Professional market data API for crypto derivatives, spot markets, prediction markets, Hyperliquid HyperCore data, proprietary volatility surfaces, and analytics.
## Authentication
Use an API key for authenticated REST requests:
```http
X-API-Key: your-api-key-here
```
Most data endpoints also support x402 pay-per-request without an API key.
| Resource | Path |
| --- | --- |
| OpenAPI JSON | `GET /openapi.json` |
| x402 discovery | `GET /.well-known/x402` |
| Changelog | `GET /api/v1/changelog` |
| WebSocket docs | `GET /websocket` |
## REST Surfaces
| Surface | Examples |
| --- | --- |
| Instruments | Cross-market contract reference data |
| Futures | OHLCVT, trades, tickers, orderbook, liquidations, carry |
| Perpetuals | OHLCVT, trades, funding, open interest, orderbook, liquidations |
| Options | OHLCVT, trades, Greeks, volatility, flow, dealer GEX |
| Vol Surface | Proprietary surface snapshots, slices, strikes, term structure, risk |
| Spot | OHLCVT, ticker, trades, volume, L2 orderbook, snapshots |
| Predictions | Polymarket instruments, categories, trades, ticker history |
| Hyperliquid - HyperCore | Node-derived fills, liquidations, positions, funding, TWAPs, resting orders, L2 books |
| Analytics | Realized volatility and derived metrics |
## Pagination
Paginated endpoints return the cursor at `meta.next_cursor`. Pass that value back as the `cursor` query parameter to fetch the next page.
## WebSocket Streaming
Real-time streams are documented at `/websocket`.
| Data | Channel pattern |
| --- | --- |
| Trades | `trades.{market}.{exchange}.{instrument}` |
| OHLC ticker | `ohlc.ticker.{market}.{exchange}.{instrument}.{timeframe}` |
| OHLCVT | `ohlc.vt.{market}.{exchange}.{instrument}.{timeframe}` |
Variables: `market` is one of `perpetuals`, `futures`, `options`, or `spot`; `timeframe` is one of `1m`, `5m`, `15m`, `1h`, `4h`, or `1d`.
## Quick Start
```bash
curl "https://apiv2.laevitas.ch/api/v1/futures/ohlcvt?exchange=deribit&instrument_name=BTC-PERPETUAL" \

Cryptographically attested, first-party data feeds for AI agents — covering crypto markets, DeFi yields, weather, earthquakes, news, code-pulse, threat-intel, address reputation, sanctions screening, and supply-chain verdicts. Every paid response carries EIP-712 receipts you verify before acting: (1) a GATEWAY delivery-integrity receipt (X-BYTE-Attestation header, signed by the PayPerByte gateway key) proving these are exactly the bytes we served; and (2) on the 14 attested feeds (provenance:eip712-attested in GET /feeds), a LIVE per-feed PayloadAttestation by that feed's OWN distinct publisher key, anchored ON-CHAIN — recover it from the broadcast the response references via txHash. (Separately, the POST verdict oracles embed their own per-feed `attestation` directly in the response body — recover attestation.signer.) Both attest authenticity + tamper-evidence under the BYTE Library domain. NEITHER asserts the correctness of the underlying data or any verdict, and NEITHER claims an independent third-party data source signed it — all keys are first-party PayPerByte. Pay per call in USDC over x402 with no API keys — a wallet, not a secret on the box. Settlement is on Base (eip155:8453).

Starts at $0.001 for short base-voice speech and $0.005 for Custom persona voices, with no API keys, subscriptions, dashboards, or monthly commitments. Built for autonomous agents that need to speak inside Discord, Telegram, browsers, games, monitoring workflows, support flows, and content pipelines.
Use the OpenAI-shaped `/v1/audio/speech` endpoint when you want a familiar request format for the 10 base voices, or use `/v1/tts/custom` for Custom-only persona voices like Storyteller, Velvet, Narrator, Announcer, Assistant, and Urgent. Pro adds speed and quality controls for base voices. Custom unlocks persona voices plus speed and quality controls.
Expression controls: `speed` is available on Pro and Custom routes from 0.7-2.0 with presets slow=0.7, normal=1.0, fast=1.3, rapid=1.6. `steps` controls quality from 1-100 with presets draft=4, standard=8, high=16, ultra=24. Persona voices are prebuilt expressive blends and require Custom tier.
A micropayment-priced alternative to API-key TTS services like OpenAI TTS, ElevenLabs, Cartesia, and PlayHT.
