Tollex bronze

Plan a paid capability

Find the capability that fits a need under the given constraints, with its route and maximum price and a reason code for every rejected candidate. Never spends. Data part: {skill, need, input?, constraints?}.

• {"skill":"tollex.resolve_intent","need":"ETH-USD spot price","input":{"pair":"ETH-USD"},"constraints":{"maxCost":"5000"}}

Buy and run a capability

Resolve a need, then buy the selected capability with x402 (a2a-x402 flow): the first reply is a payment-required task naming the capability; re-send with the signed payment to execute. Data part: {skill, need, input, constraints?}.

• {"skill":"tollex.execute_intent","need":"ETH-USD spot price","input":{"pair":"ETH-USD"}}

Purchase status

Execution, settlement and reconciliation state of a purchase. Use it instead of paying again when an outcome is unclear. Data part: {skill, operationId}.

• {"skill":"tollex.operation","operationId":"<operation id>"}

Get transaction

Transaction by hash: sender, recipient, value, nonce, type, calldata size and inclusion block. (price 7900 atomic USDG via x402 exact)

Get receipt

Transaction receipt with observed settlement assurance (l2_included → l2_confirmed → parent_safe → parent_finalized), canonicality re-check and confirmations. (price 7900 atomic USDG via x402 exact)

Get logs

Event logs for a contract over a bounded block range (max range enforced), optionally filtered by topic0. (price 7900 atomic USDG via x402 exact)

Contract read

Read-only call of one view/pure function given its human-readable ABI signature, at a pinned block. (price 7900 atomic USDG via x402 exact)

Simulate call

Simulate a call against current state (eth_call). Never broadcasts. Returns return data or the revert reason/selector. (price 7900 atomic USDG via x402 exact)

Get code

Runtime bytecode hash and size for an address; detects EIP-7702 delegated EOAs (0xef0100 prefix) and ERC-1967 proxies. (price 7900 atomic USDG via x402 exact)

Estimate gas

Gas estimate plus current base fee and priority fee, with the implied maximum cost in wei. Never broadcasts. (price 7900 atomic USDG via x402 exact)

Native ETH balance

ETH (gas asset) balance and transaction count of an address on Robinhood Chain. (price 7900 atomic USDG via x402 exact)

Token balance

ERC-20 balance (atomic units + decimals) of an address; defaults to USDG. (price 7900 atomic USDG via x402 exact)

Allowance

ERC-20 allowance from owner to spender (default spender: canonical Permit2). Permit2-based x402 payments need this allowance in place. (price 7900 atomic USDG via x402 exact)

EIP-3009 authorization state

Whether an EIP-3009 authorization nonce has been used (authorizationState). On USDG a replayed authorization does not revert, so use this check rather than a simulation to detect consumed authorizations. (price 7900 atomic USDG via x402 exact)

Token activity

Recent ERC-20 Transfer events into and out of an address (default token USDG) over a bounded block window. (price 7900 atomic USDG via x402 exact)

USDG metadata

USDG (Paxos Global Dollar) on Robinhood Chain: address, name, symbol, decimals, total supply and current ERC-1967 implementation. (price 7900 atomic USDG via x402 exact)

USDG EIP-712 domain

USDG EIP-712 signing domain and on-chain DOMAIN_SEPARATOR, with a byte-for-byte reconstruction check. (price 7900 atomic USDG via x402 exact)

USDG capability probe

Live, facet-aware verification of USDG EIP-3009/EIP-2612/EIP-712 capability and x402 contract bytecode on Robinhood Chain (read-only). (price 7900 atomic USDG via x402 exact)

USDG authorization state

authorizationState(authorizer, nonce) on USDG. This is the authoritative replay check, because USDG replays do not revert. (price 7900 atomic USDG via x402 exact)

Inspect x402 endpoint

Fetch a resource unpaid (SSRF-guarded) and decode its x402 v2 challenge: resource info, accepts[], extensions, latency and accepts hash. (price 7900 atomic USDG via x402 exact)

Get payment requirements

FRESH payment requirements for a resource (never cached; historical listings are not payment terms). (price 7900 atomic USDG via x402 exact)

Validate requirements

Validate x402 v2 payment requirements (given inline or fetched from a URL) against CAIP-2, atomic amounts, the pinned asset and EIP-712 domain of each network (USDG on Robinhood Chain, USDC on Base) and scheme-specific extras. (price 7900 atomic USDG via x402 exact)

Simulate payment

Pre-flight a payment WITHOUT signing: requirement validity, payer USDG balance, Permit2 allowance (for Permit2/upto), and whether gas-sponsored approval is offered. (price 7900 atomic USDG via x402 exact)

Facilitator status

A facilitator's live /supported and /ready (SSRF-guarded), or the status of Tollex's configured facilitator mesh. (price 7900 atomic USDG via x402 exact)

Reconciliation check

Read-only reconciliation check of a Tollex payment operation: durable state vs. chain evidence for its settlement transaction. (price 7900 atomic USDG via x402 exact)

Stock Token quote

Multiplier-adjusted Stock Token mid price with halt and staleness checks; returns an input hash to commit into receipts. This is a price input only; payments settle in USDC on Base or USDG on Robinhood Chain. (price 7900 atomic USDG via x402 exact)

Stock Token halt status

Whether a Stock Token's underlying is in a trading halt, with the quote generation time. (price 7900 atomic USDG via x402 exact)

Stock Token corporate actions

Processed corporate actions (splits, cash/stock dividends) that change Stock Token multipliers, optionally for one symbol. (price 7900 atomic USDG via x402 exact)

Inspect merchant
