Realtime NBA Sportsdata and analytics for Prediction Markets

Request NBA sports data (schedule, boxscore, standings, injuries, roster, etc.) from the Daredevil seller. Payment per request via x402.

Daredevil NBA Sports Data

Use this skill in two ways:

1. Raw data — When the user asks for NBA schedule, scores, boxscore, standings, injuries, team roster, or player stats, request data from the Daredevil seller. Each request is paid via x402 (small fee per query).
2. Analysis / prediction — When the user asks for an opinion, recommendation, or "what do you think?" about a game or matchup (e.g. "What do you think about the LAL and CHI game?"), first retrieve the necessary raw data via this skill, then synthesize an answer using your LLM. Synthesis runs on your side (the buyer); the seller only returns raw data.

Base URL

https://daredevil-acp-seller-production.up.railway.app

• Health check (no payment): GET /health
• Data (payment required): POST /v1/data with JSON body and x402 payment headers

Request (POST /v1/data)

Send a JSON body with:

Field	Required	Description
dataType	Yes	One of: schedule, next_game, boxscore, live_score, play_by_play, standings, injuries, team_roster, player_stats
teamName	No	Team alias (e.g. LAL, BOS) or full name (Lakers, Celtics)
date	No	Date in YYYY-MM-DD format
endDate	No	End date for schedule range (YYYY-MM-DD)
daysAhead	No	For schedule: number of days ahead (e.g. 7 for one week)
maxDaysAhead	No	For next_game: max days to look ahead (default 14)
nextGameLimit	No	For next_game: max number of games to return (default 1)
gameId	No	Sportradar game ID when you need a specific game (boxscore, live_score, play_by_play)

Data types

• schedule — NBA games for a date or range (use date, endDate, or daysAhead; optional teamName to filter).
• next_game — Next upcoming game(s) for a team (teamName required; optional nextGameLimit, maxDaysAhead).
• boxscore — Full boxscore for a game (gameId or teamName for today’s game).
• live_score — Live score for a game (gameId or teamName for today’s game).
• play_by_play — Play-by-play for a game (gameId or teamName for today’s game).
• standings — NBA standings (optional date).
• injuries — Current injury report.
• team_roster — Team roster (teamName required).
• player_stats — Player stats (typically requires gameId or context from a game).

Payment (x402)

The server requires payment for POST /v1/data. Use an x402-capable HTTP client:

1. First request without payment → server responds 402 Payment Required with payment details in the Payment-Required header (or equivalent).
2. Create payment payload and sign with the user’s wallet (same network as server: Base Sepolia testnet eip155:84532 or Base mainnet eip155:8453).
3. Retry POST /v1/data with the same body plus the x402 payment header(s). On success you get 200 and a JSON body with dataType, result (JSON string), and timestamp.

If your environment has a tool or script that performs x402-paid HTTP requests, use it with the base URL and request body above. Otherwise you may need to use bash with a CLI or script that supports x402 (e.g. Node script using @x402/core client).

Response

Success (200) body shape:

{
  "dataType": "schedule",
  "result": "<JSON string of the actual data>",
  "timestamp": "2025-02-21T...",
  "gameStatus": "optional for live games"
}

Parse result as JSON to get the underlying schedule, boxscore, standings, etc.

Examples (raw data)

• "What's the Lakers schedule this week?" → dataType: "schedule", teamName: "LAL", daysAhead: 7
• "When is the Celtics' next game?" → dataType: "next_game", teamName: "BOS"
• "NBA standings" → dataType: "standings"
• "Lakers roster" → dataType: "team_roster", teamName: "LAL"
• "Current NBA injuries" → dataType: "injuries"

Analysis and synthesis workflow

When the user asks for an analysis, prediction, or opinion (e.g. "What do you think about the LAL and CHI game?", "Who do you think will win Lakers vs Celtics?", "Should I bet on the Bulls tonight?"):

1. Determine required data — For a matchup or game question, typically fetch:
   • next_game for each team (or schedule with teamName and daysAhead) to get game time and matchup.
   • standings for context on team records.
   • injuries for key absences (optional but recommended).
   • boxscore or live_score if the game is today and you need current state.
   • team_roster only if roster context is relevant.
2. Request that data — Call POST /v1/data (with x402 payment) for each needed dataType. Parse each result as JSON.
3. Synthesize — Using your LLM, produce a short analysis or prediction based only on the retrieved data. Do not invent stats or facts. Use the prompt template below (or see prompts/analyze-game.md) with the user's question and the concatenated/summarized retrieved data.

Synthesis prompt template

After you have the raw data, call your LLM with a prompt like this (fill in the placeholders):

You are an NBA analyst. The user asked: "{{user_question}}"

Below is raw data from the Daredevil NBA API (schedule, boxscore, standings, injuries, etc.). Use only this data to produce a short, clear analysis or prediction. Do not invent facts or stats.

---
{{retrieved_data}}
---

Provide your analysis or prediction in a few sentences.

• {{user_question}} — The user's exact question (e.g. "What do you think about the LAL and CHI game?").
• {{retrieved_data}} — The JSON or a concise summary of the API responses you received (schedules, standings, injuries, boxscore, etc.). If large, summarize key fields (teams, dates, scores, records, notable injuries) rather than pasting entire payloads.

Then return the LLM's synthesized answer to the user.

Examples (analysis)

• "What do you think about the LAL and CHI game?" → Fetch next_game for LAL and CHI, standings, and optionally injuries; then run the synthesis prompt with that data.
• "Who wins Lakers vs Celtics?" → Same: next games / schedule for both, standings, injuries; then synthesize.
• "Give me a pick for tonight's games" → Fetch schedule for today (or daysAhead: 1), standings, injuries; then synthesize picks from the data.

Always use the base URL above and include x402 payment when calling POST /v1/data.
