Pricing

Use a monthly key when request volume is predictable. x402 pay-per-call is not configured on this deployment — GET /v1/pricing reports enabled: false. Detection reduces risk; it does not replace least-privilege tools or output validation.

Instant screening by default · 3,000 deep/mo when you ask for it

Full screening by default — semantic layer on, ~2–4 s. Pass "mode":"pattern-only" per call (or pin it on the org) for ~100–300 ms and no prompt text sent to a model provider. That mode misses paraphrase.
No idle expiry — the plan for an agent nobody is watching
Why was this blocked? One call, one sentence, in English — POST /v1/explain

What it actually returns:

"matched_token":   "paste every temporary password"
"shortest_trigger": "paste every temporary password"
"nearest_clean":    "Removing the extract verb plus the
                     credential object clears
                     intent.sensitive_access_or_exfiltration."
"suggestion":       "This floor does not soften on a
                     declaration, by design."
latency: 21 ms

Server-side bisection: the shortest run of words that still triggers the rule, and the declaration that would clear it — or, honestly, that none would.

Evidence spans: the exact text that tripped each flag
Going over the included volume never stops your screening

DPA, SCCs, vendor questionnaires

Evidence packs, SIEM forwarding, data governance and the framework crosswalk ship with Pro and Team — they are not a fifth plan. A DPA + SCCs or a named contact for a vendor review is a support conversation. We do not sell an uptime SLA until high-availability infrastructure ships. Named contact replies within a business day. That is attention, not an uptime SLA.

Need more than Team’s 500 req/min? Same inbox — named overflow is 1000 instant/min on a granted key, not a public SKU and not an SLA. Checkout for that path is not self-serve.

What an evidence span is

Every plan returns the full flag structure — id, category, severity, confidence and a description of the rule. From Solo up, each flag also carries evidence: the exact text that tripped it. That is the difference between telling someone their message was flagged and showing them the line that flagged it.

  "id": "pattern.override_instructions",
  "label": "Override instructions",
  "severity": 8,

Instant screening is unlimited on every plan, including Free. The deterministic layer costs us milliseconds, so we do not meter it. What the plans include is deep screening — the semantic layer’s model call, which is the only part with a real unit cost. Going over never stops your screening: the request falls back to instant screening and the response says so. “Lowest-cost plan” is the cheapest plan whose rate limit can serve this volume at a 4× peak during 22 × 8-hour business days. Free wins only where 10 req/min is enough for that peak; at fleet volume that is Pro, not a $0 sticker. What the paid plans buy is rate headroom, evidence spans, no idle expiry and support, not permission to keep screening. Going over a plan's included volume is never a cut-off and is not charged as overage today. A dim price means that volume is above the plan’s included deep budget — screening still runs. Above 50,000 deep/mo, Team still screens. Need more than 500 req/min? Talk to us — named overflow is 1000 instant/min on a granted key, not a public price. x402 is pay-per-call with no account, priced alongside so you can compare.

Screen first, pay only for the call.

Prompt screening

$0.005

POST /v1/parse

Output screening

$0.003

POST /v1/screen-output

Quiet on ordinary writing: 0 of 16 harmless newsletter lines refused on this endpoint (prospect run 20, 2026-08-17).

What the call includes. A screening call is priced above the raw classifier endpoints sold by the hyperscalers, and it should be compared for what it carries, not per invocation alone.

Detection does not vary by plan. The same rules, thresholds and verdicts run on every tier including Free — measured, not asserted. A security floor that depends on what you can afford is not a floor. What the paid tiers buy is volume, rate limit, evidence spans on every flag, POST /v1/explain, no idle key expiry, and the forwarding and evidence packs an auditor asks for. On 19 lines of financial-crime investigative prose the deterministic layer refused none; the corpus size and the measured surface are on /docs#precision.

The control plane is not the upsell. Organizations, tool rules, roles, the risk ceiling a member key cannot loosen, and the audit trail are on every plan including Free. A ban you can only afford at $199 is not a security control, it is a paywall. Evidence packs, SIEM forwarding, data governance and the framework crosswalk are included from Pro. What Team buys on top is scale.

Every verdict is recorded against a registered agent, evaluated under your versioned policy, and returned with a receipt — category, score, action and trace_id — that your auditor can read and your SIEM can ingest. That evidence trail, the agent registry, the enforcement dial and the OWASP LLM / NIST AI RMF / EU AI Act / ISO 42001 crosswalk are the product. Screening is the mechanism underneath it. If you need a bare classifier call and nothing around it, a commodity endpoint will be cheaper per request; if you need to show someone what your agents did and under which rule, that is what you are buying here.

Complete x402 endpoint prices

All x402 payments use USDC on Base mainnet. The screening calls most agents need first are $0.005 for /v1/parse and $0.003 for /v1/screen-output.

Endpoint	Price (USDC)	Description
`POST /v1/parse`	$0.005	Screen untrusted input before an agent passes it to an LLM or tool.
`POST /v1/screen-output`	$0.003	Screen LLM output before returning it to users, tools, memory, or other agents.
`POST /v1/analyze`	$0.05	Run standard media credibility analysis.
`POST /v1/evaluate`	$0.01	Evaluate prompt quality, safety, latency, and cost.
`POST /v1/chat`	$0.005	Chat with Parse about analysis results and agent safety.

Should I use x402 or an API key?

Use Case	Recommended	Why
Autonomous first call or marketplace agent	x402	No signup, pay per use
Development/testing	Free API key	No cost, instant setup
Production volume	Pro/Team key	Predictable rate limits and lower operational friction
DPA, named support, or above Team’s rate limit	Talk to us	Support conversation, not a fifth plan. No public Enterprise price until we have one.

Deployment Modes

Choose how deeply each screening call inspects a prompt. Pattern-only mode keeps prompt text away from any third-party model provider — a privacy guarantee you can set as an org-level default so one engineer forgetting a flag can't leak customer text.

Mode	Latency	Prompt text leaves Parse?	Detection coverage	Org-enforceable?
Full (pattern + semantic)	~0.902–3.128s^*	Yes — routed to OpenRouter for semantic analysis	Maximum — catches paraphrased and indirect injection	✅ Set as org default
Pattern-only	~125ms^*	No — text never reaches a third party	High — catches direct injection, boundary manipulation, on-chain planted instructions	✅ Set as org default

^* Latency figures are caller-measured end to end against production, and provisional — a small sample rather than a fitted distribution. Most of that time is not detection: every response carries a latency_ms field with the in-process detection time, which is a small fraction of it. Measure your own path before committing to a budget. See Technology.

How to enforce pattern-only at the org level

PUT /v1/policy
Authorization: Bearer <your-api-key>
Content-Type: application/json

{ "defaultMode": "pattern-only" }

Once set, every screening request for that key is forced into pattern-only mode regardless of the per-request mode field. Individual engineers cannot opt out.

Can we self-host or run this on-premises?

Not the platform, and it is worth saying plainly rather than leaving you to find out. Parse is a hosted control plane — the agent registry, versioned policy and audit receipts exist because verdicts are recorded centrally, and a self-hosted copy would not produce the evidence trail the product is for. There is no on-premises or air-gapped distribution today.

If data movement is the concern: mode: "pattern-only" (per request, or as your org default above) runs the deterministic layer only, so prompt text is never forwarded to the semantic-analysis provider — though it does still reach Parse in the United States. If prompt text must never leave your infrastructure at all, run the open-source prompt-guard library in your own environment: that is a standalone pattern-screening component, not Parse, with no registry, policy engine, receipts or semantic layer. See the FAQ and Trust for the full data-flow picture.
