Certified translation, in one API call.

Price a job

curl -X POST https://verdacert.com/api/v1/quotes \
  -H "Authorization: Bearer $VERDACERT_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "source_lang": "ar",
    "target_lang": "en",
    "page_count": 2,
    "doc_type": "birth_certificate",
    "tier": "review_and_certify"
  }'

Returns total price, per-page breakdown, ETA bands, and any surcharges (specialty language, complex doc type, rush). Idempotent.

Submit the order

curl -X POST https://verdacert.com/api/v1/orders \
  -H "Authorization: Bearer $VERDACERT_KEY" \
  -H "Idempotency-Key: $UUID" \
  -F "source_file=@birth_cert.pdf" \
  -F 'metadata={"source_lang":"ar",
                "target_lang":"en",
                "tier":"review_and_certify",
                "draft_translation":"...",
                "callback_url":"https://you.app/wh"}'

Multipart upload of source (+ optional AI draft for the Review & Certify tier). Returns order_id and status. Signed webhook fires when complete.

Signed PDF + a JWS receipt anyone can verify offline against our public JWKS. The verify URL works for end users with no Verdacert account.

Plain HTTP

Bearer-token auth, JSON in / JSON out, multipart for uploads. Feed the OpenAPI 3.1 spec to Stainless, Speakeasy, or Postman for a typed SDK in any language.

Model Context Protocol

Streamable HTTP MCP server at /api/mcp. Seven tools — capabilities, quote, submit, get_status, get_result, refund, verify_certificate — surface natively in Claude Desktop, Cursor, and any MCP client.

Vercel AI SDK tools

Drop-in typed tool exports for generateText, streamText, and the agent-loop primitives. ~150 lines of TypeScript, no extra package to install.

Idempotent submits

Every state-changing endpoint takes an Idempotency-Key. Retry safely after a network blip — duplicates resolve to the original order, no double-charging.

Signed webhooks

Order lifecycle events POSTed to your callback URL with an HMAC-SHA256 signature header and a replay-protection timestamp. TS / Python / Go verification snippets in the docs.

Ed25519 JWS receipts

Every completed order returns a signed JWS receipt the recipient can verify offline against /.well-known/jwks.json. No need to call back to Verdacert.

Sandbox parity

Sandbox keys exercise the full state machine — quote, submit, webhook fires, certificate issues — without billing. Same shape as production, fixture-backed reviewer.

Stable error codes

Documented JSON error envelope with a stable type field, machine-readable error code, and a human message. No surprise 500s; every error category has a documented retry policy.

OpenAPI 3.1 source of truth

The spec at /api/v1/openapi.yaml drives the REST reference, the MCP tool list, the AI SDK exports, and our internal type-checker. One source, three transports.

From scratch

Source in, certified PDF out. Every step done by us — same SKU a law firm orders directly. 14–48h turnaround, rush available.

Your draft, our signature

Send your AI-generated draft alongside the source. A credentialed reviewer compares, edits where needed, and signs the certification. Same legal acceptance, ~50% the price, ~3× faster.

Immigration tech

I-130, I-589, N-400 packet builders. Certified translation is on the critical path of every filing; our API removes the manual reviewer-coordination step from yours.

Legal-tech & court platforms

Foreign-language evidence, contracts, judgments. Higher complexity tier; specialty-language pricing surfaces in the quote API.

Edtech & admissions

Transcript and diploma translation for university-bound applicants. High-volume seasonal demand; rev-share scales with you.

HR & global mobility

Employment letters, residency docs, qualification records as part of cross-border onboarding flows. Bulk volume at predictable margins.

Clinical & medical platforms

Foreign medical records, vaccine certificates, consent forms. Healthcare-aware reviewer pool, same certification standard.

AI agents & vertical copilots

Plug the MCP server into your agent's tool list. Users who occasionally need certified translation now have it — and you earn rev-share without building the back end.
