Authentication

Every call needs a key. Send it in a header called Authorization, like this: Authorization: Bearer YOUR_KEY. If you prefer, X-API-Key: YOUR_KEY works too.

A key is just a long password that starts with lf_. Treat it like a bank card: anyone who has it can use up your quota. Do not put it in a public web page or a shared git repo.

Pay per call, no account needed

You do not have to sign up. If you call an endpoint with no key, we answer with 402 Payment Required instead of an error. The reply is a small block of JSON that tells you three things: how much the call costs, which wallet address to pay, and which coin network to use.

Pay that amount in USDC on Base, then send the exact same request again with an X-PAYMENT header. We check the payment and return the answer. No signup, no email, no card.

Most endpoints cost $0.002 per call. Heavy ones cost $0.01 - those are the ones that do real work, like building a PDF or taking a screenshot. Every price is listed at GET /v1/prices on any worker, so a program can read the list instead of guessing.

If you would rather pay nothing, get a free key below. Both routes reach the same endpoints.

Rate Limiting

Limits are counted separately for every endpoint, and they reset each day. So the free tier gives you 100 calls a day to each endpoint, not 100 calls in total.

The last column is a speed limit: how many calls per minute we accept from one key before asking you to slow down.
