• chain_snapshot ~146 tokens
  What is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call — no parameters required. 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 ag
• contract_guard ~187 tokens
  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: $0.02 to $0.1 USDC depending on how much of the answer the network already has. Shared: reusing an an
• demand_pledge ~151 tokens
  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.
• prediction_evidence ~263 tokens
  Returns current, sourced and machine-readable evidence supporting or contradicting a prediction-market proposition. Paid per call with x402 on Base: $0.01 to $0.05 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, a
• tereno_catalog ~91 tokens
  Free. 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.
• tereno_evidence_reference ~248 tokens
  Free. 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.
• tereno_price ~239 tokens
  Free. 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 tier
• tereno_publish Sends messages · ~577 tokens
  Free, no payment and no gas. Submit a contract bytecode fingerprint you computed yourself. 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
• tereno_receipt ~143 tokens
  Free. 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.
• token_metadata ~195 tokens
  What token is this? Read a Base token's name, symbol, decimals and total supply as one typed, cache-shared answer with block-level freshness. 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 alre
