afta_federation_membersList confirmed AFTA federation membersread-only
Returns the canonical list of confirmed Agent Fair-Trade Agreement (AFTA) federation members as of this package version. Static curated list; chain through verify_afta_federation(domain) to confirm live cert posture per member.
balanceGet ETH balanceread-only
Returns the native ETH balance of an address on Base mainnet.
block_numberGet latest Base block numberread-only
Returns the latest block number on Base mainnet.
callRead-only contract callread-only
Performs an eth_call against a contract on Base mainnet. Read-only; never broadcasts a transaction.
decode_x402_payment_payloadDecode an X-PAYMENT header payloadread-only
Decodes a base64-encoded X-PAYMENT header payload per the Coinbase x402 V2 spec. Returns the parsed scheme, network, x402Version, EIP-3009 authorization, and signature. Pure offline decode; no signature is verified and no network call is made.
get_tx_receiptGet transaction receiptread-only
Returns the receipt for a transaction on Base mainnet, including status, gas used, and a summary of emitted logs.
parse_x402_manifestFetch and parse a publisher's x402 manifestread-only
Fetches https://{domain}/.well-known/x402.json (or x402) and returns the structured manifest. Used to discover what an x402-paid publisher accepts (scheme, network, payTo, prices, paid endpoints).
probe_x402_endpointProbe whether a URL is x402-paidread-only
Performs a GET against an https URL and reports whether the response looks like a canonical x402-paid endpoint (HTTP 402 with a JSON body containing accepts[]). Read-only. Does not pay, does not broadcast.
recent_transfersRecent USDC transfers touching an addressread-only
Returns USDC Transfer events involving the given address over the last N blocks on Base mainnet. Direction filter: in, out, or both.
tf_payment_lookupCheck if a tx was a USDC payment to TensorFeedread-only
On-chain lookup: was this transaction hash a USDC payment to TensorFeed's canonical payment wallet (0x549c82e6bFC54bdaE9A2073744CBC2AF5D1FC6D1) on Base mainnet? Returns structured details if yes. For credit attribution and endpoint mapping, the paying agent should call https://tensorfeed.ai/api/payment/history with its bearer token.
usdc_balanceGet USDC balanceread-only
Returns the USDC balance of an address on Base mainnet (Circle native bridged USDC).
usdc_recent_payments_toRecent USDC payments to an addressread-only
Returns USDC transfers TO the given address over the last N blocks on Base mainnet. A convenience wrapper for x402 merchants verifying incoming agent payments.
verify_afta_federationAFTA certification check for a domainread-only
Calls TensorFeed's canonical AFTA certification endpoint for a domain. Returns a scored checklist of which Agent Fair-Trade Agreement tenets the domain's public surfaces satisfy. Read-only.
verify_x402_settlementVerify an x402 payment settlement on Baseread-only
Given a tx hash, expected recipient, and expected USDC amount, returns a structured verdict on whether the on-chain USDC Transfer event actually matches the claimed settlement. Use to independently verify any x402 payment receipt.
x402_publisher_healthHealth and uptime of an x402 publisherread-only
Returns the latest x402 status snapshot for a given domain from TensorFeed's canonical hourly monitor: current outcome, latency, 24h/7d uptime, and the recent series of check results. Useful for agents picking which paid publisher to depend on.
