Crypto Dossier

# 🪙 Crypto Dossier **An x402-native market-intelligence endpoint.** One call returns a complete dossier on any crypto token — **by symbol or contract address** — merged from **8 independent sources** into one clean JSON schema, priced at **$0.001 per call**, payable by any agent. Built for autonomous agents, trading bots, and enrichment pipelines that pay-per-call over **x402** — no accounts, no API-key juggling, no rate-limit management. --- ## 💳 Access & payment Speaks **x402-v2 on Base**. Two ways in: **1 · Free trial — Sign In With X (SIWX).** Your first **5 calls are free**. An unsigned request returns `401 siwx_required`; sign the SIWX challenge (EIP-4361 wallet sign-in) to consume one trial. No payment, just a signature. **2 · Pay-per-call — x402.** After the trials, an unsigned request returns the **`402` payment-required** challenge (accepted assets, networks, `payTo` in its header). Sign the x402 headers and the call settles on-chain at **$0.001** — the dossier returns in the same response. `wallet-mcp execute_service` signs both automatically. --- ## 🎯 What you send ```json { "query": "ETH" } { "query": "0x6982508145454ce325ddbe47a25d4ec3d2311933" } ``` A **symbol** (`BTC`, `ETH`, `SOL`) or any **token contract address** (any chain). Also accepts `symbol` / `token` / `address` keys, or a raw-string body. ## 📦 What you get A single, richly-organized dossier (`schema v2.0`): | Section | Contents | |---|---| | **query** | input, resolved type (symbol/contract), symbol, found flag | | **identity** | name, logo, website(s), socials (twitter / telegram / …) | | **price** | consolidated USD price, per-source breakdown, source count, cross-source spread % | | **market** | market cap, FDV, liquidity, 24h volume | | **change** | 1h / 6h / 24h % move | | **cex** | last, bid, ask, 24h high / low, VWAP, volume | | **dex** | top pair (chain, DEX, price, liquidity, volume, link) + pair count | | **ohlc** | 14 daily candles (O/H/L/C/V) | | **fx** | USD → E
