$0.01 per 1M input tokens. Output is free. How tokens are counted, with a worked bill.

The price #

The Preview plan is free, with no card. Access is by invitation during the preview: request access. Your Usage page and GET /v1/usage show what your usage would cost at list price, so you can plan ahead. During the preview you are not charged.

The pricing page always shows the current price, read live from the API.

How tokens are counted #

• Input tokens = tokens of the document + tokens of the question, for every question read.
• Output tokens = tokens of the answer text. They are free.
• /v1/extract reads the document once per field, so a call with 6 fields is billed like 6 questions.

A token is a piece of a word. For English text, a token is about 4 characters, so 1,000 characters are about 250 tokens. The exact counts are in every response:

"usage": {"input_tokens": 230, "output_tokens": 3, "total_tokens": 233}

An example bill #

A team reads contracts. Each month it has:

• 1,000 contracts;
• 10 pages each, at 3,000 characters per page: 30,000 characters, about 7,500 tokens;
• 5 questions per contract: the parties, the start date, the notice period, the renewal terms and the liability cap.

The bill:

one question:  7,500 document tokens + 15 question tokens = 7,515 input tokens
one contract:  5 questions × 7,515 = 37,575 input tokens
one month:     1,000 contracts × 37,575 = 37,575,000 input tokens
cost:          37,575,000 ÷ 1,000,000 × $0.01 = $0.38
output:        free

That is $0.00038 per contract. It averages about 1,252,500 input tokens a day, within the preview limit of 2,000,000 per UTC day.

Spend less #

• Send the part that matters. Every question reads the whole document. A two-page section costs a fifth of a ten-page contract.
• Ask only what you need. Five questions are five reads.
• Convert once. Keep the text from /v1/convert and reuse it.

Limits #

The Preview plan allows 60 requests per minute, 2,000,000 input tokens per UTC day and 5 active keys per account. See rate limits.

Compared with other APIs #

At $0.01 per 1M input tokens, XERJ Reader is about 4x below Jev's $0.042 and 10x below Cloudflare Clairic's $0.10 preview price, as of November 2026. Both of those also bill input only. Sources and details are on the compare page.
