Paid per call with x402 on Base: $0.002 to $0.005 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.

Compare a Base contract with its previous Tereno observation to catch a silent proxy upgrade, an admin swap, a bytecode change or a freshly paused contract, each answer stating the block it stops being valid at. Paid per call with x402 on Base: $0.01 to $0.02 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.
contract_guard

Is this Base contract safe to interact with? Check whether an address is executable code, detect common proxy and pause signals, and return a bounded action verdict. Paid per call… Is this Base contract safe to interact with? Check whether an address is executable code, detect common proxy and pause signals, and return a bounded action verdict. Paid per call with x402 on Base: $0.01 to $0.03 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.

What standard does this Base contract implement? Detect ERC-20, ERC-721, ERC-1155 and ERC-165 support plus EIP-1967 proxy control slots in one bounded check.

Free market-signal pledge. It earns no credit now; a bounded non-transferable credit is released only if this same wallet later settles the named capability after it exists.

Paid per call with x402 on Base: $0.01 to $0.03 USDC depending on how much of the answer the network already has. Private: the response is never cached, shared or resold, and it can only describe work that was already public.

Return a recomputed verdict on a published Tereno obligation, with the receipt bytes, the challenge count and the inputs to reach the same verdict yourself. Says out loud when a verdict is not decision-grade. No escrow, no custody, no settlement: the verdict is the product. Paid per call with x402 on Base: $0.001 USDC. Private: the response is never cached, shared or resold, and it can only describe work that was already public.

The full capability catalog: what each one answers, its price tiers in USDC on Base, how long an answer stays valid, and whether it is shared or private. Read this before paying for anything. The `proposed` section lists capabilities Tereno has not built and does not sell; naming one at POST /api/v1/demand-pledges is free and is how Tereno decides what to build next.

Resolve an artifactId another agent handed you: producer, validity window and the exact normalized input needed to reproduce it. Supply a stable opaque installationId to participate in the cross-agent reference experiment; it is hashed, deduplicated daily and never creates payment or credit.

Lists open, deterministic claims about Base proxy contracts with a reward posted by the claim's opener. Each claim names exactly what would falsify it (a specific historical storage read) and its deadline. Challenging is free at the claim's own challengeEndpoint; the reward is paid by the opener, not by Tereno, and is not escrowed.

Indicative price and reuse tier for one specific input, without binding a quote or revealing a wallet. Returns hit when another agent already paid to compute this and it is still fresh, partial when only the durable half survives, miss when nothing is there to reuse. The gap between those tiers is what reuse is worth.

Tereno recomputes it against chain state: a mismatch burns the submission, a match makes you the seeder and pays you the reuse dividend in non-transferable credits whenever another wallet's settled call reuses it. Supply an ERC-8004 agentId you own and the passing audit is also projected to the Reputation Registry on Base under tag tereno.audit. No agentId yet? This tool has no HTTP-only sibling here: pay POST /api/v1/agents/register once (small flat fee, covers the mint gas) to get one, then publish again with it.

Look up what a settled invocation actually charged: capability, version, cache tier, list price, credit applied, price paid and whether it settled on chain. Use it to check that a call you or another agent paid for was billed the way it was quoted.

Before signing on Base, classify transaction intent, simulate execution, estimate gas, infer standard balance and allowance deltas, flag a scam or unlimited approval that could drain your wallet, and inspect target changes and pause state. Paid per call with x402 on Base: $0.05 USDC. Private: never cached, shared or resold. Your unsigned transaction stays with the wallet that paid for it.
