> OneShot Agent – LinkedIn Post React is a paid API for AI agents from win.oneshotagent.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

## 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 oneshot-agent-linkedin-post-react-21ca7a90 -d '<json body>'
```

Example prompt: React to LinkedIn post urn:li:activity:7234567890123456789 with a 'celebrate' reaction using my connected account acc_abc123.

## When to prefer this

Choose this endpoint when you need to programmatically react to a specific LinkedIn post using a pre-connected LinkedIn account in an autonomous agent workflow. It is ideal for social engagement automation, lead-nurture warm-up sequences, or brand community management where reactions need to be triggered based on external signals or schedules. Prefer this over manual LinkedIn interaction or browser automation when you need reliable, structured reaction delivery with async confirmation.

## Known failure modes

- Invalid or expired LinkedIn account_id — LinkedIn auth may have been revoked
- Malformed post_id (not a valid urn:li:activity or urn:li:ugcPost URN) causing 400 Bad Request
- Post already reacted to with the same reaction type — LinkedIn may reject duplicate reactions
- Rate limiting from LinkedIn's underlying API causing downstream failure
- 402 Payment Required if x402 payment header is missing or signature is invalid
- Polling timeout if the async result takes longer than expected

## How this service works

Tools, payments, and compute orchestration for autonomous AI agents.

## Authentication

- **`x402Payment`** — paid tool endpoints use the [x402 payment protocol](https://x402.io).
  First call returns `402 Payment Required` with a quote; sign and resend the request
  with `Authorization: <signed payment header>` and `X-Quote-ID: <quote_id>`.
- **`agentId`** — free read-only endpoints accept `X-Agent-ID: <wallet>` (0x… address).
- **`soulKey`** — soul marketplace seller dashboard uses `Authorization: Bearer soul_…`
  (issued by `POST /v1/soul/register`).
- **`acpBearer`** — Stripe ACP checkout sessions use a separate bearer token plus the
  `API-Version: 2026-01-30` header.

## Async tools & polling

Most tool endpoints return `202 Accepted` with `{ request_id, tool, status }`. Poll
`GET /v1/requests/{id}` (with the same `X-Agent-ID`) to retrieve the final result.
A WebSocket fallback is available at `wss://<host>/v1/requests/subscribe`.
