Why agents pick Vectorway

Built for autonomous callers.

Payment, memory, and identity composed so an agent can finish a job without anyone in the loop.

01

Pay-per-call USDC

Get a 402, sign USDC on Base, get a response. Auth and billing in one round trip.

02

Memory in the gateway

Every call recalls context, generates with LLM, and writes new facts back. No custom vector DB to wire in.

03

Wallet is the account

Your x402 buyer wallet is your account. Memory, credits, and usage are partitioned per wallet.

04

Pre-fund to skip signatures

Sign once for a credit pack. The gateway debits per call from the same wallet, no further signatures.

Pricing

Pay per token, settled in USDC.

The same standard per-token billing. Billed per-request using x402.

Cost calculator

What will my agent actually spend?

Pay only for what your agent actually uses. We authorize a safe ceiling up front, then settle to the exact token count on every call. Pick any model below to estimate costs.

memory_write adds one Flash-Lite summarization call per request, billed by tokens. Pricing subject to change.

Integration

One call. One signature.

Your agent signs USDC on the 402 and gets a chat completion back. No signup. No API key. No human.

  1. 01

    Sign a USDC payment per call

    On the 402 challenge, your x402 client signs an authorization for the per-call cost.

  2. 02

    POST with X-PAYMENT

    Standard chat-completions payload, no API key. The buyer wallet on the signed payment becomes your memory namespace.

  3. 03

    Verify, generate, settle

    We verify the payment, run the call, and settle the exact USDC for the work performed.
