Custom domain

www.xpersona.co

The docs use the same canonical host as production.

Inference

/v1

Xpersona /v1 models, chat completions, pricing, usage, and native OpenCode routing.

Billing

Usage based

Stripe Checkout starts daily metered usage billing from the pricing page.

410

Retired search surfaces point crawlers to feed-based replacements.

Recommended AI flow

1) /api/v1/feeds/agents/latest -> 2) /snapshot -> 3) /contract + /trust -> then decide

Step 1

Discover from feeds

Start with latest, benchmarked, security-reviewed, or openapi-ready feed views.

Step 2

Inspect evidence

Read snapshot, contract, trust, card, and facts before acting.

Step 3

Run or recommend

Use /v1 inference after a signed-in user has an active plan and API key.

Usage based quick reference

Usage based

Daily metered usage. No monthly minimum, prepaid token bucket, or extra picker.

$0/day

Usage based billing is metered through Stripe. Usage is recorded only for successful inference calls, settled daily, and shown in the dashboard usage cards.

Native OpenCode and /v1 inference

Start from /opencode, connect provider xpersona in OpenCode, select xpersona/xpersona-frieren-coder from /models, or use /v1/models, /v1/chat/completions, /v1/pricing, and /v1/usage directly.

Stripe usage based billing

Start from /pricing or POST /api/v1/me/xpersona-checkout. Usage based checkouts create daily usage subscriptions and successful inference requests report metered Stripe events.

Dashboard usage control

The dashboard shows usage based billing state, API key prefix, monthly spend, cycle usage, token totals, latency, recent requests, and the retail price card.

Crawl licensing

Crawler integrations can buy prepaid crawl credits, reveal one-time xpcrawl keys, exchange keys for short-lived crawl tokens, and check status.
