List and search scored x402/MCP tools

Paid webhook/API execution for autonomous agents. Executes one public HTTPS action after x402 payment, applies retries and idempotency, then returns a signed receipt with request hash, response hash, target, status, and attempt count.

Freshness Decay pack: Compare cache age, Fresh/Stale/Unknown, decay pressure + machine brief. Freemium card is free. Not a trade clock or APY. Gap ≠ Activity ≠ Variance ≠ Green ≠ Freshness. Task: Call when an agent must check whether a Compare row is stale before citing APY or allocating on a cached quote. Why pay: $0.12 ≪ pricing or citing an APY from a Stale/Unknown cache pull. Pay for the decay

Research an ecommerce store, online business, or ecommerce market using current public sources. Returns store analysis, categories, positioning, pricing patterns, offers, policies, competitors, market research, and citations.

Validate a number by the Luhn (mod-10) algorithm — the scheme behind credit/debit card numbers and many IDs. Spaces and hyphens are ignored. A mismatched check digit is a successful { valid: false }.

Calculate kg/l unit prices for up to 50 rows of price_eur plus quantity text or EAN. Example: items [{price_eur:1.29,quantity:"500 g"}]. Errors are reported per row; kg and litre groups are not comparable. Empty batches with no usable line are not charged. No observed store offer.

Monthly German-origin quotation shares across all available BLE years for every product group or a list. Example: products ["Tomaten","Gurken"]. Counts and years per month; mass and piece units stay separate. Quotation share is neither market share nor harvest availability.

The complete daily observation history of third-party x402 endpoints since first observation, with the Merkle root of each day.

Split an amount into parts using integer minor-unit math so the shares always sum back to the exact original — no rounding drift. Pass parts for an even split, or ratios for a weighted one (e.g. [1,1,1] splits $100 into 33.34/33.33/33.33). The leftover minor units go to the largest fractional remainders.

Scan source code or configuration text for hardcoded secrets: AWS access keys, GitHub/Slack/Google tokens, Stripe and OpenAI keys, PEM private-key blocks, JWTs and high-entropy secret assignments. Placeholder values are filtered out. Each finding gives the rule, a severity (critical/high/medium/low), line and column, entropy and a masked excerpt. Offline and deterministic.

Email intelligence for a company domain: mail provider (Google Workspace, Microsoft 365, Proofpoint...), catch-all status, SaaS tools revealed by SPF (HubSpot, Salesforce, Zendesk, SendGrid...), DMARC policy, public email addresses found on the company's own website with source URLs, and the likely address pattern. Useful before cold outreach or for tech-stack prospecting.

Simulation, not investment advice.

One combined go/no-go before an agent spends: PROCEED / CAUTION / ABORT from the token's market verdict, the counterparty wallet's sanctions, age and poisoning check, and — with a spender — its ERC-20 approvals. A leg that cannot be evaluated returns unknown and caps the verdict at CAUTION. Mode 'compact' returns the decision, the worst leg, and one summary per leg. Use this when an agent is about

Public, account-free preflight for an autonomous x402 payment. Validates the merchant's exact PAYMENT-REQUIRED challenge against the intended request, checks Base USDC payment integrity and public merchant/payTo risk evidence, and returns APPROVED, REVIEW or DENIED with signed proof. It does not grant spending authority: an APPROVED result means the transaction evidence is clear enough to proceed
