Credits & billing

Prepaid credit bundles — a one-time x402 purchase, no subscription. Buy a bundle, then pay every call from your balance by sending x-client-key: <your key> on the request (instead of a per-call payment proof).

Bundle	Price (USD)
`POST /v1/billing/credits/5`	$5.00
`POST /v1/billing/credits/10`	$10.00
`POST /v1/billing/credits/25`	$25.00

Buy: POST /v1/billing/credits/5 (or /10 /25) with the normal x402 payment flow (402 → PAYMENT-SIGNATURE retry). Check balance: GET /v1/billing with header x-client-key: <your key>. MCP: billing_purchase_credits / billing_get_balance.

How payment works

Call a paid endpoint → 402 with a base64 PAYMENT-REQUIRED header describing the exact USDC requirement (scheme exact, EIP-3009 transferWithAuthorization).
Sign the authorization with an x402 client and retry with PAYMENT-SIGNATURE: <payload> (v2; the legacy X-PAYMENT header still works).
The server verifies and settles the payment before serving content; proofs are single-use.
Local dev only (PAYMENTS_MODE=dev): POST /v1/dev-faucet {"endpoint":"<METHOD PATH>"} → { token, expires_at }, then retry with X-PAYMENT (REST) or payment_token (MCP). Not available in production.
