What's new

• Buy Custom access with a stablecoin wallet. A single purchase can now be up to $100, enough for up to 30 days of Custom access at $1.30 a day, with no subscription or signup. An agent can put your own providers behind Lasso and pay for the trial itself. Trial your own providers

​

Accounts for people and agents

• One account holds your keys, profiles and balance. People and agents work on it as members, each with their own credential and permissions, and the dashboard shows its balance, subscriptions and usage per key. Accounts, people and agents
• An agent can set up Lasso without a signup. One unauthenticated POST /api/v1/keys creates an account with its agent, a first key and a $0.025 starting balance, and returns its RPC URL. Quickstart
• Hand an agent’s setup to a person. The agent requests a single-use claim link. Claiming keeps it as a new account or merges it into one you already have, with a preview of the combined balance, keys, rate limits and agents before you confirm. Every key and URL keeps working. Accounts, people and agents
• Bring an agent into an existing account. The agent asks to connect and gets an approval link; once an admin approves, it works on that account. Accounts, people and agents
• Rotate a key with no downtime. The old secret keeps serving for the grace period you choose, so each deploy switches over in its own time. Rotate a key

​

One balance, priced per method

• One USD balance per account. Every request is priced by method and strategy, and each response tells you what it cost in x-lasso-cu and x-lasso-usd. Chains and prices
• Top up with a stablecoin wallet, no Lasso credential needed. Credit requests answer with a standard 402 challenge for x402 (USDC on Base) or MPP (USDC.e on Tempo); any stock client can pay it. Balance and payment fallback
• Your app keeps serving when the money runs out. An account that has paid before falls back to public providers for 30 days while you top up, marked with x-lasso-fallback: payment. Balance and payment fallback
• Free access, Pro and Custom are account subscriptions. Included usage is counted in CU per month, and usage beyond it draws on the balance. Serving access and pricing

​

API and signals

• The account API lives at /api/v1, described in full by openapi.json. Agent API v2 RPC URLs keep working. Upgrading from Agent API v2
• WebSocket RPC on every key, including keys an agent creates. Keys and profiles
• Every response explains itself. x-lasso-request-id, x-lasso-access, x-lasso-balance-usd and the RateLimit headers show who served the request, what it cost and how much room is left. Errors that Lasso originates carry a code and a next_action, listed in one reference. Signals and errors

​

Changes to note

• An RPC key can no longer request a claim link for an account an agent created; the agent requests it. Accounts migrated from keys that predate agents still claim with their key. Accounts, people and agents
• Keys an agent creates share their account’s rate limit instead of each getting 50 RPS. Serving access and pricing
• Free access is counted in per-method CU instead of bytes. Serving access and pricing
