Solve for
API complexity.
every paid api becomes a callable tool. agents quote, sign, settle in usdc on solana.
RPC
chain rpc, sendTransaction, getAccountInfo. paid per call, settled in usdc.
AI Inference
llm completions, embeddings, vision. claude, gpt, llama. agent picks, 402proto settles.
Oracles
pyth, switchboard, chainlink. per-quote pricing. zero subscription.
Data Feeds
birdeye, defillama, dune. pull data when the agent asks, pay when it gets it.
provider switching on autopilot.
pinning your agent to one provider is brittle. 402proto routes every call through 72+ paid endpoints, picks the cheapest that satisfies the request, retries on failure, settles in usdc on solana.
Multi-Provider Routing
route through 72+ paid apis. cheapest provider that satisfies the call wins.
Smart Retries
failed call lands on a cheaper provider. agent never sees the swap.
Spend-bounded Calls
per-agent usdc cap, enforced on-chain. fleet stays inside budget.
pyth.oracle
price.get SOL/USD
no provider left out.
the router gets a quote in under 100ms, compares it against your spend cap, and signs the cheapest one that fits. failure on one provider routes to the next. agent never sees the swap.
built for every agent use case.
drop 402proto into any api call your agent makes. routing, settle, audit handled.
