data-retrieval-and-decoding

Validate up to 25 Brazilian CPF tax IDs in a single call. Cheaper per-item than individual requests — built for bulk/KYB workflows.

IP geolocation via ipwho.is. Returns country, region, city, lat/lon, timezone, ASN, ISP. Pass empty string to geolocate caller IP.

Volume of matching headlines over time (hour/day buckets) plus average sentiment per bucket with its provenance (GDELT document tone vs local lexicon, never a silent null) — a local sentiment timeline over the retained multi-day archive

Time-weighted average price (1h/24h) per venue pair, computed from our own 1-minute observation buckets. Includes coverage_pct and method notes for verifiability. Descriptive statistics only; not investment advice.

Fetch a public RSS or Atom feed with private-network blocking and return bounded current entries.

Pulls the current day's featured astronomy image along with its title and full explanatory caption, as structured JSON. Built for content agents, daily digest bots, and education tools that want a rotating supply of space imagery with context attached rather than a static image library. Cached 6 hours.

Random number API with proof: an integer in your range plus the HMAC-SHA256 server seed revealed so the draw is verifiable after the fact. Provably fair randomness for games, raffles, and tie-breaking agents.

Financial math API: compound interest with any compounding frequency, monthly loan/mortgage payment and total interest, or ROI. Exact, deterministic.

Call DefiLlama TVL/yields through our metered gateway: our rate-limit budget and a 300s cache absorb your polling, so your loop never sees a 429. Inputs: path (upstream path, e.g. /ping) and q (raw query string). Returns the upstream JSON under 'data'.

Bulk historical window (up to 24h) of 1-minute DEX spread statistics for a given pair, in one call. Useful for slippage calibration and backtesting. Descriptive statistics only; not investment advice.

[3-LEG] Hurricane chain, one basin (?entity=atlantic|epacific|cpacific): leading NHC official 2-day and 7-day genesis probability, QUOTED from NHC, never our forecast -> current active storms - category, wind, pressure, position -> realized official watches, warnings, landfall (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: NOAA NHC. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

[3-LEG] Severe convection and hail chain, one convective region (?entity=tornado-alley-core): leading SPC Day-1 outlook with CAPE, CIN and shear - hours of lead -> current current storm reports -> realized realized hail and wind damage reports (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: NOAA SPC. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

Draws a random integer within any min-max range using HMAC-SHA256 over a client-supplied seed, revealing the server seed so the draw can be independently recomputed and verified afterward. For raffles, matchmaking, tie-breaking between competing agents, and any process where 'trust me, it was random' isn't good enough.

[TIME SERIES EXPORT] Full retained series for one signal and entity (?days=, ?format=json or csv): every snapshot up to days (default 400, cap 1000) with snapshot_date, observed_at, data_age_hours, current, band and record_hash. For research, actuarial and base-rate work. Free 7-snapshot shape preview at /gauge/history-preview. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.

[BATCH+PROOF] All entities for one signal at their latest reading, with band, frequency_label and percentile columns so you can rank across stations and screen for the unusual in one call. Cross-station comparison is the point: one river gauge alone tells you little, 200 of them ranked by distance-to-action tells you a lot. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.

Decode a 3-character World Manufacturer Identifier or 6-character low-volume identifier through the official NHTSA vPIC API.

Execute one bounded eth_call against Base, Ethereum, or Arbitrum and return raw deterministic call data without signing or broadcasting.

Extract pages from a PDF by range (e.g. 1-3,7) into a new PDF. Deterministic, 0.002/call.

Turn a 4-byte function selector or full calldata into its human-readable function signature, and (when calldata is present) the decoded argument values. Supply an `abi` for a fully deterministic offline decode, or omit it to look the selector up in public signature registries. Reads with automatic fallback.

Compute the level monthly payment, total paid and total interest of a fully-amortizing loan. Handles a 0% rate. Set schedule=true to also return the full month-by-month amortization table.
