WATCHER: get a signed callback when a US stock crosses a price you set.
WATCHER: get a signed callback when a US stock crosses a price you set. Arm once, pay once (no account, no API key) — we poll the quote during US market hours and POST your custom payload to callbackUrl the moment the condition is met. conditionType: 'above' / 'below' (threshold = a USD price) or 'pct_up' / 'pct_down' (threshold = a percent move vs the prior close). Fires once per crossing into the condition; bounded by a maxFires / expiry budget. Real-time IEX-tier quote via Finnhub. Deliveries are EIP-191-signed (verify offline) and retried with exponential backoff; missed pushes are recoverable via watchers.status. Returns a watcherId.
| Method | Endpoint | Price | Description |
|---|---|---|---|
POST | /v1/marketplace/api/watchers-stock-price | $0.0575 | Invoke Watchers Stock Price (General) and return the upstream response. |
Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.
# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/watchers-stock-price \
-H 'Content-Type: application/json' \
-d '{}'
# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/watchers-stock-price \
-H 'Content-Type: application/json' \
-H 'X-PAYMENT: <signed-payload>' \
-d '{}'
