Today we're opening up the CrypTok Public API — the same multi-chain data engine that powers the charts, feeds, and indexers across CrypTok, now available as a single, normalized REST surface you can build on.

One key. One base URL. Dozens of upstream blockchain data providers — Solana, Ethereum and its L2s, Bitcoin, NFT marketplaces, DeFi protocols, lending markets, and yields — collapsed into clean, predictable JSON.

What you can pull

• Market & price data — live prices, OHLCV candles, market caps, trending coins, indexed tokens and trades.
• DeFi — protocol catalogue, TVL, yields, lending markets, bridges, stablecoin pegs, and liquidity pools (including freshly-launched ones).
• On-chain (Solana / EVM / Bitcoin) — swap quotes, a sub-second live swap feed, per-mint transfer ledgers, holder distribution, and Bitcoin chain pulse.
• Signals — a combined token risk score, native social-graph signal, and aggregated crypto news.
• Platform — CrypTok indexer stats, anonymized platform metrics, and the ability to publish a post as your key owner.

Authenticate

Every request takes your API key in any one of three ways — use whichever fits your stack:

X-API-Key: YOUR_KEY
Authorization: Bearer YOUR_KEY
?api_key=YOUR_KEY

Your first call

Grab the top 10 trending coins and pools:

curl -H "X-API-Key: YOUR_KEY" \
  "https://cryptok.me/api/v1/trending?limit=10"

Or a Solana swap quote:

curl -H "X-API-Key: YOUR_KEY" \
  "https://cryptok.me/api/v1/quote?inputMint=So11111111111111111111111111111111111111112&outputMint=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v&amount=1000000000"

Responses are plain JSON — success returns the data directly; errors return an error field with an HTTP status code.

Plans

Request access from your account, tell us what you're building, and we approve within 24 hours. Tiers scale your rate and daily limits:

Tier	Who it's for
Free	Hobby projects, prototypes, and evaluation.
Pro	Production apps — higher limits, plus AI chat access.
Enterprise	High-volume and commercial workloads.

Pay as you go with x402

No subscription? Pay per call. The API speaks the x402 protocol over USDC on Solana: deposit USDC to the treasury, redeem it into a prepaid spend-token, and each request burns one credit. Hit GET /api/v1/x402/info for the machine-readable payment details — ideal for autonomous agents that pay their own way.

Start building

Browse the full, interactive reference (every endpoint, parameter, and a live “try it” console) at cryptok.me/developers/reference, and request your key from cryptok.me/developers.

We're just getting started — more endpoints, deeper history, and richer signals are on the way. Build something great, and tell us what you ship.

Now: act as your own account

Beyond data, the API now includes a full account layer. With a write-scoped key, your app or AI agent can read your home feed, mentions, and notifications, and post, comment, and react as your own account — all through the same guarded path as the web app. See the API reference for the /api/v1/me, /feed, /posts, /comments, and /reactions endpoints.
