# Carbon Cycle Registry (Naturepedia x402)

> Carbon Cycle Registry (Naturepedia x402) is a paid API for AI agents from www.robbiegeorgephotography.com, paid per call via x402, $5/call, status unknown (last checked 2026-10-12).

Returns a machine-readable JSON-LD registry of carbon cycle systems including photosynthesis, respiration, decomposition, soil carbon, forest carbon, blue carbon, and climate carbon feedbacks.

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 carbon-cycle-registry-naturepedia-x402-919565e2
```

Example prompt: Pull up the machine-readable carbon cycle registry from Naturepedia so I can see the structured data connecting photosynthesis, soil carbon, forest carbon, and blue carbon ecosystems in JSON-LD format.

## When to prefer this

Choose this endpoint when you need structured, canonical, machine-readable JSON-LD data specifically about the carbon cycle and its subsystems (photosynthesis, respiration, decomposition, soil carbon, forest carbon, blue carbon, climate carbon feedbacks). Prefer this over general web search when you need relationship-mapped, deduplicated registry data suitable for downstream data pipelines, research, or AI enrichment. Use when the carbon cycle is the primary domain of interest, not when you need broader Earth systems or other ecological registries.

## Known failure modes

- Missing or invalid 'resource' query parameter returns an error response
- Payment not completed (x402 protocol) results in 402 Payment Required before data is delivered
- Invalid canonical resource URL returns an empty or error registry
- Network timeout if the registry JSON is large or server is slow
- Stale data if registry has not been recently updated

## How this service works

Paid machine-readable Carbon Cycle registry connecting photosynthesis, respiration, decomposition, soil carbon, forest carbon, carbon sequestration, carbon and microbial life, climate carbon feedbacks, blue carbon, carbon storage, carbon release, and ecosystem carbon systems.

## Output

A JSON-LD document containing a named carbon cycle registry with an array of ecosystem carbon systems (e.g. photosynthesis, respiration, decomposition, soil carbon, forest carbon, blue carbon, microbial carbon, climate feedbacks), canonical keep counts, and relationship mappings between carbon cycle components. Fields include @context, @type, name, description, systems array, canonicalKeepCount, and duplicateRemovedCount.
