Lodestar Stamp

For agents and platforms

Metered reads. The record stays free.

Every receipt is free to read on this site and by single lookup, with or without a key. If your agent or platform reads receipts at volume, order a key: thirty free days from your first keyed read, then a per-read price or a monthly tier. The key never gates or changes an answer.

Charter: Payment never touches the record. Receipts are free and public. Nothing on the record is for sale: no placement, no leads, no field on any receipt.

Terms, effective 2026-09-04

Always

Free

The site, every receipt page, every single lookup, the change feed and the MCP server, key or no key.

$0 always

  • No key, no account
  • Optional X-Lodestar-Consumer so we can count you

Keyed reads

Per read

Thirty free days from your first keyed read, then five cents a receipt read, invoiced monthly.

$0.05 / read

  • Single, batch, change feed and MCP
  • Reads tagged trial or paid on our counter, never on the receipt

Volume

Monthly tier

$50 per thousand reads with a $500 monthly minimum (10,000 reads in the minimum), invoiced through Stripe. Platform tiers from $2,000 a month add batch at scale, the change feed, a service level and a named contact.

$500 / month minimum

  • Same receipts, same bytes
  • Platform tier quoted on this form

The per-read price is a placeholder until one consumer has paid it for thirty days. The first order is the price test, and the terms you sign are the terms you keep. Machine-readable: https://api.lodestarindex.com/v1/pricing.

Order a key

We email a key within one business day. Send it as X-Lodestar-Key on every read. Nothing else changes.

How a keyed read works

  1. GET the same endpoints as before and add X-Lodestar-Key: <key>.
  2. The answer is byte for byte the answer an unkeyed read gets. The response carries X-Lodestar-Tier (trial or paid) so you can see what the read cost.
  3. Our counter records the read's tier. The receipt records nothing about you, ever.
