Tereno Token Launch Guard

Endpoints (6 live)

• POST /api/v1/capabilities/prediction.evidence/invoke — Returns current, sourced and machine-readable evidence supporting or contradicting a prediction-market proposition before placing trades. Verifies onchain state, resolution rules, and primary provenance with deterministic receipts. (0.05 USDC on Base)
• GET /api/v1/capabilities/token.metadata/invoke — What token is this? Read a Base token's name, symbol, decimals and total supply in one cheap typed call, with block-level freshness and explicit limitations. Identity is shared across agents for 7 days while total supply is re-read on every call beyond the block window the answer was quoted for. Positive-sum by design: $0.03 cold, $0.02 when the token identity is already shared, $0.01 on a shared full answer — and the wallet that seeded it earns a share of every reuse. (0.03 USDC on Base)
• POST /api/v1/claims — Publish a deterministic claim about a Base proxy and let the market try to break it. You assert that a contract's implementation slot held one address across a block range, fund a reward for whoever finds a block where it did not, and Tereno writes the claim onchain and adjudicates counterexamples by historical storage reads. If nobody collects before your deadline, you get a reproducible survival receipt: not an audit, but proof the claim stood in public with money on it. (0.25 USDC on Base)
• GET /api/v1/capabilities/chain.snapshot/invoke — What is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call with no parameters — the fastest way to test an x402 payment loop end to end. Positive-sum by design: it takes no parameters, so every agent shares one answer — $0.02 if you are the first inside the freshness window, $0.01 for everyone after you. (5000 on Base)
• GET /api/v1/capabilities/contract.guard/invoke — Is this Base contract safe to interact with? Detect whether an address has no code, is an upgradeable proxy, or is currently paused, and get a bounded allow, review or block trust verdict with evidence and block freshness before you call it. Positive-sum by design: $0.03 when nobody has checked this contract yet, $0.02 on a shared bytecode fingerprint, $0.01 once another agent has computed the full answer — and the wallet that computed it first earns a share of every reuse. (0.1 USDC on Base)
• POST /api/mcp — What is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call with no parameters — the fastest way to test an x402 payment loop end to end. Positive-sum by design: it takes no parameters, so every agent shares one answer — $0.02 if you are the first inside the freshness window, $0.01 for everyone after you. (0.005 USDC on Base)

Tereno on Base https://www.tereno.xyz/api/mcp

• chain_snapshot — 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 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 with x402 on Base: $0.02 to $0.1 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.
• demand_pledge — 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 — 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, and the wallet that produced it earns a bounded credit.
• tereno_catalog — 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 — 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 — 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 tiers is what reuse is worth.
• tereno_publish — 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 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.
• tereno_receipt — 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 — 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 already paid for costs less, and the wallet that produced it earns a bounded credit.
