How this service works
Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.
Output
Returns a structured JSON payload containing a calibration_decision (go/no-go signal), priority_queue of actionable markets, risk_breakdown, review_queue, avoid_queue, signal_buckets, label_balance, bucket_counts, sample_rows of recent resolved markets, a btc15_buyer_playbook, purchase_acceptance status, quality_summary, and source metadata — giving an agent or risk tool a complete picture of current BTC 15-min prediction market signal quality.
Example use cases
Pre-trade market quality check
“Before I put any money into BTC 15-minute up/down markets, scan the last 96 resolved markets and give me the calibration decision and risk breakdown so I know if the signal quality is good enough to act on.”
Autonomous agent market participation gate
“Run the BTC 15-min calibration slice with limit 200 and remaining_seconds_max 90, and tell me whether the priority queue shows any markets worth entering right now based on the buyer playbook and purchase_acceptance status.”
Risk tool signal bucket audit
“I need to audit the signal buckets and label balance across the last 48 resolved Bitcoin 15-minute markets — pull the calibration slice with 48 sample rows so I can review the bucket counts and quality summary for our risk report.”
Technical details
Endpoint
GEThttps://x402.xx402.icu/api/btc15-calibration-slice?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or risk tool needs to evaluate the calibration quality of Bitcoin 15-minute Up/Down prediction markets before committing capital — specifically when you want bucketed signal analysis, a go/no-go calibration decision, and a buyer playbook in a single call. Prefer this over generic price feeds when the decision to participate in a short-term BTC prediction market depends on historical signal reliability rather than raw price data.
Side effects
- Payment not provided or invalid x402 payment header — returns 402 Payment Required
- limit parameter out of range (must be 24–240) — returns 400 Bad Request
- remaining_seconds_max below 15 or above 180 — returns 400 Bad Request
- Upstream market data unavailable — source_status may indicate degraded or empty results
- Stale data if no markets have resolved recently — empty priority_queue and sample_rows
