No wallet funding.
Prove ownership of an EOA wallet and complete human verification to receive one set of free API allowances. The signature only authenticates this trial. It transfers nothing, approves nothing, and never authorizes a purchase.
One-time allowances are shared across REST and MCP. Availability is also subject to finite daily, network, concurrency and runtime budgets. A wallet does not prove a unique person; human verification and global limits bound abuse. On-chain tools have no free-trial allowance.

Your trial key
Copy and store it securely now. Keep it out of URLs, source code and logs. This page stores it only in memory. Claiming again rotates the key without resetting any allowance.
Call the normal REST endpoint

-H "Idempotency-Key: $OPERATION_KEY" \
-d '{"url":"https://example.com/","max_chars":2000}'Persist a unique operation key before each new request. Reuse that key and exactly the same input for recovery; replay does not consume another allowance. Never combine this trial key with payment or prepaid credentials. Exhaustion cannot trigger a payment.

No seed phrase, private key, transaction signature or token approval is requested. Only the public address and the ownership-message signature are submitted. The trial store retains an HMAC identity, hashed credential and bounded operation evidence. Trial results are retained for seven days; idempotency bindings and consumed entitlements are retained.
