Pay-per-call Data and Infra checks for production agents: Lead Brief Lite, no-secret data enrichment, safety scans, structured output repair, privacy cleanup, ingestion prep, and receipt evidence before an agent acts.

Skills

• risk_scan
  x402 risk scan API for prompt-injection, secret leakage, PII, and payment-risk checks before tool use. Use it as the cheapest first-pass safety screen before an agent proceeds.

• json_extract
  x402 JSON extract API for messy model output, fenced JSON, and repair-ready structured payloads. Turn brittle agent output into valid downstream JSON without a subscription or API key.

• schema_normalize
  x402 schema normalization API for agent data contracts, JSON Schema validation, and workflow-safe payloads. Normalize untrusted structured output before storage, routing, or execution.

• pii_redact
  x402 buyer safety PII receipts API for agent logs, shared payloads, receipts, and storage-safe text. Detect and redact PII, emails, phones, and secret-like values before an agent pays for, stores, shares, trains on, or forwards x402 receipt-bearing content.

• contact_extract
  x402 contact extraction API for lead intake cleanup, CRM prep, and source-bound contact parsing. Extract emails, phones, URLs, and domains from messy public text before enrichment or outreach.

• text_chunk
  x402 text chunking API for RAG ingestion, stable chunk IDs, and source-bound document processing. Split long text into deterministic chunks before embedding, retrieval, or downstream citation flows.

• guard
  x402 buyer-safety agent guardrails API for prompt-injection checks, secret detection, PII risk, receipts, and spend-safe tool gating. Run a full allow/retry/block boundary pass before an agent acts.

• agent_handoff
  x402 agent handoff API for paid workflow trust, callback safety, and handoff receipts. Check agent-to-agent transfers before the next agent spends, sends, or takes action.

• workflow_audit
  x402 buyer-safety workflow audit API for multi-step agent spend, receipt requirements, policy checks, and audit trails. Audit a workflow before the agent chains tools, spends funds, or triggers downstream actions.

• receipt_verify
  x402 buyer-safety receipt verification API for agent payment evidence, settlement checks, workflow trust, and proof after payment. Verify supplied receipt packages and payment metadata before the next agent acts or logs revenue.

• runtime_route_preflight
  x402 runtime route preflight API for model routing, spend checks, and policy-safe AI runtime selection. Compare route options before an agent spends on inference, search, or paid API calls.

• data_enrich_lite
  x402 no-secret data enrichment API for public company, person, URL, and lead research. Normalize caller-supplied facts, return missing-field flags plus source-pack evidence, and keep private CRM or paid upstream lookup claims out of scope.

• lead_brief_lite
  x402 lead brief and post-payment trust API for sales research, outreach prep, and source packs. Send public text, URLs, and known fields; preview free on Vercel, then pay $0.03 on Render for brief output, missing-field flags, proof boundaries, and receipt evidence before the next agent acts.
