Backed by @faker-js/faker, deterministic via the optional seed parameter.

BitBooth JSON Repair: take any almost-JSON string (LLM tool output, broken API response, etc.), fix the common errors (trailing commas, single quotes, unquoted keys, missing brackets), and optionally validate against a JSON Schema. Built for AI agents that wrap every tool call in defensive parsing. Pay 0.001 USDC per call, no API key, no subscription.

BitBooth JWT Verify: pay 0.001 USDC, verify a JWT signature + canonical claims (iss / aud / exp / nbf) against an inline publicKey (PEM) or sharedSecret. Supports HS256/384/512 and RS256/384/512. Constant-time HMAC compare, configurable clock-skew tolerance, alg=none rejected. Stateless — caller supplies their key in the request body, BitBooth never stores it.

SSRF-blocked, body-capped at 5MB, 10s timeout. Built for crawlers, SEO auditors, and agents that enumerate URLs before paying for the heavier render-pro extraction.

BitBooth Web Diff: pay 0.08 USDC, render any URL with full Playwright JS rendering, and receive both the current markdown snapshot AND a structured diff against the previous markdown you supply. Built for monitoring agents tracking competitor sites, docs pages, pricing changes, or any long-running web change-detection workflow. The first call returns the snapshot; pass it back as previousMarkdown next time to get the diff. No API keys, no subscriptions.

Two-hop resolution via whois.iana.org then the authoritative registry over TCP port 43. 5s per-connection timeout cap. Rejects IPv4/IPv6 inputs and blocks SSRF at the DNS layer.

Bluesky (AT Protocol) public data: an account's profile plus recent posts with engagement counts, or a keyword post search

A live kanban board your agents work on and your human steers, for 30 days. One call returns an MCP endpoint, a key per agent, and a one-click link for your human: no signup, no password. Agents create and move cards; your human watches it happen in real time, drags cards and leaves notes, or connects their own chat to the same MCP endpoint and steers from there. WIP limits and a full audit log live in the database, so no agent can route around them. Free access links, renew for $2.

Board Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

Board/GRC-level portfolio risk aggregator. Pass sector and region. Aggregates the same deterministic capability x opportunity x intent scoring used by /ot/threat-score across the actors relevant to that sector, ranks them, and returns a DeepSeek-written executive summary (BLUF structure, ICD-203 language). Optional compliance_framework noted qualitatively in the narrative. Portfolio-level companion to /ot/threat-score — for vCISO agents and GRC/board-reporting automation.
