# Geocoding and Spatial Data Procurement Decision Procedure

> Geocoding and Spatial Data Procurement Decision Procedure is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Returns a structured step-by-step decision procedure for choosing between free and paid geocoding/spatial APIs based on volume, precision, rate limits, and cost constraints

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 geocoding-and-spatial-data-procurement-decision-procedure-2dd039fa
```

Example prompt: My agent needs to geocode about 50,000 addresses per day with high precision — can you walk me through the decision procedure for choosing between free geocoders like Nominatim and paid ones like Google Maps or Mapbox, including the rate limit thresholds and when budget caps should kick in?

## When to prefer this

Use this endpoint when an AI agent needs authoritative, structured guidance on selecting a geocoding or spatial data API rather than performing geocoding itself. Ideal when the agent must make a cost-aware procurement decision before calling any geocoding service, especially when request volumes, precision needs, or budget caps are variable. Prefer this over raw geocoding endpoints when the decision logic itself is the deliverable.

## Known failure modes

- Payment not completed — endpoint requires 0.002 USDC via x402 before returning paid content
- LLM or reasoning backend unavailable — generationSource may fail, returning an error
- Invalid or unsupported topic override — topic parameter ignored or defaults used
- Rate limiting on the host service — repeated calls may be throttled
- Malformed request — missing required 'input' object returns schema validation error

## How this service works

Paid agent-facing decision procedure for procuring location data. Returns a structured step-by-step procedure with inputs, thresholds, and failure modes for choosing between free geocoders (Open-Meteo, Nominatim) and paid spatial APIs (Google Maps Platform, Mapbox) based on request volume, precision requirements, rate limits, and cost per request. Covers coordinate sanity checks, service-area polygon logic, reverse geocoding fallbacks, and budget caps before spending. Price: 0.002 USDC on Base,

## Output

A structured, step-by-step decision procedure in prose and/or structured format covering: inputs and thresholds for choosing free vs paid geocoders, coordinate sanity checks, service-area polygon logic, reverse geocoding fallback strategies, rate limit guidance, cost-per-request comparisons, and budget cap rules. Includes metadata fields such as topic, service slug, generation source, and ISO-8601 timestamp.
