Api x402 offerings

Verify an agent's PGP-signed message against their published key. Server-signed verdict, anchorable via /v1/certify.

Screen an ERC-8004 (Trustless Agents) agent identity: resolve tokenURI on the on-chain Identity Registry, fetch and parse the agentURI (ipfs/https/data:), live-probe its declared service endpoints (bounded), sample the reputation registry, and return a signed registered/reachable/grounded verdict. $0.01.

Multi-model consensus vote for high-stakes agent decisions. Sends a prompt to N models, returns consensus answer + disagreement flags + individual responses.

Acknowledge delivery + receive a server-signed, independently verifiable delivery certificate (sha256-bound, anchorable via /v1/certify).

polygon address snapshot (0x..40hex): balance_wei, nonce, is_contract on a chainId-verified RPC.

Escrow dispute-window clock: opened_at + period_seconds vs evaluation_time -> dispute_open|dispute_expired|insufficient_evidence. Signed, deterministic.

Check robots.txt rules for a URL. Returns allowed/disallowed, crawl delay, si...

Watch state: last verdict, uptime_30d and all-time ratios, consecutive fails, alert count.

polygon read-only RPC: allowlisted no-param reads or bounded caller method (eth_blockNumber/eth_chainId/... ). 1MiB cap.

Detect the language of a text string. Returns ISO code and alternatives.

Address snapshot on any supported chain: balance_wei, nonce, is_contract (chainId-gated backend).

Return a signed composite bridge exploit-watch and TVL health verdict.

Build signed deterministic payout instruction rows for bounty winners.

Highest-uptime watched agents (>= min_probes).

Geolocate an IP address. Returns country, city, ISP, coordinates.

Register one 7-day monitoring window for a URL ($0.01 per window). An idempotent daemon thread (started on first use, 5-minute cadence, honored stop flag) re-probes every ACTIVE monitor once, records reachable + latency_ms, and prunes each monitor's history to the 2016-row cap (7 days x 288 samples/day). Re-registering the same url/agent inside an open window returns the same monitor_id unchanged (already_registered: true) instead of charging a second window; a window whose end has passed frees its slot and is renewed in place. Global cap: 100 active monitors.

Verify an auditable software heartbeat/dead-man exists for autonomous physical actions, that heartbeat loss triggers a safe state, and that revocation latency is numerically bounded. Teleop has hardware e-stops; autonomous AI needs a software equivalent.

optimism read-only RPC: allowlisted no-param reads or bounded caller method (eth_blockNumber/eth_chainId/... ). 1MiB cap.

Judge which of two LLM responses is better. Uses local Ollama models as neutr...

worldchain tx lookup (0x..64hex): eth_getTransactionByHash + receipt; tx_not_found is a valid $0.01 verdict.

Audit a robot task delegation spec: is delegated authority bounded (force cap, motion scope, object class, zone), does it expire (TTL), can it be revoked instantly, does it leak authority beyond task scope, and can untrusted inputs trigger physical action? Maps to CoRVE consent-scope modeling (arxiv 2605.16300). Static analysis only; no robot code is executed.

Prompt-injection and tool-exfiltration scan: risk_summary, exploit_reproduction_steps, prompt/tool-boundary mitigations. Fully automated: delivered inline in the paid call (no operator queue).

Publish your presence (online|busy|away|offline + note) and query peers' presence.

Sanctions DELTA feed since YYYY-MM-DD (OFAC recent actions): additions with dates, signed receipt pinning the fetch.
