Alerting: 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.
Audit trail: a verifiable, timestamped log of past oracle attestations (?limit=, default 20). Each entry carries its own signature from the verify-tx endpoint; the returned page is also freshly signed…
Batch 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 heteroge…
Bundle/all-access pass: one payment unlocks 2 minutes of free access to /api/bundle/market-snapshot, /api/bundle/normalized-gas, and /api/bundle/gas-metrics — instead of paying each separately (?subsc…
Enrichment: attaches real on-chain context to a bare address (contract vs EOA, native balance, transaction count, new-vs-active classification) — checkable facts only, no unverifiable labels.
Escrow-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-…
Freshness-tiered pricing: gas price + ETH/USD price, same data either way. ?freshness=cached ($0.002) serves the last known values with no network call; ?freshness=live ($0.02) forces a guaranteed-cur…
Cross-chain gas comparator: real, current gas price on Ethereum and Base side by side, with the delta and ratio between them, plus the estimated USD cost of a standard 21,000-gas transfer on each chai…
Historical 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,…
Derived 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 …
Insured 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…
Machine-to-machine invoicing: issue a signed invoice now (payerAddress, amountUsdc, optional lineItems/memo/dueBy); the payer settles it later at its own dynamically-priced /pay sub-resource, instead …
Filtering: 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 deliver…
Leaderboard: 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.
Aggregated market snapshot: Ethereum mainnet gas price (Gwei), ETH/USD spot price, and the latest Base mainnet block number and timestamp — combined into one call. Optional ?ref=<address> pays that wa…
Normalization: Ethereum and Base both return gas price and block data as raw hex (wei, Unix seconds) with no shared shape. This cleans both into one consistent schema per chain — decimal Gwei, ISO 860…
Reliability: ETH/USD price with retry-with-backoff and last-known-good cache fallback layered on top — sells dependability, not the raw data itself. Optional ?simulateFailureRate=0-1 for demoing the f…
Reputation 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 thi…
Task-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…
Register a subscription (yours or one you manage for another agent) for renewal-reminder tracking. Bookkeeping only — no auto-renewal, no custody, this server never pays on your behalf. Fires a webhoo…
Oracle: checks whether a base transaction hash has confirmed on-chain, and returns a signed (EIP-191) yes/no attestation — verifiable independently against 0x5a6d60f11C0E33f97E2De12b8B2b70d1B1FE9Efc, …
Multi-source oracle: checks a Base tx hash against 3 independent RPC providers in parallel and only signs an attestation if all of them unanimously agree. If they disagree, the raw per-source breakdow…
Format 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.
