NameVerdict API

Programmatic six-lane preliminary name-risk screening for AI agents and developer tools. Use a prepaid bearer key or let a compatible agent pay for one request through Stripe Machine Payments Protocol.

Live pay-per-request API

Let an agent purchase a screening when it needs one

Send one to five candidate names to POST /api/mpp/clearance. The endpoint returns an HTTP 402 payment challenge; a compatible MPP wallet authorizes and retries the request, then receives a private one-job token for polling the result.

One candidate
$39 USD per request
Two through five candidates
$99 USD per request

Prepaid API keys

Prefer to buy first and integrate later? These bundles require no NameVerdict account and never expire.

1 Use

$39

One preliminary screening call, any single candidate name.

5 Uses

$99

Five preliminary screening calls. Spend them across names or batch them.

How prepaid access works

  1. Buy a bundle. We email you a key (nv_live_…).
  2. Hand the key to your agent. Each call burns one credit per name.
  3. Lost the key? Reply to the receipt email — we'll reissue.

Machine-payment flow

  1. POST one to five names, the product brief, optional Nice class, and a globally unique Idempotency-Key.
  2. Handle the returned MPP HTTP 402 challenge with a compatible wallet and retry using its one-time payment credential.
  3. On HTTP 202 (or HTTP 200 for an exact paid retry), retain the returned statusUrl and private statusToken. An exact retry returns the original job without another charge.
  4. Poll about every five seconds until the job is done, failed, or refunded.
# Initial request: a compatible MPP client handles the 402 and paid retry.
curl -X POST https://nameverdict.com/api/mpp/clearance \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: 7c0e6674-7425-40de-944b-e07fc1f90ae7" \
  -d '{"names":["orielpath"],"niceClass":9,"productDescription":"Supply-chain forecasting software"}'

Quick start

# Submit one or more names (max 5 per request, ≤ uses_remaining)
# Optional Idempotency-Key (8-128 chars A-Za-z0-9_-): retrying with the
# same key returns the original job instead of spending credits again.
curl -X POST https://nameverdict.com/api/clearance \
  -H "Authorization: Bearer nv_live_..." \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: my-run-2026-08-20-a" \
  -d '{"names":["acme","rocket"],"niceClass":9,"productDescription":"open-source CLI tool"}'

# Response
# { "ok": true, "jobId": "abc123", "statusUrl": "https://nameverdict.com/api/clearance/abc123",
#   "creditsRemaining": 3, "namesQueued": 2 }

# Poll until done
curl https://nameverdict.com/api/clearance/abc123 \
  -H "Authorization: Bearer nv_live_..."

# {"status":"running", ...}  → poll again in ~5s
# {"status":"done", "report": {...}, "reportUrl": "...", "creditsRemaining": 3}
# {"status":"failed", "error":"internal_error", "creditsRefunded": 2}

Limits & policies

What the API returns—and what it does not

Both purchase routes return the same automated six-signal preliminary NameVerdict report: domains, common-law usage, selected social handles, structured USPTO evidence, web-search landscape, and category collisions. This is not a comprehensive trademark search, trademark clearance, legal advice, attorney review, or a guarantee of availability, registrability, or non-infringement. GREEN means the completed preliminary checks found no material concern; it is a useful filter for deciding which candidates deserve professional and legal review, not a recommendation to adopt or file.

Machine-payment questions

Can an AI agent purchase a NameVerdict screening without a prepaid API key?

Yes. The live Stripe Machine Payments Protocol endpoint accepts a compatible one-time payment credential, charges $39 for one candidate or $99 for two through five candidates, and returns a private token for polling that screening job.

Does the NameVerdict API provide trademark clearance?

No. Both API purchase routes return the same automated six-lane preliminary name-risk screening as the browser product. They do not provide a comprehensive trademark search, legal advice, attorney review, or any guarantee that a name is available or legally safe.
