Crypto News ($0.001 -- matches the category-leading incumbent's price exactly): fixed, no-required-params crypto headline feed -- a drop-in-shaped alternative to the category leader (GET, headlines[] with title/url/source/publishedAt; also mirrors its {status, data:{headlines[] with rank/whyItMatters/match, report}, meta} nesting field-for-field, as an additive alias). Built on this origin's own n

Gas Price ($0.002): current Base gas market read live from Base's own public JSON-RPC, not a hosted gas-oracle vendor -- legacy gas price (eth_gasPrice), EIP-1559 base fee (latest block), and a suggested priority/max fee (eth_maxPriorityFeePerGas + a computed 2x-base-fee heuristic), all in gwei, plus a plain-transfer cost estimate. Base mainnet only. Body {} or { chain: "base" }. Check free /v1/ga

Token Price ($0.003): Base token price derived from on-chain state, not a resold price-API feed. Curated majors (ETH, WETH, USDC, DAI, cbETH, cbBTC, BTC) are priced from Chainlink's own Data Feed aggregator contracts on Base; any other Base ERC-20 address is priced from its deepest discoverable Uniswap V3 pool against USDC (with a liquidity read and a low-liquidity flag), or a clean unsupported-to

United States coordinates (or a resolvable U.S. street address) read live from the National Weather Service's own public API (api.weather.gov), U.S. government data, plus active alerts.

Email Validate ($0.006): syntax + live MX/A-fallback deliverability + disposable-domain + role-address + free-webmail-provider + SPF/DMARC, with no third-party validation vendor at all -- syntax is RFC 5321/5322 grammar, MX/A/SPF/DMARC are live DNS via this server's own resolver (the same protocol-level sourcing as domain_intel), and disposable-domain detection is a static self-maintained list. Ne

Address Geocode ($0.008 — below the category-leading "geocoding" comparable's $0.01): forward + reverse U.S. geocoding in one route, built entirely on the U.S. Census Bureau's free, keyless Geocoder API (a federal government service, not a resold third-party product). Accepts `q` as an alias for `address` (the leading comparable's exact param name), and every response carries an additive `count`/`

Company Lookup ($0.01): normalized company-identity record from a name, ticker, LEI, or CIK — legal name, LEI, CIK (if SEC-registered), tickers/exchanges, jurisdiction, legal address, entity/registration status, and direct/ultimate parent.

Fetched live from IANA's RDAP bootstrap + th

SEC EDGAR Full-Text Search ($0.02): search the actual TEXT of SEC filings since 2001, across any company, by phrase — not just per-company metadata.
