Crypto market-data lookups (CoinGecko-sourced pricing and market data), paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - search ($0.001): fuzzy-search coins by name/symbol. Requires `q`. Call this first to reso
network.blocknumber ~337 tokens
Read the current chain head — EVM block number or Solana slot — for a supported network. Free, read-only, no wallet needed. Use this to confirm a network is progressing before submitting a transaction, correlate off-chain events with on-chain height, or choose a safe starting point when scanning lo
network.gas_info ~257 tokens

Check the status of a transaction. Supports both EVM (transaction hash) and Solana (signature). Free, read-only. Use this to confirm a transfer landed, debug a failed transaction, or report status to a user. Both `chain` and `transaction_hash` are required. Available chains: solana, solana-devnet,
