POST /v1/cdp/json-repair
utility $0.005 USDC

Take any almost-JSON string (LLM tool output, broken API response, etc.), fix 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.

POST /v1/cdp/render-pro
data $0.05 USDC

Full Playwright JS rendering + Readability extraction. Pay 0.05 USDC, get clean markdown back from any URL including SPAs and JS-heavy sites that naive fetch cannot crawl.

show curl 
curl -s -X POST https://app.heinrichstech.com/v1/cdp/render-pro -H "content-type: application/json" -d '{"url":"https://example.com"}'
POST /v1/cdp/web-watch
data $0.001 USDC

At $0.001 per check, monitor any public URL without carrying page state. BitBooth stores a payer-scoped SHA-256 baseline and reports whether the content, HTTP status, redirect, or content type changed. The first check returns changed:null; page content is never returned or stored. Built for frequent agent heartbeats, release monitors, and pricing alerts.

POST /v1/cdp/xrpl-wallet-watch
data 0.001000 RLUSD

Pay 0.001 RLUSD for an actionable XRPL agent-wallet heartbeat: spendable XRP after reserves, canonical RLUSD trust-line health and call runway, validated activity, balance deltas, failed transactions, and new destinations. The first call establishes a private payer-scoped baseline and skips historical activity.

POST /v1/cdp/web-diff
data $0.08 USDC

Render any URL with full Playwright JS rendering, then return both the current markdown snapshot AND a structured diff against the previous snapshot. BitBooth stores the baseline server-side per payer wallet and URL, so a monitoring agent sends just a URL and learns whether the page changed, what changed, and when it was last checked, while carrying no state of its own. Supply previousMarkdown to diff against your own copy instead.

POST /v1/cdp/webhook-sig-verify
utility $0.005 USDC

Pay 0.005 USDC, verify a webhook signature against the provider canonical HMAC scheme. Supports stripe, github, vercel, cdp, slack, and generic HMAC-SHA256. Constant-time compare, clock-skew tolerance on timestamp-bearing providers. Stateless — caller supplies their secret in the request body, BitBooth never stores it. The boring API plumbing primitive every agent reinvents poorly.

Constant-time HMAC compare, configurable clock-skew tolerance, alg=none rejected. Stateless — caller supplies their key in the request body, BitBooth never stores it. Same plumbing-primitive thesis as webhook-sig-verify, different protocol family.

utility $0.008 USDC

Pay 0.008 USDC, strip emails, phones, SSNs, credit cards, IPv4 addresses, and hex-looking secrets from a text blob before passing it to an LLM, log sink, or third-party API. Pure regex — no LLM inference, deterministic output, sub-cent per call. Compliance primitive for agents in regulated industries (health, finance, legal). Byte counts on the response are auditable evidence of redaction for SOC2 / HIPAA logs.

Pay 0.005 USDC, safely compile + run a regex against a corpus with a hard 50ms CPU deadline. Returns structured matches (index, length, full match, capture groups). Supports JS engine flags g/i/m/s/u/y/d. Catastrophic backtracking surfaces as a regex_timeout instead of stalling the caller. The plumbing primitive every agent that consumes user-supplied regex reinvents poorly.

Returns og:title, og:description, og:image, og:type, og:site_name, og:url, the full twitter:* card block, plus standard HTML head fields (title, description, canonical, favicon, lang). Pure JS regex extraction, no LLM, no headless browser. 8s timeout, 512 KB body cap, non-HTML rejected. The lightweight pre-flight before paying for the heavier render-pro extraction.

Errors surface as 502 with reason (captions_disabled, no_captions, language_not_available, video_unavailable, rate_limited). Built for agents that summarise, classify, or search video content before paying for the heavier LLM token cost.
