All services

Look up public holidays for any country and year, check whether a specific date is a holiday, and calculate the next business day — so agents can handle scheduling, SLA calculations, deadline setting, and date-aware workflows without hardcoding country-specific holiday rules.

Compatibility alias for the top stressed crypto issuers route.

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

Material-change feed for up to 5 crypto assets. Pass the cursor from your last call and receive ONLY what changed since: funding sign or band, funding trend, open-interest regime, alert set, and source stale/recovered. Returns an explicit no-change packet rather than pretending, plus per-asset freshness and a next-poll time derived from the real 5-minute collection cadence. Market data, not advice. $0.02 USDC via x402.

Coinbase price premium vs composite spot median (OKX + Kraken + Binance). premium_pct = (coinbase / composite_median − 1) × 100. Positive = US/institutional demand skew; negative = global selling pressure. Covers BTC/ETH/SOL/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/BCH/ATOM/NEAR (assets listed on Coinbase). Point-in-time only — no historical baseline stored. $0.02 USDC per call via x402.

Real-time crypto derivatives signals for BTC/ETH/SOL/BNB/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/TRX/BCH/ATOM/NEAR/APT-USD: perpetual futures funding rate (raw + annualized), next_funding_time, funding_interval_hours, open interest and 1h change, basis (perp vs index), funding-rate trend. Live data from Bybit/OKX via Kronos market_signals. Pay-per-call via x402.

Structured market digest for any of the 16 supported crypto assets. Deterministic composite from live signals: derivatives (funding, basis, OI), market regime, 30d realized volatility, fear-greed index, and ML forecast probability (BTC/ETH/SOL only). Single-call 'start here' bundle for autonomous agents. $0.02 USDC via x402.

Fact verification — returns verdict, confidence, current truth

Returns a list of email inboxes or mailbox accounts.

Real-time or 15-min delayed stock quote and share price for any US equity ticker — current price, open/high/low/close (OHLC), previous close, and percent change as JSON. Covers NYSE, NASDAQ, AMEX (8,400+ stocks and ETFs). No API key required. Use for: stock price lookup, equity quote, share price check, portfolio valuation, trading signals. $0.003 USDC delayed / $0.01 real-time (add ?tier=realtime).

US inflation calculator — cumulative CPI inflation between any two years, e.g. what $100 in 1990 is worth today (?from=1990&to=2026&amount=100). Returns cumulative inflation % and the inflation-adjusted value as JSON, from official CPI data via FRED (Federal Reserve). Use for: purchasing power comparison, real vs nominal value, historical price adjustment, cost-of-living calculation. $0.003 USDC per call.

Jupiter v6 swap quote on Solana — price, route, slippage. Solana-native.

Discover RTP robots. Filter by capability, chain, price, status.

Call OpenAI's gpt-4.1-mini via a single pay-per-call x402 endpoint — no OpenAI account or API key needed, pay $0.02 per request in USDC. Standard OpenAI chat.completions request/response shape, capped input and output. Search terms: OpenAI, gpt-4.1-mini, chat completion, LLM, no API key.

Validate data against a supplied schema — checks required fields, nested objects, arrays, enums, string formats, numeric ranges, lengths, and additional-property rules deterministically, with optional type coercion and repair, returning precise errors with JSON paths so agents can verify structured data before acting on it.

Repair malformed JSON into valid JSON — fixes code fences, trailing commas, single quotes, unquoted keys, bad escapes, duplicate keys, truncation, and JSON buried in prose. A deterministic tokenizer runs first (no LLM cost), with an optional Haiku fallback, plus optional schema validation and type coercion — so agents can rescue broken model output or dirty data in one call.

Cheap, fast "is this a dateable event?" filter for social and web text — one tiny Haiku call returns is_event, confidence, and a one-line reason, so agents can screen every post for free-ish and only pay for full extraction on the ones that pass. Front-end filter to /event-extract; intentionally minimal output for cost/latency discipline.

USD Coin

Complete DeFi portfolio snapshot for any wallet address in one call. Aggregates wallet balance and token holdings (Viem + Blockscout), on-chain risk score and flags, top USDC DeFi yields available on the chain (DefiLlama), and current gas prices — all fetched in parallel.

DNSSEC health check: reports whether a domain is DNSSEC-signed (DNSKEY), has a DS record at the parent, and whether the resolver authenticated the answer, with advisory warnings.

WHOIS domain lookup — the raw WHOIS record from the authoritative registry (registrar, nameservers, and creation / expiry / updated dates and status) returned as text with the responding server, for domain due-diligence, expiry monitoring and ownership research. See /dns/rdap for a parsed, structured alternative.
