01What Scribe does
Scribe is a counter for the lookups and conversions AI agents do in loops, operated by Vima Brosta LLC. Every product is synchronous and stateless: send the request, pay once (x402 / USDC), receive the answer in the same response. There is no id to poll, no secret to keep, and nothing stored. A request that cannot run (malformed, a private address, an unreachable target, an upstream that is down) is refused before payment and costs nothing.
No accounts, no API keys, and no Idempotency-Key: a retry is a new purchase, the
same as any synchronous counter, so retry only when you did not receive an answer.
domain $0.005 · translate $0.01 · convert $0.01 · render $0.02. Per request. No subscriptions, no hidden fees.
02Payment (x402)
- Send the request with no payment. You receive HTTP 402. The
PAYMENT-REQUIREDheader (base64 JSON, mirrored in the body underrequirements) carries every enabled payment option. If the request would be refused, the body says so underpreflightbefore you sign anything. - Pay and retry the identical request with the
X-PAYMENTheader (@x402/fetchwraps this in one call). - The answer is in that response. A refusal after payment was presented (an unreachable target, an upstream outage) is a 4xx or 5xx, which never settles.
03Paid endpoints
Everything public about a domain, in one JSON. name is a hostname, or a URL
whose host is used. POST /v1/domain {"name": "..."} is the same product. A bare
paid GET with no name runs against example.com and says so.
{ "registration": {"registrar", "created", "updated", "expires", "status", "nameservers", "source"} | null, "dns": {"a", "aaaa", "mx", "ns", "txt", "cname"}, "tls": {"subject", "issuer", "valid_from", "valid_to", "days_left", "alt_names", "fingerprint_sha256", "protocol"} | null, "http": {"url", "status", "server", "content_type", "location"} | null, "errors": {only the parts that failed}, "resume_hint", "receipt" }
Registration comes from RDAP through the IANA bootstrap; a subdomain is looked up at its
registrable name. DNS is a live resolution. The certificate is whatever port 443 serves, read
without verifying the chain: the answer is what is there. The HTTP front door is one GET at
https://name/ with redirects reported, not followed. Each part is best effort and
reports its own error, so a name with no web server still gets DNS and RDAP.
{"text": "…", "target": "es", "source": "en"} # 2,000 chars; target is an ISO 639-1 code or a name; source optional
Returns translation, source_language (detected), target_language,
characters, model, and usage. Formatting, line breaks,
names, numbers, URLs, and code are preserved. The text is treated as material to translate,
never as instructions. Runs on claude-haiku-4-5.
422 translation_refused (the model declined), 502 or 503
provider_unavailable (retry shortly).
{"from": "url", "to": "markdown", "input": "https://example.com/"}
Pairs: html>markdown, html>text, markdown>html,
markdown>text, url>markdown, url>text,
url>html, pdf>text. input is the source (512KB), a
public URL (fetched under the URL policy, 2MB, truncated set past that), or a PDF
as base64 or a public URL (5MB, 200 pages). A URL that serves a PDF converts to text.
Returns output, title, pages, source_url,
source_bytes, truncated, characters. Conversions from
HTML or a URL drop scripts, styles, navigation, headers, footers, asides, and forms, and keep
the main or article element when the page has one.
{"from": "url", "to": "pdf", "input": "https://example.com/", "full_page": true, "viewport_width": 1280, "viewport_height": 800, "format": "binary"}
input is a public URL or your own HTML (256KB). With format
binary (the default) the response is the file itself: application/pdf
or image/png, Content-Disposition: inline, and
X-Scribe-Product and X-Scribe-Price headers. With
base64, or an Accept: application/json header, the response is
{"content_type", "bytes", "base64", "receipt"}. Output is capped at 15MB.
422 render_failed or output_too_large, 502 or 503
provider_unavailable.
04URL policy
- Schemes: http and https only. Embedded credentials are refused.
- Ports: 80, 443, 8080, 8443 only (
blocked_port). - Hosts: public only. Private, loopback, link-local, carrier-NAT, and cloud metadata addresses
are refused, as are
*.local,*.internal, and*.localhostnames and hosts that resolve to private addresses (blocked_host). Resolution is re-checked at connection time. - Redirects: followed up to 4 hops on a conversion, every hop re-entering this policy; reported and not followed on the domain front door.
- The fetcher identifies as
ScribeFetch/1.0 (+https://scribe.vimabrosta.com/bot). Site owners: /bot.
