The stock alerts API.

An alert is a query with a delivery attached. Write the condition as SQL over 419+ precomputed signals, and Tickerbot watches the whole market for you — when a ticker enters the result, your endpoint gets a signed webhook, retried until it lands. No polling loop, no indicator pipeline, no server babysitting a watchlist. Data included.

Free plan. Every ticker, every signal, real-time data, all-time history.

what you get

The capability, itemized.

The conditionAny SQL predicate — rsi_14 < 25 AND market_cap > 1e9 — over every ticker and signal
The deliverySigned webhook POSTs (HMAC), retried on failure, with delivery logs you can read back
Discord tooPoint the same alert at a Discord channel with no server in between
Whole-marketConditions evaluate against every US equity — not a hand-picked watchlist
State, not spamFires on entering the matching state — a change of answer, not a repeat of it
ManageableCreate, list, pause and delete alerts by API; test-fire before going live

Every read runs in three tenses: live, as of any past moment (add ?asof=; no look-ahead, no survivorship bias), or on push — the same query as a webhook that fires when the answer changes. Under it sits the computed table: every US equity plus rates, FX and crypto, every signal precomputed and refreshed continuously, all-time history. Data included — there’s no feed to bring.

one call

An alert is one POST.

The trigger is the same SQL that powers screens; the delivery is a URL. That’s the whole object:

POST /v2/webhooks
{
  "trigger": { "type": "scan", "q": "rsi_14 < 25 AND market_cap > 1e9" },
  "target_url": "https://your-app.example/hook",
  "name": "oversold-large-caps"
}

// → { "id": "wh_…", "q": "rsi_14 < 25 AND market_cap > 1e9",
//     "cadence": "realtime", "target_url": "…", … }

Deliveries are HMAC-signed so your handler can verify origin, and failed sends retry on a schedule. The same trigger can target Discord directly via discord_url.

questions

FAQ

Is there an API for stock price alerts?

Yes — and not just price. Any condition you can write over the 419+ signal columns can be an alert: price levels, RSI thresholds, moving-average crosses, volume spikes, fundamentals. The condition is SQL; the alert is that query subscribed to a webhook.

How is this different from polling an API on a timer?

Polling re-asks a question your code then has to diff; an alert here is server-side state-watching — Tickerbot evaluates the condition continuously and calls you when the answer changes. You skip the scheduler, the diffing logic, and the rate-limit budget a polling loop burns.

Why does a trading system need computed state?

Because every action it takes — an alert, a screen result, an order — is a condition over derived values: RSI below 30, price above the 200-day average, volume three times normal. Raw data doesn’t contain those. Something has to compute and refresh them for every symbol, continuously, and keep the history so past answers are reproducible. That’s a data pipeline, not a feature — you either build and operate it, or query one that already runs.

How does Tickerbot work with AI agents?

Every call here is also a native tool call: install the MCP server and Claude, ChatGPT, Cursor, or any MCP runtime queries the market directly. Computed state is what makes that work well: hand a model raw data and its context window fills with math to do; hand it computed answers and the context goes to decisions. A scan returns the tickers matching your condition: a list, not a workload.

How does Tickerbot pricing work?

The Free plan needs no card and carries the full data side: every ticker, every signal, real-time data, all-time history and as-of queries, at 10,000 calls a month and 60 a minute. Paid plans start at $29/mo, remove the monthly cap, and raise the rate limit; webhooks and streaming come with them. Data depth is never a tier lever: every plan sees the same table.
