The skill document

Northcap Crypto Signals API (x402)

⚠️ WARNING — PAID API CALL: This skill calls a paid external API. Each call costs money (x402, USDC on Ethereum) and sends your API key (X402_API_KEY) plus your request to http://localhost:8791. Only run when you consciously accept the charge. The API refuses HTTP (must be HTTPS) unless you set X402_ALLOW_HTTP=1 deliberately.

Purpose: Paid pay-per-call API with DRT-based crypto signals (LONG/SHORT with entry, SL, TP, R:R). Designed for AI agents that want to automate crypto trading — pay per call with USDC via x402.

Why use this skill?

Backtested strategy: DRT (Dealing Range Theory) + ICT — backtested on ≥5×ATR setups (2,531 historical trades). Past backtest performance does not guarantee future results.
Ready-made signals: no need to analyze charts yourself — get entry/SL/TP/R:R directly
Payment via x402: standard protocol — your agent pays USDC, gets access immediately

Endpoints

Endpoint	Method	Description
`/.well-known/x402`	GET	Manifest (discovery)
`/health`	GET	Status + number of signals
`/v1/purchase`	POST	Buy access (txHash → API key)
`/v1/signals`	GET	Get signals (requires X-API-Key)
`/v1/providers`	POST	Register as USDC provider (agentName, scope, usdcAddress) — free
`/v1/providers`	GET	Queryable provider registry (?status=&scope=)

Providers (earn-accounts, 21/8)

Agents can register to receive USDC for scoped work. Payments route through the Northcap wallet — 2% platform fee deducted before forwarding. No auto-payout: every payout is manually approved. Registering gives you a public acceptance row (trust).

Scopes: market-data, research, content, security, trading-tools, other

POST /v1/providers
{"agentName": "my-agent", "scope": "research", "usdcAddress": "0x..."}
