DawBets Public API

What it is for

Agents and integrators kept scraping the marketing pages for facts that a JSON endpoint states better: which books we cover, what a state allows, what a plan costs, and what "EV" means on a DawBets card. This API is those facts, versioned, with the same rate limits and error shape on every route. Point a client generator at /openapi.json and every operation below has a stable operationId.

• Base URL https://dawbets.com, HTTPS only.
• Every response is application/json. Every date is ISO-8601 in UTC.
• No API key, no OAuth, no CORS restrictions on the spec itself.

Endpoints

curl "https://dawbets.com/api/sportsbooks"

[
  {
    "id": "bet365",
    "name": "bet365",
    "logo": "sportsbooks/bet365",
    "fee_percentage": 0,
    "desktop_link_cta": "Go to market page",
    "mobile_link_cta": "Add to slip",
    "is_prediction_market": false
  },
  {
    "id": "kalshi",
    "name": "Kalshi",
    "logo": "sportsbooks/kalshi",
    "fee_percentage": 0,
    "desktop_link_cta": "Add to slip",
    "mobile_link_cta": "Add to slip",
    "is_prediction_market": true
  }
]

curl "https://dawbets.com/api/state-sportsbooks?state=NJ"

{
  "sportsbooks": [
    "draftkings",
    "fanduel",
    "betmgm",
    "caesars"
  ]
}

curl "https://dawbets.com/api/prices"

{
  "hasAnnual": true,
  "plus": {
    "monthly": "$19",
    "annual": "$15",
    "annualTotal": "$190"
  },
  "pro": {
    "monthly": "$30",
    "annual": "$25",
    "annualTotal": "$300"
  }
}

curl "https://dawbets.com/api/methodology"

Rate limits

Each endpoint has its own per-IP sliding window, listed above and in the spec as x-rate-limit. Exceed it and you get HTTP 429 with a Retry-After header holding the seconds until the window resets; wait that long and retry. Cached endpoints rarely reach the limiter — the shared cache answers repeat requests — but a loop over distinct state values misses the cache every time and is counted.

Error shape

Every non-2xx response is the same JSON object. statusCode and statusMessage are always present; data carries validation detail (an issues array) when there is any.

{
  "error": true,
  "url": "https://dawbets.com/api/state-sportsbooks",
  "statusCode": 400,
  "statusMessage": "state query parameter is required"
}

• 400 — a required parameter is missing or malformed.
• 429 — rate limit exceeded; honor Retry-After.
• 500 — the data behind the route could not be loaded; retry later.

Versioning and changelog

The spec carries a semantic version in info.version (currently 1.0.0). Adding a field or an endpoint is a minor bump; removing or renaming anything, or changing a type, is a major bump and is announced here first. Every change a client could notice is a line in x-changelog, newest first:

• 2026-09-03v1.0.0
  • Published the OpenAPI 3.1 document at /openapi.json.
  • Added GET /api/methodology.
  • Documented GET /api/sportsbooks, GET /api/state-sportsbooks and GET /api/prices, and put a per-IP rate limit on each.

Odds and EV for agents: the Claude connector

Live odds, fair prices, expected value and a user's own tracked bets are not part of this API. They are available to AI agents through the DawBets MCP server, which a subscriber connects to Claude with OAuth on /connect-claude. The connector is scoped to the signed-in user's own account, is not available on the Free plan, and requires a one-time confirmation of legal sports-betting age before any tool answers.

• MCP resource: https://dawbets.com/api/mcp
• RFC 9728 protected-resource metadata: https://dawbets.com/.well-known/oauth-protected-resource
• Ceilings: 120 tool calls per minute on every plan, and a daily quota per plan (2,500 Plus, 5,000 Pro) that resets at midnight UTC.

Terms

• The public API answers GET requests only and serves reference data only. It never serves odds, fair prices or EV.
• Use is governed by our Terms of Service and Privacy Policy. The citation policy in /llms.txt applies to anything you republish.
• The Claude connector is a per-user, account-bound service: the legal-age rules of the user's jurisdiction apply (21+ in most US states), and it is not offered as a data feed.
• We may change or withdraw an endpoint; a breaking change is a major version and appears in the changelog before it ships.
