Crop-protection + input retail prices: Retail shelf prices and stock availability for crop-protection products, seeds and foliar feeds, read daily from East African agro-dealer catalogues — Kenya and Uganda today. Up to 100 rows per call, $0.10 USDC. Filters: source, country, category, product, formulation, pack_unit, brand.

Computes mean NDVI and an ordinary least-squares daily NDVI trend, then applies yield = intercept + mean_coefficient×mean_NDVI + trend_coefficient×daily_trend. It does not derive NDVI from imagery, account for crop stage or weather, or provide an agronomically calibrated forecast unless the caller supplies valid coefficients.

Cross-asset DECISION brief: ONE call gives an autonomous agent a trade-ready read across China and US equities, crypto and macro. Fuses macro regime + ETF allocation, crypto stance (BTC RL lean, perp funding/OI), equity reads with top setups (symbol + take-profit/stop-loss), China smart-money and leading sectors, the China social-pulse leading indicator and a one-line recommendation. Deterministic, no LLM. ?focus=all|china|us|crypto&market=A|US.

Dispatches cross-border payouts across Base, Solana, and Ethereum with optimized gas estimation and cryptographic batch transaction hashes.

Returns the outstanding cross-border positions of banks located in a reporting country against counterparties in another, from the BIS locational banking statistics, split into claims and liabilities and never netted silently. The separation matters: a jurisdiction showing large claims and large liabilities is intermediating, not lending, and reporting only a net figure hides the gross exposure that actually fails in a crisis.

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 chain (using the live ETH/USD price). No advice or 'cheaper chain' verdict — just the numbers.

Applies caller-supplied rename and numeric scale/offset rules to scalar attributes, optionally retaining unmapped fields, then hashes the canonical mapped payload. It does not transfer ownership, call a chain, validate either game, preserve semantics, or authorize asset use.
