The metered rail has served 100+ calls/minute with no per-call on-chain settlement — only the initial credit top-up settles on-chain.

Do I need an account?

No. You prepay USDC to a session bound to your wallet; the session token is the only credential.

Prepaid high-frequency data for agent loops

Settle once on-chain, then spend credits off-chain — the rail for an agent that polls hundreds of times a minute.

On-chain payment per call is great for occasional requests but the gas cost and block time cap you well below the rate a tight polling loop needs. scrape402's metering rail fixes that: prepay USDC once, then spend credits off-chain per call at whatever rate you like.

Three steps, then loop

# 1. buy credits (on-chain, once)   POST /credits/buy
# 2. open a session (on-chain, once) POST /session/open -> { session_token }
# 3. loop as fast as you want (off-chain, per-call credit debit):
curl "https://x402.shizu.me/m/crypto?pair=BTC-USD" \
  -H "Authorization: Bearer $SESSION_TOKEN"

Each metered call debits credits from the balance you prepaid — no per-call gas, no per-call settlement, no account. Measured at over 100 calls/minute with zero on-chain settlements after the initial top-up. Metered feeds include crypto spot prices, funding rates, randomness, and a token-billed /m/chat LLM endpoint.
