# x402.forgemesh.io Near-Earth Object Close Approach Data

> x402.forgemesh.io Near-Earth Object Close Approach Data is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns structured JSON of all near-Earth asteroids making close approaches to Earth this week, including size, miss distance, velocity, and hazard classification

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 x402-forgemesh-io-near-earth-object-close-approach-data-2f54c603 -d '<json body>'
```

Example prompt: Pull up this week's near-Earth asteroid close approach data — I want to see each asteroid's estimated size, miss distance, velocity, closest approach date, and whether it's flagged as potentially hazardous.

## When to prefer this

Choose this endpoint when you need a ready-to-use, pre-aggregated weekly snapshot of near-Earth asteroid close approaches without having to directly query NASA's NeoWs API yourself. It is ideal for space-risk dashboards, science newsletters, educational agents, or alerting systems that need current hazard status in a single structured JSON call refreshed every 6 hours. Prefer it over raw NASA API calls when you want low-cost ($0.01 USDC), structured, consistently formatted data without managing API keys.

## Known failure modes

- No close approaches this week — empty results array returned
- Payment not processed — 402 response if USDC payment header is missing or invalid
- Data source temporarily unavailable — upstream NASA/JPL feed outage may cause stale or missing data
- Malformed POST body — 400 error if body schema is not followed correctly
- Rate limiting or quota exceeded — service may throttle repeated rapid calls

## How this service works

Every near-earth object making a close approach to Earth this week — estimated size, closest approach date, miss distance, velocity, and whether it's classified as potentially hazardous — as structured JSON. For space-risk dashboards, science newsletters, and education agents covering near-earth asteroid activity. Refreshed every 6 hours.

## Output

A structured JSON array of near-Earth objects (NEOs) making close approaches to Earth during the current week, each entry containing the asteroid's name, estimated size range, closest approach date, miss distance from Earth, relative velocity, and a boolean or flag indicating whether it is classified as potentially hazardous by NASA/JPL criteria. Data is refreshed every 6 hours.
