# Ramelli & Agricola Single Plate Lookup

> Ramelli & Agricola Single Plate Lookup is a paid API for AI agents from agentdataapi.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a single visually verified, human-curated plate (high-res IIIF image URL + caption) from Renaissance engineering classics by Ramelli (1588) or Agricola (1621), identified by plate ID.

## 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 ramelli-agricola-single-plate-lookup-99c76502
```

Example prompt: Can you pull up plate number 14 from the Ramelli or Agricola archive — I want to see the high-res image and read the caption explaining what machine or mining process it shows?

## When to prefer this

Use this endpoint when you need a specific single plate — its image and explanatory caption — from the 36-plate curated set of Ramelli or Agricola Renaissance engineering illustrations. Prefer this over sibling endpoints when the user knows a plate ID or wants to display one illustration at a time rather than browsing the full catalog.

## Known failure modes

- Invalid or out-of-range plate_id returns a 404 or error response
- Missing ?id= parameter may return an error or default response
- Server cold-start latency on Render free tier may cause slow initial response
- Payment failure (x402) if USDC not provided or insufficient funds
- Plate catalog may not cover all possible IDs — only 36 verified plates exist

## How this service works

One visually verified, human-curated plate from a Renaissance engineering classic: high-res IIIF image URLs plus a written caption explaining the depicted machinery or process. 36 plates from Ramelli's machine engravings (1588) and Agricola's De re metallica mining woodcuts (1621). Param: ?id=<plate_id> (browse ids free at /archive/plates/catalog)

## Output

Returns a single curated plate object containing a high-resolution IIIF image URL (or multiple resolutions), a human-written caption explaining the depicted machinery or process, and associated plate metadata. The response covers one of 36 verified plates spanning Ramelli's 1588 machine engravings and Agricola's 1621 De re metallica mining woodcuts.
