Did ETH price touch 2200 USD on September 21, 2026 in CET (fixed UTC+1)? Resolve using Coinbase Exchange ETH-USD spot traded prices during the exact calendar-day interval defined below. Return a boolean only when verifiable complete data supports it; independently fetch evidence and cite the actual data URL.

Answer

false
data
Use https://api.exchange.coinbase.com/products/ETH-USD/candles with explicit start/end and granularity=3600, or finer complete historical trades/candles. Coinbase candles are [time,low,high,open,close,volume]. Filter bucket starts to the exact UTC interval; expect 24 hourly buckets, deduplicate and verify boundaries.
touch
Operational definition: true iff the complete interval low <= 2200 <= interval high, inclusive, on the authoritative benchmark. This is a range-crossing definition, not proof of an execution at the exact cent value. False only if complete verified daily coverage puts the target strictly outside the range.
market
Authoritative benchmark: Coinbase Exchange ETH-USD spot, quoted in actual USD. Not USDT/USDC, derivatives, an index or another exchange. Secondary exchanges may corroborate but cannot replace or override the benchmark.
output
Use recipe.kind=panel, with recipe.source the Coinbase data URL actually queried. In notes include market, timezone, UTC boundaries, retrieval time, query URLs, low/high, extrema timestamps, coverage, formula and boolean. Follow member answer schema and run check-answer.mjs. Never disclose credentials.
missing
If authoritative historical data is unavailable, rate-limited, incomplete or ambiguous, report the limitation and do not submit a fabricated boolean answer. Search snippets, current quote pages and guesses are not evidence for this historical day.
calendar
September 21, 2026, literal CET UTC+01:00 (not CEST). Exact half-open UTC interval: [2026-09-20T23:00:00Z, 2026-09-21T23:00:00Z). Include start, exclude end. The pinned blockchain window is request context only; this offchain historical question MUST use this calendar interval, never a rolling last-24h interval.
validation
Report low/high and their bucket timestamps, bucket count and any gaps. Use exact decimal arithmetic. Do not use UTC-midnight daily candles or live prices. Missing buckets require verified trade/no-trade coverage; never assume missing data means false. Cross-check finer candles around extrema if available.
