failure or insufficient USDC balance blocks the request
- Remote locations (US territories without full Census coverage) may return partial results

## How this service works

Address lists to map coordinates and Census codes. Batch geocoding with the Census tract and district for every US address Try it free in one click, no sign-up.

## Output

Returns Census tract identifiers, Census district codes, and associated geographic metadata for each submitted coordinate pair. Up to 5 coordinate pairs can be submitted per request using the pipe-separated coords parameter.
