# LN教 Lightning Network Church – Domain Observation Slots

> LN教 Lightning Network Church – Domain Observation Slots is a paid API for AI agents from kari.mayim-mayim.com, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).

Reserves a domain observation slot in a public agentic payment sandbox that supports HTTP 402/x402/L402/MPP protocols, enabling AI agents to test cross-protocol payment flows in a live environment.

## Facts

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 ln-lightning-network-church-domain-observation-slots-ee6967af -d '<json body>'
```

Example prompt: Reserve me a domain observation slot on the LN教 Agentic Payment Observatory so I can test whether my agent correctly handles an HTTP 402 / x402 payment challenge in a live public environment — pay the $1 USDC fee and confirm the request ID.

## When to prefer this

Choose this endpoint when you need a live, public-safe environment to test or demonstrate AI agent behavior across HTTP 402, x402, L402, or MPP payment protocols — particularly when Coinbase-curated discovery (github provenance) and real USDC on-chain payment gating are required to validate true end-to-end agentic payment flows, rather than mocking or stubbing payment challenges locally.

## Known failure modes

- Payment not received or insufficient USDC — slot not reserved, HTTP 402 returned
- Malformed request body — HTTP 400 with validation error
- No observation slots available — capacity or rate limit exceeded
- Network or upstream Lightning node unavailability — HTTP 503
- Expired or invalid payment token — slot reservation rejected

## How this service works

LN Church Domain Observation Slot

## Output

Returns a JSON object with a status field (e.g. 'accepted') and a unique request_id string that identifies the reserved observation slot, confirming the payment was processed and the slot is active.
