## Tools
- enrich_tech_risk - Security enrichment: tech-stack fingerprint + CVE mapping + EPSS + CISA KEV + verdict (clear/review/block) for a domain. Cost: $0.05 USDC per call (x402 micropayment). Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- enrich_domain - Firmographic + tech-stack enrichment: RDAP registrant/registrar, DNS records, full subdomain enumeration + certificate-transparency history, tech-stack fingerprint, verdict (clear/review/block, based on domain age) for a domain. Cost: $0.05 USDC per call via the shared MCP payment gate (the direct HTTP endpoint GET /enrich/domain is $0.01 — MCP tools/call is gated at a flat $0.05 per request today). Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- scan_mcp_server - Security-audit a target MCP server for prompt-injection / tool-poisoning. Fetches the server's advertised tools and statically analyzes each for hidden instructions, data-exfiltration hints, dangerous capabilities, cross-tool shadowing, and invisible-unicode payloads (OWASP LLM01/LLM08). Returns findings + a 0-100 risk score + verdict (clear/review/block). Cost: $0.05 USDC per scan via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- scan_mcp_preview - FREE preview scan of a target MCP server for tool-poisoning / prompt-injection. Returns issue count, severity breakdown, risk score, and verdict (clear/review/block) — but NOT which tools or the evidence. Use this to check any MCP server (including your own) at no cost; if issues are found, call the paid scan_mcp_server for the itemized findings + remediation. No payment required. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- crypto_prices - Live spot token prices (price, change_24h, symbol, confidence, timestamp) for CoinGecko ids, sourced from DefiLlama. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- crypto_funding - Live cross-venue perpetual-futures funding rates from Hyperliquid+OKX+dYdX (per-venue rate, arb spread in bps, cheapest-long/richest-short venue, premium/basis, annualized_hl, annualized_okx, LONGS_PAY/SHORTS_PAY/NEUTRAL signal, next_funding_ts, mark/oracle price, open interest, day volume), ranked by volume. Venues that are unreachable or don't list a given coin are omitted per-coin — Hyperliquid is always present. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- defi_yields - Live DeFi lending/LP yield pools (project, chain, symbol, pool id, APY breakdown incl. 1d/7d/30d trend + apyBase7d/apyMean30d, IL risk incl. il7d, exposure, reward/underlying tokens, outlier flag, mu/sigma, DefiLlama stability forecast, TVL, stablecoin flag) from DefiLlama, ranked by TVL (or risk-adjusted APY = apy/sigma). Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- pm_markets - Live Polymarket prediction-market data — question, outcomes, outcome prices, bestBid/bestAsk/spread, volume24hr/volume1wk, oneDayPriceChange, clobTokenIds, conditionId, category tags, liquidity, end date — ranked by volume24hr. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp

- chain_block_number - Current Base mainnet block number via multi-provider JSON-RPC (automatic failover across 4 providers, never fails on one provider's rate limit). Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- chain_gas_price - Current Base mainnet gas price (wei/gwei), EIP-1559 base_fee_gwei/priority_fee_gwei, and gas_price_usd (ETH price cross-call — no price oracle on ETH-only competitors) via multi-provider JSON-RPC. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- chain_balance - Native ETH balance of a Base mainnet address, incl. balance_usd (ETH price cross-call — no price oracle on ETH-only competitors), via multi-provider JSON-RPC. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
- chain_token_balance - ERC-20 token balance of a Base mainnet address via multi-provider JSON-RPC, incl. symbol/decimals/balance_formatted (per-token-contract cached in-isolate). Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp

- chain_token_security - Token security / honeypot detector for a Base mainnet ERC-20: EIP-1967/1822 proxy + upgradeability detection, bytecode dispatcher scan for mint/pause/blacklist/fee-setter/ownership selectors, owner() renouncement check, and a live eth_call state-override simulation testing whether a synthetic wallet can actually transfer() the token. Returns risk_score (0-100) + verdict (clear/review/block) + human-readable flags. Real compute an agent can't trivially self-serve. Cost: $0.005 USDC per call via x402. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp

To analyze an arbitrary token, use the paid chain_token_security tool. No payment required. Endpoint: https://x402-data-api.sigrunner.workers.dev/mcp
