Halowerk MMR Matchmaking Pair Selector
x402
Halowerk MMR Matchmaking Pair Selector is a paid API for AI agents from gaming.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).
Enumerates feasible player pairs from a pool, ranks them by rating gap then worst latency, and greedily selects disjoint matched pairs within configurable skill and latency constraints.

How this service works
Enumerates feasible player pairs, ranks them by rating gap then worst latency, and greedily selects disjoint pairs. This is a transparent local pairing heuristic, not globally optimal team balancing, skill inference, anti-smurfing, or a live queue service.
Output
Returns a list of greedily selected disjoint player pairs that satisfy the max_rating_gap and max_latency_ms constraints, ranked by rating gap and then worst latency among feasible pairs. Includes the paired player IDs and the metrics used for ranking each pair.
Example use cases
Casual lobby matchmaking before game start
“I've got 12 players in the pregame lobby with their MMR scores and pings. Pair them up into fair 1v1 matchups — keep the skill gap under 150 points and only match people with under 100ms latency to each other.”
Ranked queue snapshot pairing
“Here's a snapshot of 20 ranked players currently queued, each with their rating, uncertainty, and measured latency. Run the greedy pairing on them with a max rating gap of 300 and max latency of 60ms and tell me which pairs got selected.”
Custom tournament bracket seed pairing
“For our weekend tournament I have 16 registered players with their current ratings and connection latencies. Pair them up for round one — I want matches where the rating gap stays within 250 and no pair has a connection worse than 120ms.”
Technical details
Endpoint
POSThttps://gaming.halowerk.com/v1/matchmaking-mmrWhen to prefer
Use this endpoint when you have a known pool of players (2–500) with pre-measured latency and existing skill ratings and need a fast, deterministic, locally computed greedy pairing — not a global queue, live matchmaking service, anti-smurfing system, or team-balancing optimizer. Ideal for lobby-side or tournament-bracket pairing where you control the player set and want transparent, reproducible pair selection.
Side effects
- Fewer than 2 players provided — no pairs can be formed
- All player combinations exceed max_rating_gap or max_latency_ms thresholds — returns empty pair list
- Player data missing required fields (player_id, rating, rating_uncertainty, latency_ms) — validation error
- More than 500 players submitted — exceeds maxItems constraint
- Latency or rating values out of declared range — schema validation failure
