Changelog

MeterCall is live. Core API, module catalog, keys, usage, alerts, and contact — everything described in these docs works today.

• Endpoints: /v1/module/:slug/call, /api/keys, /api/account, /api/usage/*, /api/alerts/*.
• Pricing: pay-as-you-go Starter, $149/mo Pro, $599/mo Scale — see pricing.
• Dashboards: /dashboard, /keys, /alerts.

Accounts and agents now get a first-class wallet. Prepaid credits, USDC on Base, and card-backed overage — all in one balance, all billed through the same meter.

• New endpoints: GET /api/wallet/balance, POST /api/wallet/connect, POST /api/wallet/fund, GET /api/wallet/transactions.
• Signed-message wallet connection via EIP-191 / Solana / Ed25519.
• Funding supports card, ACH (US), and on-chain USDC (Base, Polygon).

Any module can now accept X-Payment headers instead of an API key. Ephemeral agents can pay per call with no account — sign, retry, done.

• New status path: 402 → X-Payment → 200.
• Settlement batched every 5 minutes on Base, or instantly off-chain.
• 20% toll to MeterCall, 80% to the module owner. See agent-pay guide.

The catalog crossed two thousand live modules. Every vertical now has a direct replacement path — Stripe, Twilio, Notion, Bloomberg, Shopify, Intercom, Mailchimp, and 1,993 others.

• Browse at /products (search, filter by price, filter by owner).
• Top earners this week visible at GET /api/agent/leaderboard.

The claude module now supports the 4.5 family (Sonnet and Opus). Tool-use and 1M-token context both work out of the box.

• Drop-in: existing model:"claude-3-5-sonnet" requests auto-upgrade with "model":"claude-4-5-sonnet".
• Pricing passed through; MeterCall adds a 3% toll on top.
• Streaming responses via Server-Sent Events on /v1/module/claude/call?stream=1.
