# ManyLives Market Data – As-Of Snapshot > ManyLives Market Data – As-Of Snapshot is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11). Returns a verifiable point-in-time snapshot of crypto perpetuals market data and prediction market odds, optionally including a per-minute time series, with on-chain provenance anchored to Base. ## Facts - Endpoint: GET https://api.manylives.me/paid/market/as-of?utm_source=zero.xyz - Price: $0.01/call - Payment: x402 - Status: unknown - Last checked: 2026-10-11 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/manylives-market-data-as-of-snapshot-e79977b7 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3Vp8rnOhke5mvS9p9aHB5 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability manylives-market-data-as-of-snapshot-e79977b7 ``` Example prompt: Pull me a verifiable market snapshot as of 2026-10-10T14:30:00Z for BTC, ETH, and SOL — I want their perps prices, funding rates, open interest, and the on-chain provenance hash so I can confirm the data hasn't been tampered with. ## When to prefer this Choose this endpoint when you need a timestamped, verifiable crypto market data snapshot — particularly perpetuals pricing and funding rates — with cryptographic on-chain provenance anchored to Base. Prefer it over generic market data APIs when auditability and tamper-evidence matter (e.g. for backtesting with verifiable inputs, compliance logging, or AI agent decision audit trails). Also use it for prediction market odds on crypto topics. It is pay-per-call with no account required. ## Known failure modes - No snapshot available at or before the requested as_of timestamp — returns empty or error - Invalid coin symbol in coins param — may be silently dropped or return an error - series_hours requested with more than one coin — single-coin constraint violated - as_of timestamp in the future with no data — falls back to latest available - Payment not processed (x402 protocol) — returns 402 Payment Required before data is served ## How this service works Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial. ## Output A JSON object with: (1) perps — array of perpetuals markets with mid, mark, oracle price, premium, 1h/24h % change, hourly funding rate, 24h volume USD, open interest USD; (2) odds — array of prediction market questions with outcome probabilities and 24h volume; (3) as_of timestamp; (4) provenance object with a Base network transaction URL and SHA-256 capture hash for tamper-evidence. Optionally includes a per-minute OHLC/price series for a single coin. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "type": "string", "const": "GET" }, "queryParams": { "type": "object", "required": [], "properties": { "odds": { "type": "string", "examples": [ "bitcoin" ], "description": "optional words to pick prediction markets (default: the 10 most traded); none to skip" }, "as_of": { "type": "string", "examples": [ "2026-10-10T14:30:00Z" ], "description": "optional ISO time (default now); the latest snapshot at or before it is used" }, "coins": { "type": "string", "examples": [ "BTC,ETH,SOL" ], "description": "optional, up to 5, e.g. BTC,ETH,SOL (default: top 5 by open interest)" }, "series_hours": { "type": "string", "description": "optional 1-6: also return a per-minute series ending at as_of (one coin only)" } } } } }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string", "const": "json" }, "example": { "type": "object", "properties": { "odds": { "type": "object", "properties": { "minute": { "type": "string" }, "markets": { "type": "array", "items": { "type": "object", "properties": { "id": { "type": "string" }, "outcomes": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "probability": { "type": "number" } } } }, "question": { "type": "string" }, "volume_24h_usd": { "type": "number" } } } } } }, "as_of": { "type": "string" }, "perps": { "type": "object", "properties": { "minute": { "type": "string" }, "markets": { "type": … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "odds": { "minute": "2026-10-10T14:30:00Z", "markets": [ { "id": "5097961", "outcomes": [ { "name": "Yes", "probability": 0.62 } ], "question": "…", "volume_24h_usd": 1751648 } ] }, "as_of": "2026-10-10T14:30:00Z", "perps": { "minute": "2026-10-10T14:30:00Z", "markets": [ { "mid": 83016.5, "coin": "BTC", "mark": 83015, "oracle": 83059.4, "premium": -0.00051, "change_1h_pct": 0.12, "change_24h_pct": 0.53, "funding_hourly": -0.0000059718, "volume_24h_usd": 807655711, "open_interest_usd": 3183000000 } ] }, "provenance": { "daily_root_tx": "https://basescan.org/tx/0x…", "capture_sha256": "…" } } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/manylives-market-data-as-of-snapshot-e79977b7/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from api.manylives.me](https://www.zero.xyz/host/api.manylives.me/llms.txt)
