# Orbitwren Changes API — Daily Change Log for Space AI Compute Projects

> Orbitwren Changes API — Daily Change Log for Space AI Compute Projects is a paid API for AI agents from orbitwren.cybermaxtools.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-01).

Returns a paginated daily change log of additions and updates to orbital data center and space AI compute projects, launches, and related data

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 orbitwren-changes-api-daily-change-log-for-space-ai-compute-projects-d8b8c12d
```

Example prompt: Pull the last 100 changes from Orbitwren's changelog since 2025-01-01 so I can see which orbital data center projects or compute satellite launches have been updated or added recently.

## When to prefer this

Use this endpoint when you need to detect what has changed in the orbital data center and space AI compute tracking dataset over time — ideal for polling, alerting, audit trails, or catching up after an offline period. Prefer this over the full project or launch listing endpoints when you only care about deltas rather than the complete current state.

## Known failure modes

- Invalid 'since' date format returns a 400 error
- Limit out of range (< 1 or > 200) may return validation error or be clamped
- Empty result set if no changes occurred since the specified date
- Payment not accepted or insufficient USDC balance returns 402
- Network timeout on large result sets near the 200-row limit

## How this service works

Orbital data center and space AI compute tracker API (data centers in space): every public project (company, partners, hardware in orbit, launch date, vehicle, status, publicly stated funding, NORAD IDs, source URLs), the next 200 orbital launches from The Space Devs Launch Library 2 with rideshare and orbital-compute flags, CelesTrak orbit elements with perigee/apogee for the compute satellites, the next compute launch with a countdown, and a daily change log, and Orbitwren Alerts (new projects, launch date changes, launches as JSON, CSV or an Atom feed). REST + MCP server.

## Output

A JSON array of change log entries, each describing what was added or updated (e.g. new orbital compute project, launch date change, new NORAD ID, funding update), filtered by the 'since' date and capped at the specified limit (default 50, max 200).
