# Pricing

> Spark trial, Sprint / Mission / Deploy credit packs, per-call rates, auto top-up — capabilities 4.2.0.

Lithtrix pricing is **credit-pack based**: **Spark** trial on register, then **Sprint**, **Mission**, and **Deploy** one-off packs via the API. **Metered debits:** **Search $0.005** and **Browse $0.005** per successful call. Pack grants **expire in 180 days** after purchase (UTC). See **`GET /v1/capabilities`** for **`tier_descriptions`** and the numeric **`pricing`** block.

## Headline framing

**Spark to start. Sprint, Mission, or Deploy when your agent has work to do.**

Paid packs are a **private workspace** for your agent to **search**, **browse**, and **remember**.

## Spark (trial)

* **\$5 in credits** on signup — **no card**
* **Browse is not included** — **buy Sprint (or Mission / Deploy) to unlock Browse**
* Rough coverage: on the order of **\~1,000 searches** at **\$0.005**/search (usage varies with other operations)

## Sprint — \$25

* One-off credit pack · **180-day expiry** on granted credits
* Order-of-magnitude **\~5,000 searches** or browse calls at **\$0.005**/call
* **Browse** included once purchased

## Mission — \$50

* One-off pack · **180-day expiry**
* Order-of-magnitude **\~10,000** metered calls at **\$0.005**/call

## Deploy — \$100

* One-off pack · **180-day expiry**
* Order-of-magnitude **\~20,000** metered calls at **\$0.005**/call

## Per-call rates

* **Search:** **\$0.005** per successful call (trial and packs)
* **Browse:** **\$0.005** per successful call (requires paid pack)

## Auto top-up

**Set a threshold. We refill automatically. Your agent never stops mid-task.**\
Configure via the billing API with a saved payment method (see **`GET /v1/capabilities`** and agent guide).

## Checkout

Use **`POST /v1/billing/packs/checkout`** with your Bearer token (pack: `sprint` | `mission` | `deploy`). Spark is the trial pool and is **not** sold as a pack.

## Legacy subscriptions

Some older accounts may still show **Starter / Pro** monthly billing in **`GET /v1/billing`** — contact support if you need to migrate.

## Referrals

Optional **`referral_agent`** on **`POST /v1/register`**: when set to another agent’s UUID (their **`referral_code`** from **`GET /v1/me`**), that referrer receives **+\$0.50** in credits per validated signup (no cap; self-referral excluded).
