# AEML MCP Server Census Lookup

> AEML MCP Server Census Lookup is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns census/status record for a single MCP server by ID, including status, missing streak, lifecycle, and record hash, with degraded delivery noted for fields whose upstream collector is offline.

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 aeml-mcp-server-census-lookup-c3990971
```

Example prompt: What's the current census status, missing streak, and lifecycle info for MCP server 'my-server-id'? I also want to know the record hash and any fields that weren't available due to collector downtime.

## When to prefer this

Use this endpoint when you need point-in-time census data for a specific MCP server — particularly its availability status, consecutive missing streak, and lifecycle state. Prefer this over broader registry searches when you have a known server_id and need structured, hashed snapshot data. Note that popularity/maturity fields are currently degraded and unavailable.

## Known failure modes

- Missing or invalid server_id returns error or empty result
- Fields like prominence, maturity, github_stars, downloads are consistently unavailable due to upstream collector being offline (degraded delivery)
- Stale data: snapshot date is 2026-07-08 so data_age_hours may be large
- server_id not found in census returns status indicating missing
- Payment failure (x402) blocks the request entirely

## How this service works

[SIGNAL+PROOF] Census record for one MCP server (?name=): status, missing_streak, lifecycle, record_hash. DEGRADED DELIVERY, see unavailable_fields - prominence, maturity, github_stars, downloads and source_code_url have no data because the original collector stopped. Snapshot 2026-07-08. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

Returns a JSON object containing the server_id, current status string, lifecycle object (if available), record_hash, observed_at timestamp, capture_date, data_age_hours, missing_streak integer, source_tier, source_ref, and an unavailable_fields array listing fields (e.g. prominence, maturity, github_stars, downloads) that could not be populated because the upstream collector is offline, along with an unavailable_reason string explaining why.
