561-Group Pacing Analysis
x402
561-Group Pacing Analysis is a paid API for AI agents from market.561.group, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-14).
Analyzes caller-submitted biometric observations to produce a full pacing report including rolling baselines, morning deviation, resting-heart-rate threshold estimate, and PEM risk flag for ME/CFS energy management.

How this service works
Pacing Analysis: the full analyzePacing report over caller-submitted biometric observations -- rolling baselines, morning deviation, resting-heart-rate threshold estimate, and conservative PEM risk flags, each with citations and epistemic labels. Stateless: nothing submitted or computed is stored.
Output
Returns a full analyzePacing report containing: rolling heart rate baseline computed from submitted observations, morning deviation score relative to that baseline, an estimated resting-heart-rate-based pacing ceiling (Workwell Foundation +15 bpm heuristic), and a conservative binary PEM risk flag indicating whether the submitter is approaching or exceeding safe exertion limits.
Example use cases
Daily ME/CFS pacing check
“I have ME/CFS and want to check today's pacing status. Here are my resting heart rate readings and morning heart rates for the past 14 days — can you run the full pacing analysis and tell me my rolling baseline, morning deviation, my estimated heart rate ceiling, and whether I'm flagged for PEM risk?”
Wearable data PEM risk assessment
“I just exported two weeks of biometric observations from my fitness tracker including resting and morning heart rates. Can you submit these to the pacing analysis and give me back my rolling baseline trend, how much I've deviated in the mornings, and a conservative PEM risk flag?”
Post-flare recovery pacing review
“I had a crash last week and want to review my heart rate data from before and during the flare to understand my pacing patterns. Please run a full analyzePacing report on these observations and show me where my resting heart rate threshold sits and whether the morning deviation signaled the crash coming.”
Technical details
Endpoint
POSThttps://market.561.group/v1/pacing/analysis?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call pacing report that combines rolling baseline computation, morning deviation scoring, HR threshold estimation, and PEM risk flagging in one response — especially for ME/CFS or similar post-viral fatigue contexts. Prefer it over the sibling 561-group-hr-threshold endpoint when you want the full multi-metric analyzePacing report rather than just the isolated Workwell Foundation threshold calculation.
Side effects
- Insufficient biometric observations provided — too few data points to compute a meaningful rolling baseline
- Missing or malformed morning heart rate fields causing deviation computation to fail
- Heart rate values outside plausible physiological ranges rejected as invalid input
- Payment not completed or underfunded resulting in 402 response before analysis runs
- Schema validation error if required observation fields are absent or incorrectly typed
