  description: "Surf data API gateway providing typed endpoints for crypto market data, project analytics, social signals, on-chain queries, and more. All endpoints use credit-based billing with per-request rate limiting.\n\n## Parameter Naming Conventions\n\nAll endpoints follow a standardized naming scheme. Use these canonical names when calling the API.\n\n### Asset Identification\n\n| Param | Type | Description | Example |\n|-------|------|-------------|---------|\n| `symbol` | string | Uppercase ticker symbol(s), comma-separated | `BTC`, `ETH,SOL` |\n| `q` | string | Free-text search keyword | `bitcoin` |\n| `id` | string | Surf entity UUID for direct lookup | `550e8400-...` |\n| `address` | string | On-chain contract or wallet address. Also accepts ENS names (e.g. `vitalik.eth`) which resolve automatically. | `0xdead...`, `vitalik.eth` |\n\n### Time & Aggregation\n\n| Param | Type | Description | Example |\n|-------|------|-------------|---------|\n| `time_range` | string or int | Lookback window | `7d`, `30d`, `365d`, `max` |\n| `interval` | string | Candlestick / indicator interval | `1h`, `1d`, `1w` |\n| `granularity` | string | Data aggregation granularity | `day`, `block`, `hour` |\n\n### Filtering & Sorting\n\n| Param | Type | Description | Example |\n|-------|------|-------------|---------|\n| `chain` | string | Blockchain name (canonical long-form only) | `ethereum`, `solana`, `base` |\n| `currency` | string | Quote currency | `usd`, `eur`, `btc` |\n| `metric` | string | Metric name (endpoint-specific enum) | `nupl`, `tvl` |\n| `type` | string | Category selector (endpoint-specific enum) | `us-btc-spot` |\n| `sort` | string | Sort direction | `asc`, `desc` |\n\n### Pagination\n\nAll list endpoints support:\n- `limit` (int, default: 20, max: 100) — results per page\n- `offset` (int, default: 0) — pagination offset\n\n### Supported Chains\n\nUse canonical long-form names only. Short aliases (eth, sol, matic, etc.) are **not accepted**.\n\n| Chain | Value |\n|-------|-------|\n| Ethereum | `ethereum` |\n| Polygon | `polygon` |\n| BNB Chain | `bsc` |\n| Solana | `solana` |\n| Avalanche | `avalanche` |\n| Arbitrum | `arbitrum` |\n| Optimism | `optimism` |\n| Fantom | `fantom` |\n| Base | `base` |\n| Linea | `linea` |\n| Cyber | `cyber` |\n\nNot all chains are available on every endpoint. Check each endpoint's `chain` enum for supported values.\n\n## Authentication\n\nAll data endpoints require a Bearer token in the `Authorization` header:\n\n```\nAuthorization: Bearer <API_KEY>\n```\n\n## Error Responses\n\nAll endpoints return errors in a consistent format:\n\n```json\n{\n  \"error\": {\n    \"code\": \"FORBIDDEN\",\n    \"message\": \"insufficient credits\"\n  }\n}\n```\n\n| HTTP Status | Meaning |\n|-------------|---------|\n| `400` | Bad request — invalid or missing parameters |\n| `401` | Unauthorized — missing or invalid API key |\n| `404` | Not found — the requested entity does not exist |\n| `422` | Validation error — parameter value is out of range or invalid |\n| `429` | Rate limited — too many requests, retry after the indicated interval |\n| `502` | Upstream error — a data source is temporarily unavailable |\n\n## Credits\n\nEach API call costs a certain number of credits. The cost is returned in every response under `meta.credits_used`. Check your remaining balance via `GET /v1/me/credit-balance`.\n"
