Geo API, webhooks and MCP

Everything a paid Geo plan gives a program: the records over REST, a CSV export, signed webhooks the minute a record is written, and an MCP server for AI assistants. One key opens all of it. The free pages and the open JSON at /geo/api stay free and need no key.

Machine-readable: OpenAPI 3.1 for both the free JSON and the paid API.

Quick start

1. Take the API or Team plan.
2. Open Account, Geo, API keys and create a key. It starts with gk_ and is shown once.
3. Call the API with the key as a Bearer header:

curl -H "Authorization: Bearer gk_YOUR_KEY" \
  "https://geo.firmtape.com/v1/items?country=IR&min_severity=2&limit=20"

Limits

The month is the calendar month in UTC. GET /v1/usage is free and says where you stand; the account page shows the same numbers.

Records

GET https://geo.firmtape.com/v1/items

Newest first. When more records match, next holds the full URL of the next page; each page is one call. Times are UTC. Each record:

{
  "uid": "8f1c2a90d4b7e613",
  "feed": "faa_tfr",
  "sector": "air",
  "type": "new",
  "category": "security",
  "severity": 2,
  "routine": false,
  "countries": ["US"],
  "region": "north_america",
  "title": "FAA flight restriction: VIP movement, Washington DC",
  "summary": "",
  "published_utc": "2026-09-17T13:02:11Z",
  "event_utc": "2026-09-18T14:00:00Z",
  "first_seen_utc": "2026-09-17T13:04:02Z",
  "backfill": false,
  "source": "FAA",
  "url": "https://tfr.faa.gov/...",
  "attribution": null,
  "value": null, "baseline": null, "score": null,
  "lat": 38.89, "lon": -77.03,
  "facts": {}
}

routine marks the records the pages hide by default (gunnery exercises, small quakes, green alerts). backfill marks a record found in a source's own history rather than caught live. value, baseline and score are set on spikes: what was measured, its own normal, and the ratio.

GET /v1/sources

Every feed with its source name, when it last answered and how many reads in a row failed.

GET /v1/usage

{ "tier": "api", "month": "2026-09", "calls": 4210, "limit": 20000 }

CSV export

GET /v1/export.csv?since=…&until=…

The same filters as /v1/items, every matching record in one file with every column. A call covers at most 7 days on API and 31 on Team, and counts as one call.

curl -H "Authorization: Bearer gk_YOUR_KEY" -o week.csv \
  "https://geo.firmtape.com/v1/export.csv?since=2026-09-07T00:00:00Z&until=2026-09-14T00:00:00Z"

Webhooks

1. In Account, Geo, Webhooks add a public https:// address. Copy the signing secret (whsec_…); it is shown once.
2. In Account, Geo, Alerts add a rule and tick Webhooks. Every record the rule matches is posted to each of your endpoints the minute it is written.
3. Press Test next to the endpoint to receive a geo.test event.

Each delivery is a POST with a JSON body. Answer with any 2xx within 10 seconds. A delivery is attempted once; its status code and time show under Webhooks in the account, where a failed delivery can be retried. Up to 600 records an hour go to one account's webhooks.

POST /your/path
Content-Type: application/json
X-FirmTape-Webhook-Id: 4k2p9x1m7q3r8s
X-FirmTape-Signature: t=1789650131,v1=5f0c…

{
  "event": "geo.record",
  "sent_utc": "2026-09-17T13:02:12Z",
  "record": { "uid": "8f1c2a90d4b7e613", "feed": "faa_tfr", "sector": "air", "severity": 2, "title": "…", "url": "…", … }
}

Verify the signature

v1 is the hex HMAC-SHA256 of t + "." + raw body with your secret. Compare it in constant time and reject old t values.

// Node.js
const crypto = require("node:crypto");
function verify(rawBody, header, secret) {
  const { t, v1 } = Object.fromEntries(header.split(",").map((p) => p.split("=")));
  if (Math.abs(Date.now() / 1000 - Number(t)) > 300) return false;
  const mac = crypto.createHmac("sha256", secret).update(`${t}.${rawBody}`).digest("hex");
  return crypto.timingSafeEqual(Buffer.from(mac), Buffer.from(v1));
}

# Python
import hmac, hashlib, time
def verify(raw_body: bytes, header: str, secret: str) -> bool:
    parts = dict(p.split("=", 1) for p in header.split(","))
    if abs(time.time() - int(parts["t"])) > 300:
        return False
    mac = hmac.new(secret.encode(), f"{parts['t']}.".encode() + raw_body, hashlib.sha256).hexdigest()
    return hmac.compare_digest(mac, parts["v1"])

MCP for AI assistants

Endpoint https://geo.firmtape.com/mcp (streamable HTTP), with the same key as a Bearer header. Tool calls count toward the month's calls; listing tools does not. Tools:

Claude Code

claude mcp add --transport http firmtape-geo https://geo.firmtape.com/mcp \
  --header "Authorization: Bearer gk_YOUR_KEY"

Cursor, Windsurf and other clients that take headers

{
  "mcpServers": {
    "firmtape-geo": {
      "url": "https://geo.firmtape.com/mcp",
      "headers": { "Authorization": "Bearer gk_YOUR_KEY" }
    }
  }
}

Claude Desktop

{
  "mcpServers": {
    "firmtape-geo": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://geo.firmtape.com/mcp", "--header", "Authorization:${GEO_AUTH}"],
      "env": { "GEO_AUTH": "Bearer gk_YOUR_KEY" }
    }
  }
}

Then ask, for example: "What notable Geo records mention Iran this week? Cite each source." Geo is not on FirmTape's free MCP server; it lives here, behind the key.

Errors

Credit

Every record carries its source and url, and attribution where the source asks for a specific citation (UCDP, GDACS, Copernicus, RIPE NCC and others). Show them next to anything you display. Team may show records to its own customers with that credit; no plan allows reselling the records as a feed. Records are public information with their time and source: context for a session, never a trading signal.
