Base → Solana USDC microbridge discovery. Default example uses 1.00 USDC deposited to the Base bridge wallet. Provide a Solana receiver address and an amount (min 0.01 USDC, max 50.00 USDC, steps of 0.01) to create a concrete bridge quote. The bridge charges a 2.5% commission; the remainder is delivered as USDC on Solana.

Storage & Infrastructure

Create a Solana associated token account (ATA) for a given Solana wallet and SPL mint, paid via Base USDC. Typical use: prepare a Solana wallet to receive USDC or other SPL tokens before sending funds or using bridge flows. Cost: 0.4 USDC per call, paid on Base. The endpoint checks via Solana RPC whether the ATA already exists; if it already exists at execution time or creation fails, the server attempts to refund the 0.4 USDC payment on Base.

Base GPT wrapper API using x402 payments. Default direct call: model gpt-5-mini, max_output_tokens=2000, fixed price 0.01 USDC for up to 1000 input tokens. For all other settings the price is computed per model as (input_tokens * input_price_per_million + max_output_tokens * output_price_per_million) / 1,000,000, with a minimum of 0.001 USDC and always rounded up to 6 decimals. Optional max_input_tokens lets you cap the input tokens used for pricing; if the message is longer than this cap the server returns an error instead of under-pricing. Optional action=message (or omitting action) performs a direct GPT call with the given message. Optional action=create creates a custom agent with the given message as preprompt for 0.001 USDC (no OpenAI call), stores a base_price_usdc using (max_input_tokens_for_agent or 1000) + preprompt + max_output_tokens, and returns a custom_id. Optional action=list lists up to 100 recent custom agents for the paying wallet for 0.001 USDC without calling OpenAI. Custom agents can be called via POST /base/llm/gpt with custom_id, or POST /base/llm/gpt/{custom_id}. Each custom agent has a fixed price per call based on its stored preprompt, model, max_output_tokens and max_input_tokens; if the runtime message is longer than max_input_tokens the server returns an error. This specific request uses model gpt-5-mini with max_output_tokens=2000. Pricing mode: default. Prepaid price (x402) for this request: 0.010000 USDC.

Base text-to-speech API paid via x402. Converts text input into a hosted audio URL. Dynamic pricing for TTS: the prepaid price is computed per request based on the input and charged upfront via x402. Prepaid price for pure discovery requests without text is an upper bound; clients should re-run discovery with their concrete input if they need an exact quote.

Solana → Base USDC microbridge. This request will accept a payment of 12.350000 USDC on Solana to the bridge wallet and, after a 2.5% commission of approximately 0.308750 USDC, will attempt to deliver around 12.041250 USDC on Base to the specified receiver. If the Base transfer cannot be completed after 2 attempts, the bridge refunds the full original amount on Solana; if the refund also fails after 3 attempts, the bridge is marked as failed and manual support is required.
