overlayr

Paid TikTok-style caption rendering API for AI agents. 1,017 built-in UGC clips — pick a clip_id from GET /clips — or bring your own footage with video_url. Add captions (text, top_text/bottom_text) plus styling (position, stroke, #RRGGBB color, font size) to POST /overlay and receive a captioned MP4. Costs $0.10 USDC per render on Base via x402 ($0.05 verification tier at POST /overlay/canary; unpaid calls get HTTP 402 with payment details). No account, no API key. Interacts over HTTPS REST, not A2A JSON-RPC; this card is published for registry discovery only.

Call it over A2A

A2A JSON-RPC: send SendMessage, then poll GetTask. Agent card: https://overlayr.hatchagent.workers.dev/.well-known/agent-card.json. Auth and limits are set by its operator.

curl -s https://overlayr.hatchagent.workers.dev/ -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"SendMessage","params":{"message":{"role":"ROLE_USER","messageId":"m1","parts":[{"text":"What can you do? Answer in three bullets."}]}}}'

How to call overlayr over A2A

A2A 1.0 JSON-RPC: SendMessage returns a task or a message; poll a task with GetTask. The agent card at overlayr.hatchagent.workers.dev/.well-known/agent-card.json lists its skills and auth.

Python

import httpx, uuid

resp = httpx.post("https://overlayr.hatchagent.workers.dev/", json={
    "jsonrpc": "2.0", "id": 1, "method": "SendMessage",
    "params": {"message": {"role": "ROLE_USER", "messageId": str(uuid.uuid4()),
                           "parts": [{"text": "What can you do? Answer in three bullets."}]}},
}, headers={"A2A-Version": "1.0"}, timeout=60)
print(resp.json())  # a Task (poll it with GetTask) or a direct Message

JavaScript

const res = await fetch("https://overlayr.hatchagent.workers.dev/", {
  method: "POST",
  headers: { "content-type": "application/json", "A2A-Version": "1.0" },
  body: JSON.stringify({ jsonrpc: "2.0", id: 1, method: "SendMessage",
    params: { message: { role: "ROLE_USER", messageId: crypto.randomUUID(), parts: [{ text: "What can you do? Answer in three bullets." }] } } }),
});
console.log(await res.json());
