The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain.

Divide by 1e18 to get token amounts.

Fee estimate for ANY target block (1-1008) — flat $0.001 per call, USDC on Base, no signup.

Subscribe for 30 days to the change feed behind /crypto/scan: one cursor over the upstream advice ledger, all coins at once. Returns a handle and a cursor; polling is then free and unlimited: /crypto/feed/since returns every published change since your cursor — new signals, classification flips, status changes (PUBLISHED/STALE/INVALIDATED), score and entry-zone changes. Be first to know when the market state flips; the full advice per signal stays a separate paid call.

Fetch any RSS or Atom feed and get normalized JSON items — title, link, ISO-8601 date, plain-text summary, author, categories. Point it at a regular HTML page and it auto-discovers the feed. RSS 2.0, RSS 1.0/RDF and Atom, messy real-world feeds included. The monitoring primitive for agents that watch sources.

Call when an agent needs an RSS/Atom feed parsed into title plus up to 50 items (link, published, summary). SSRF-safe. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/feed-parse first.

What paying buyers said about each tool on this server: good and bad counts and the number of distinct wallets behind them, over a window you choose. Every verdict counted here was written by the wallet that paid for that specific call, one per settlement transaction, so the numbers cannot be inflated by anyone who did not buy. Counts only - no payer addresses and no review text, ever. Bad counts are published beside good ones, including ours.

FEMA NFIP flood-insurance claims for a county. Perfect for: 'NFIP claims for a county', 'flood insurance paid claims history', 'FEMA flood loss data for an area', 'flood claim totals for a place'. Returns OpenFEMA NFIP redacted claim history aggregated to the county: total claim count, total paid, year range, and top rated flood zones by claim count. National, no key. County aggregates only, no PII. Historical fact, not a prediction. Charge-free when the lookup fails.

For each field cell, subtracts measured available nutrient from a supplied target and divides positive deficits by an explicit recovery fraction. It reports per-hectare rates and area totals. It does not infer crop targets, validate laboratory samples, account for nutrient chemistry or constitute an agronomic application prescription.

🆕 Prices the same fiat purchase across EVERY payment method a country allows, and ranks them by what the buyer actually receives. On $100 in the US the spread is real: card takes 2.44, bank transfer 0.50, a funded fiat wallet nothing. Returns each rail's fee, net amount, min/max limits, and the cheapest one. Live Coinbase pricing, not a rate card. Pass address= for a payable checkout link. Not financial advice.

🆕 The feasibility check before you ask a user for money: which fiat-in and cash-out rails Coinbase actually runs in a country, the currencies and min/max limits for each, and how many assets across which networks. Distinguishes a country with card rails from one where crypto can only be transferred in — a difference most integrations discover only after a user fails. 122 countries covered.
