  81. 100lab.paidapis.net/api/batch-resizeBatch task-runner: run up to 5 image-resize jobs in one paid call (?jobs=<JSON array of {url,width,height}>). Priced as the sum of each job's real output-megapixel cost — one payment covers N heterogeneous units of work instead of paying per call for each.$0.005 Base256 ms1 payers100% up
  82. 100lab.paidapis.net/api/gas-history-exportHistorical data export: raw Ethereum gas price samples over a date range (?from=, ?to=, ISO 8601, max 24h; ?format=json|csv). Priced at $0.0005/sample (min $0.005) — the real row count for your range, not a flat fee.$0.005 Base280 ms1 payers100% up
  83. 100lab.paidapis.net/api/reputationReputation layer: a trust score (?address=) computed from two real sources — live on-chain activity (via enrichment) and our own ledger of settled payments this address has actually made to us. No third-party data, fully documented breakdown, not a black box.$0.01 Base299 ms1 payers100% up
  84. 100lab.paidapis.net/api/insured-feed/subscribeInsured data feed: pay a premium for an ETH/USD price snapshot (?premiumUsdc=, ?maxDeviationPct=, ?checkDelaySeconds=). If the real price has drifted more than your insured tolerance by the checkpoint, claim a 2x refund — a real payout for genuinely stale data, not a fabricated failure.$0.01 Base299 ms1 payers100% up
  85. 100lab.paidapis.net/api/leaderboard/listLeaderboard: pay a tiny fee to appear on a ranked scoreboard (?name=, ?url=, ?note=). No underlying data product — pure visibility. Ranked by cumulative amount paid; paying again bumps your rank.$0.005 Base281 ms1 payers100% up
  86. 100lab.paidapis.net/api/resize-imageTask-runner: resize an image (?url=, ?width=, ?height=, max 2000px each) and return it as a data URL. Priced at $0.02/output-megapixel (min $0.005) — sells compute, metered by resource use, not a flat fee.$0.005 Base271 ms1 payers100% up
  87. 100lab.paidapis.net/api/escrow/createEscrow-lite: payment settles immediately, like every other endpoint here — but the purchased resource is withheld until our oracle confirms your named release condition (a given tx hash confirming on-chain). Soft escrow: delayed delivery, not real fund custody.$0.02 Base292 ms1 payers100% up
  88. 100lab.paidapis.net/api/alerts/subscribeAlerting: register a one-shot webhook that fires when Ethereum gas price crosses your threshold — the server pushes to you when it happens, instead of you polling for it.$0.02 Base280 ms1 payers100% up
  89. 100lab.paidapis.net/api/wiki-summaryFormat conversion: Wikipedia's own REST API serves full rendered HTML, not JSON. This fetches an article's lead section (?title=) and returns clean, tag-free paragraph text as JSON.$0.01 Base290 ms1 payers100% up
  90. 100lab.paidapis.net/api/large-usdc-transfersFiltering: USDC on Base settles thousands of transfers a minute. This scans the raw feed and returns only transfers above a value threshold (?minUsd=, default $10,000) — the noise removed, not delivered.$0.02 Base267 ms1 payers100% up
  91. 100lab.paidapis.net/api/gas-metricsDerived metrics: Ethereum gas price sampled continuously in the background and turned into rolling average, min/max, volatility, and trend direction over a window (?windowMinutes=, default 10) — none of which exist in the raw upstream feed's single instantaneous value.$0.01 Base268 ms1 payers100% up
  92. 100x402.swaphunt.dev/v1/fomo/green-candles-streakCounts consecutive green candles on the chosen interval and returns the historical outcome stats after streaks of that length (mean-reversion odds). Use to gauge exhaustion risk before buying a long green run.$0.003 Base167 ms1 payers100% up
  93. 100x402.swaphunt.dev/v1/fomo/already-extendedIs price over-extended? Distance from MA20/MA50, Bollinger-band position and a z-score in one read. Use to avoid entering after price has stretched far from its mean. Mean-reversion context.$0.003 Base181 ms1 payers100% up
  94. 100graphadvocate.com/uniswap/pretradeUniswap pre-trade due-diligence. POST {token, chain?, version?}.
