Every agent-payable API.

Block header for a slot: blockhash, previous blockhash, blockTime, transaction count. Pass a slot number.

Number of non-zero token accounts for a mint and top holders via the indexed RPC. Holders + concentration are the classic rug signals.

Current slot number plus block height. Cheapest liveness probe for the network.

Fee breakdown for a transaction: base fee, compute units consumed, and compute-unit price if present.

Just the USD price and 24h change for a mint. The cheapest endpoint here — built for agent polling loops.

Every DEX pair for a mint across Solana venues, with price, liquidity and 24h/6h/1h volume. Raw pair enumeration for aggregators.

Live trending/new Solana DEX pairs by 24h volume. A fresh feed for agents, per call.

Recently created Solana DEX pairs with non-trivial liquidity — an early discovery feed for agents watching for fresh listings.

Status, slot, fee, block time and transfer summary for a Solana transaction signature. Live.

Summary of current and delinquent vote accounts: validator count, total activated stake, delinquency. Validator-health context in one call.

Minimal transaction status: found/not-found, success or error, slot, blockTime, fee. The cheapest tx lookup — for confirmation polling.

Everything about a token in one call: market data + supply + safety score + holders + liquidity + momentum. The full pre-trade dossier.

Live Solana cluster health: health, current slot, epoch, and SOL/USD price. Cheapest call.

Native SOL balance plus every SPL token balance (incl. USDC) for a Solana address. Live.

Total USD value of a wallet: SOL (live price) + every SPL token balance valued by DEX price. One call for a full portfolio valuation.

Directional momentum: 1h/6h/24h price change blended with volume trend, returning a signal (up/down/flat) and strength score.

Convert between unix epoch and human time: pass ?value=<seconds|ms|ISO-string> and get back epoch (s + ms), ISO-8601 UTC, and the value in a target timezone (?tz=America/Santiago, default UTC). Units are auto-detected (10-digit = seconds, 13-digit = ms).

Generate a QR code for any text/URL and return it as an inline SVG (and a base64 data URI). Query: ?text=<content> (required), size=<px per module, default 6> and margin=<modules, default 4>. Pure CPU, no external service.

Convert any value between units: length (m/km/mi/ft/in/yd/nmi, plus Russian verst/sazhen/arshin/vershok), mass (g/kg/lb/oz/tonne, plus Russian pood/funt/zolotnik), area (m2/ft2/km2/acre/hectare) and temperature (C/F/K). Pass ?value=<n>&from=<unit>&to=<unit>. Returns the converted value and the unit category.

Decode a JWT (JSON Web Token): returns the header, payload and the extracted claims (subject sub, issuer iss, audience aud, expiration exp with `expired` flag and seconds remaining, issued-at iat, not-before nbf, algorithm alg, key id kid). Decode-only — the signature is NOT verified, so claims are informational. Pass the token via ?token=<jwt> (query param, no length limit).

Compute a SHA-256 fingerprint of any string: full hex digest, colon-separated (like SSH fingerprints), a short 16-char id, and base64. Deterministic, CPU-only. Pass ?text=<content>.

A LIVE, sourced snapshot of x402 adoption across the public ecosystem: how many pay-per-call services are indexed, on which networks and assets, in which categories, and at what USD price points (min/median/mean/max). Aggregated live from 402index.io, the Coinbase CDP Bazaar and the PayAI Bazaar; every figure carries its source URL and a fetchedAt timestamp. No fabrication - down sources report null, never guessed.

5-minute strategies unlikely to be luck (advanced): 5-minute calls that beat at least 90% of the coin-flip strategies over 7d, ranked by return. Ready-made list, no settings: top 10 with full stats for every window from 5 minutes to 5 years (hit rate, return, win ratio, max drawdown, Sharpe, Calmar), runner-ups and current leaders. On-chain verified where covered, else simulated*. Past performance is no guide to the future; not advice.
