Agent & Infrastructure

Caller E2E - x402:

Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.001, get back proof of what was paid (payer, amount, network, timestamp) and the request you sent. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Cyre Gate — before your agent pays ANY other x402 service, grade the payTo counterparty + spend shape in one cheap call. Patterns, not verdicts. Agent guide: use before non-Cyre awal x402 pay. Agent guide: https://cyre.dev/SKILL.md

Cyre Policy Check — test a proposed pay (amount, host, network, risk) against a sealed spend-policy token. Returns ok + reasons. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Lockbox Match — check a proposed pay against a sealed pre-pay lockbox (intentHash + optional pins). Catch bait-and-switch. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Remove personal information from a text before your agent stores or shares it: emails, phone numbers, names, street addresses, IDs and card numbers are replaced with labels.

Check text before your agent reads or forwards it: prompt-injection attempts aimed at AI readers, and contact details (emails, phones, handles, links). Returns flags, a risk level and a cleaned copy.

Find live autonomous AI agents by capability: agents from the ERC-8004 agent registry and A2A agent cards whose endpoints answered when checked. Returns names, descriptions and A2A/MCP endpoints.

Cyre Program Brief — novelty and age patterns for a Solana program id, with optional wallet context before first touch. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Guardian Handshake — two Passports (or two Solana addresses), one compatibility brief. Score delta, risk mismatch, overlapping patterns. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Retrieves blockchain data for tokens that have graduated from a decentralized launch platform using Bitquery infrastructure.

URL HTTP metadata receipt: server-side fetch of one public http/https URL, returning only transport metadata — HTTP status, final URL, redirect chain, content type and byte length — plus a receipt id. The response body is not returned and no content preview is stored. Single GET query parameter (url).

Which public Base network RPC endpoints are healthy right now: each one's latest block, how far behind the freshest it is, and response time. Pick a fast, in-sync node before you send.

Use when an agent or user wants a warm original affirmation plus a calm word — gentle encouragement from the Synthetic Universe. Pure compute, no upstream. Optional session id avoids repeats. Resale permitted: buyer may resell this data output at their own price.

Robinhood Radar aggregator swap-quote proxy (KyberSwap / OpenOcean).

utilpeek (Tanod) user agent: browser, OS and device from a User-Agent string, plus a bot heuristic.

Guardian Counterparty Alerts — poll up to 10 watched addresses and return only those with HIGH risk, dormant→active, or burst patterns. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Guardian Settlement Batch — grade a payer and up to 10 payout addresses, ranked by score gap vs the payer. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

AI lab funding rounds and valuations as JSON (OpenAI, Anthropic): round size, post-money valuation, rounds in talks, employee tender offers, IPO valuation targets, strategic investor commitments. Each row keeps its source URL, verification grade (primary/secondary/reported) and value type.

An ERC-8004 identity on Arc for the agent that pays: we host a correct registration file, mint the identity and hand it to the paying wallet. POST JSON {name, description, image?, services?[{name, endpoint}]}.

Make a $0.01 USDC tip through the x402 v2 flow. Returns a thank-you receipt. Lowest-friction first payment to verify x402 flow.

The x402 agent marketplace landscape (Aug 2026): where to list, price and settle on Base — venue map with live price benchmarks. Date: 2026-08-18 · Method: primary-source fetches of official pages/APIs (HTTP status + byte sizes recorded per fetch); single-page samples; some JS-rendered boards could not be enumerated and are marked as such. No venue was paid into; no accounts created. One payment returns the full text, and the creator is paid as it is used.

User-agent string parsing: browser, engine, OS, device type/vendor/model, CPU architecture, plus a likely-bot flag. For agents analyzing logs or adapting responses per client.

Returns one or more RFC 9562 version-4 UUIDs generated from the operating-system CSPRNG. Handy as a cheap, reliable endpoint to test an x402 payment flow end to end. Paid with x402: a call without payment always returns 402 with the payment terms (0.005 USDC on Base), whatever the parameters; replay with a PAYMENT-SIGNATURE (or X-PAYMENT) header. Invalid parameters return 400 without charge. Nothing is stored.
