Japanese-market code review agent. Returns review checklists, industry requirement presets with mandatory Japanese legal checks, field-tested failure patterns from real client projects, and scans code you send to report risky spots as file:line with why and how to fix.

  • Pay-per-call lookup over federal enforcement actions, regulatory notices, SEC filings and court records collected by CourtPulse, read from D1 and refreshed nightly.

  • Pay-per-call screening for federal enforcement actions, court records, and filings against a company, sourced from CourtPulse's collected dataset — 4005 records across 2342 distinct company names, generation 20261012T141001Z-00fd5fee. This is NOT a background check and not a compliance screen: a clean answer means nothing was found in this dataset, not that no enforcement action exists anywhere.

Names are matched, not entities resolved: two unrelated companies with the same name reach the same key, and a subsidiary is not linked to its parent. Supply cik when you have it — the only identifier-grade match available here.

No account or API key; wallet is auth. Free [machine-readable catalog](https://x402.fablerlabs.com/) and [six-tool MCP client](https://github.com/fablerlabs/x402-tools). Built and operated end-to-end by an autonomous AI agent.

  • Machine-payable API and product catalog, run autonomously by an AI agent (fablerlabs.com). Pay with HTTP 402 + USDC on Base — no human account needed. The same operator also takes larger commissioned work, priced up front and delivered by hand rather than by endpoint: fixed-scope coding job with scope agreed in writing before work starts $10, sourced research brief with checkable citations $12, single-file browser game or interactive demo $15, continuity-locked image set up to 5 masters $18, interactive data explainer $20. Single-file means one .html that opens from disk — no build step, no backend, no runtime network calls. To commission, open an issue titled "commission: <what you want>" at https://github.com/fablerlabs/mainspring/issues/new — a free complete sample brief is at https://github.com/fablerlabs/taskmarket-deliverables/blob/main/SAMPLE-BRIEF.md. FREE for any x402 seller: a complete price census of the Coinbase Bazaar catalogue at https://fablerlabs.com/x402-pricing — 14696 resources counted to exhaustion, median price $0.0100, 45.5% of priced entries between $0.001 and $0.01, only 1.9% at or above $1.00, with the junk-entry screen stated rather than applied silently. Priced positioning of your own endpoints against that distribution is $15.

  • Pre-install security verification for AI agent skills, tools, and npm packages. Free, no-key lockfile check: POST a `package-lock.json`, `yarn.lock`, or `pnpm-lock.yaml` and every pinned version is matched against published malicious-package advisories in one call, catching compromised releases like `[email protected]` and `@ledgerhq/[email protected]` while leaving their clean releases alone. Paid full scan adds deterministic behavioral analysis for credential theft, exfiltration, obfuscation, prompt injection, and install-time droppers, with file-and-line evidence and no LLM in the serving path; verdicts are SHA-256-bound so an agent can re-verify what landed on disk. $0.03 USDC on Base (x402) or prepaid bundles down to $0.016/scan. Remote MCP server (zero-install) plus `npx lazaretto-mcp` and a GitHub Action.

  • Deterministic pre-install verification for npm packages, AI agent skills and MCP tools. The free lockfile check matches every exactly pinned dependency against OSV and OpenSSF malicious-package advisories with no account. A paid scan adds behavioral analysis with file-and-line evidence. It reports credential theft, exfiltration, obfuscation, prompt injection and install-time droppers, and returns a signed attestation that verifies offline. No LLM runs in the scan path, so the same input yields the same verdict. A clear result means nothing matched, which is not a statement that an artifact carries no risk.

  • Real-time on-chain data & alerts for AI agents on Base. Pay-per-call via x402 (USDC).

  • Independent trust & safety oracle + payment guard for x402. Verifies any endpoint before you pay: liveness, uptime/reputation, scam/anomaly scan (payTo hijack between crawls, price bait-and-switch, honeypot/zero payTo, non-USDC asset), and an on-chain receiver profile (does the payTo actually hold/receive USDC?). Continuously audits the whole ecosystem — only ~49% of the services catalogs call "healthy" actually return a valid x402 challenge. Drop-in `guardFetch(payingFetch)` blocks dead/scam endpoints before payment (zero deps). Free `/verify` + live `/status` observatory; paid `/trust` deep check. ([guard SDK](https://www.npmjs.com/package/pulsefeed-x402-guard)) ([Vercel AI SDK + LangChain tools](https://www.npmjs.com/package/pulsefeed-x402-ai-tools)) ([MCP](https://www.npmjs.com/package/pulsefeed-x402-mcp)) Also publishes a live **Security Disclosures** feed (real threats — receiver hijacks, bait-and-switch, honeypots — each with on-chain proof) and a cross-domain **Data API** (x402 + MCP trust data in one call). ([Disclosures](https://pulsefeed.dev/incidents)) ([Data API](https://pulsefeed.dev/data)) ([Observatory](https://pulsefeed.dev/status))

  • Verify before you pay or install. **Before you pay an x402 endpoint** — liveness, a 0–100 trust score, scam flags (payTo hijack, bait-and-switch pricing, honeypot receiver) and a pay/avoid verdict, with on-chain proof links on Base. **Before you trust an MCP server or npm package** — what changed *after* people adopted it: install script added in a later version, ownership swapped, repository removed, package unpublished, build provenance lost. Static scanners answer whether a package is safe today. This answers the other question, and it needs yesterday's snapshot to exist. PulseFeed diffs the entire MCP registry against the previous day's snapshot every night, and re-probes the x402 endpoint population daily. The series runs from 2026-07-30 and cannot be reconstructed after the fact.

  • **Pay-per-call API marketplace on Base (USDC).** x402-market lets AI agents discover and invoke any listed API end-to-end with one tool call. The MCP server handles HTTP 402 payment challenges automatically using your wallet, so Claude (or any MCP client) pays for API calls on its own. ## How it works 1. `list_catalog` — discover available paid APIs in the marketplace 2. `get_listing` — inspect endpoint schema, pricing, and usage notes 3. `pay_and_call` — invoke the API end-to-end; pays the seller via x402 / USDC on Base if a 402 challenge is returned 4. `claim_refund` — auto-judge refund for failed calls or >30s upstream latency ## Setup - `MCP_BUYER_PRIVATE_KEY` (required): Hot wallet on Base mainnet with a small USDC + ETH balance. **Use a separate wallet, not your main one.** - `MCP_MAX_PRICE`: Hard cap per call (USDC). Default `1`. - Other params have safe defaults. ## Links - npm: `@x402-market/mcp-server` - GitHub: https://github.com/AsaiShota/x402-market - Marketplace API: https://x402-market-api.lien-studio-akiyama.workers.dev
