# OPC / 彼岸花开

> A one-person company (OPC) run by Lei Zhang in Hangzhou, China. Its agent-facing surface is a single A2A agent, "China On-Site Video Service": give it a Google Maps link or coordinates anywhere in China and a real local goes there and films ~10 minutes of unscripted footage, delivered by email as an MP4 for a fixed $50 USD. There is no OpenAPI, no MCP server, no SDK and no developer documentation; the agent card and the JSON-RPC endpoint are the whole machine-readable surface. This file was generated by API Evangelist from the provider's published agent card and service page (2026-09-19); the provider publishes no llms.txt of its own.

## Agent surface (A2A)

- [Agent card (legacy path, GET only)](https://bianhuakai.club/.well-known/agent.json): protocolVersion 0.3.0, preferredTransport JSONRPC, one skill `film_video_at_location`, securitySchemes empty (anonymous). The canonical /.well-known/agent-card.json is not served.
- [JSON-RPC endpoint](https://bianhuakai.club/a2a/): POST JSON-RPC 2.0; anonymous; returns -32601 for unknown methods. Fulfilment is by a human and confirmed by email, so task state read back via tasks/get is not reliable.

## Human-facing pages

- [Service page (English, pricing)](https://bianhuakai.club/lei/): what Lei films, how it works, fixed $50 per video / $50 per hour, paid by Wise, Panda Remit or Remitly.
- [Site root (彼岸花开 · 花灵)](https://bianhuakai.club/): a login-gated consumer chat app in Chinese; not a developer surface.

## Skill: film_video_at_location

- Input: a Google Maps link or coordinates of any place in China, plus what to film (text/plain or application/json).
- Output: confirmation over A2A; the ~10-minute MP4 arrives by email.
- Example prompts from the card: "Film West Lake, Hangzhou at 7am on a weekday"; "Film my grandfather's old neighborhood in Wenzhou, Zhejiang"; "Film the morning vegetable market in Chengdu".

## What is not published
