Fetched live from IANA's RDAP bootstrap + the TLD registry's own RDAP server, and this server's own DNS resolver (no third-party DoH relay).… | - | $0.012 | listed | |

| d21 email_validate 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. Never opens an SMTP connection to the mailbox or confirms one specific inbox exists. Body { email }… | - | $0.006 | listed | |

Only the sections implied by the body actually run, in… | - | $0.05 | listed | |
| d21 news_search News Search ($0.009): multi-language, multi-country news headline search plus an optional volume/tone timeline, built entirely on the GDELT Project's free, keyless DOC 2.0 API (100+ languages, updated every 15min).

Fetched live from Base's public RPC +… | - | $0.03 | listed | |
| d21 weather Weather ($0.004): current conditions + short forecast, worldwide. 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.

Returns the stored item with its box id, which free GET /box/{box}/{key} reads need. | - | $0.002 | listed | |
| deadchannel Use before paying an x402 endpoint you have not used before, when you cannot tell a working seller from a trap, a testnet address dressed as mainnet, or a listing whose price no longer matches its challenge. Returns a verdict — live, degraded, trap, testnet or dead — a 0-100 risk score, and the specific findings behind both, so an agent can decline a bad endpoint instead of learning about it by losing the money. Costs less than the smallest payment it protects. | - | $0.005 | listed | |
| deal-radar-x402 Recent SEC Form D private-placement filings parsed into scored leads (0-100 with reasons): issuer, website and domain when EDGAR has one, industry, related persons and roles, offering amount, amount sold, amount remaining, investor count, use of proceeds, placement agent / broker-dealer with CRD, fund vs operating company, and the sec.gov filing link. Missing values are null. Up to 25 leads per call. Optional date-range backfill of up to 31 days. | - | $15,000.00 | listed | |

| depin-network Network health and token-economics verdict for a DePIN network from public data. Give network (helium) and get coverage size (IOT and MOBILE node counts), token supply for HNT, IOT, MOBILE and DC read on-chain, the emission and halving context, and a coverage-scale indicator. Each value is cited to its source. | - | $0.02 | listed | |
| depin-rewards Reward economics and earnings trend for a DePIN entity or subnetwork. Give network (helium) with an entity key or a subnetwork (iot, mobile). This is a keyed enrichment: without the Relay key configured it returns available false with a note; the keyless network, hotspot and wallet routes do not need it. | - | $0.02 | listed | |
| derivs-basis Perpetual basis for an asset: the mark-versus-oracle premium on venues that publish a native mark price (Hyperliquid), in basis points, with a naive annualized carry proxy. Shows how far the perpetual trades from the underlying oracle — a froth and leverage-cost signal. | - | $0.008 | listed | |
| derivs-funding Perpetual-swap funding rates for an asset fused across decentralized venues (Hyperliquid, dYdX v4): each venue's current funding plus an open-interest weighted aggregate funding rate, annualized APR, the cross-venue spread and dispersion.

| derivs-oi Open interest for a perpetual asset across decentralized venues (Hyperliquid, dYdX v4): per-venue open interest in coins and in USD notional (via each venue's mark or oracle price), the total aggregate USD open interest and each venue's share. One call, normalized across protocols. | - | $0.01 | listed | |
