Quickstart

Three verification engines behind one simple API: document forensics, AI-text detection, and citation fact-checking. No API key, no signup — your first call works from a terminal in under a minute.

Fact-check a report by URL

Point POST /v1/verify-references at any public report or article. Stipple fetches it, resolves every citation, recomputes the document's own arithmetic, and returns a structured verdict with a shareable permalink.

bash

curl -X POST https://www.stipple.sh/v1/verify-references \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com/report.pdf"}'

The response is a trust summary plus per-item tables:

json

{
  "summary": {
    "references_total": 63,
    "references_live": 57,
    "references_archived": 3,
    "references_dead": 3,
    "papers_mismatched": 1,
    "internal_issues": 0,
    "headline": "60/63 citations resolve; 1 mis-attributed paper; 3 dead links"
  },
  "references": [ ... ],
  "claims": [ ... ],
  "internal_consistency": [ ... ],
  "limitations": "Reports verification coverage, not truth. ...",
  "check_id": "fc_6d22fb4033cbac40",
  "permalink": "https://www.stipple.sh/fc/targeted-compliance-framework-review-6d22fb4033cbac40"
}

Results report verification coverage, not truth: "supported" means evidence-backed, "unsupported" means no evidence found. The tool shows a reviewer where to look — it never certifies a document.

Verify a document for tampering

Upload a PDF or image to POST /v1/warrants for forensic inspection — tampering signals, structure and metadata analysis, arithmetic reconciliation. You get back a warrant: a risk band, findings, and a shareable record.

bash

curl -X POST https://www.stipple.sh/v1/warrants \
  -F "file=@payslip.pdf"

Detect AI-written text

Send prose (or a URL or file) to POST /v1/detect-ai-text. It returns a probability with the specific tells, and abstains on non-prose documents where style detection is unreliable.

bash

curl -X POST https://www.stipple.sh/v1/detect-ai-text \
  -H "Content-Type: application/json" \
  -d '{"text": "Paste the prose you want to check here..."}'

Limits while free

Anonymous use is rate-limited per IP: 20 documents/day, short bursts up to 10 requests, 25 MB max upload. A free API key (instant, no account) bumps you to 50/day on your own quota with usage metering. Details in Errors & limits.
