Agent & Infrastructure

Statistical analysis of any segment of the x402 economy, computed over a merged index of Coinbase Bazaar and 402index overlaid with our own unpaid 402 probes. Returns the full price distribution (min, p10, p25, median, p75, p90, max, mean), demand discounted by payer concentration, what share of the segment can actually be invoked, the network and asset split, host concentration, liveness, and — once history exists — the trend. Every figure is computed in code from named rows;

Competitive position for a single x402 resource. Give a URL that is listed anywhere in the merged index and get back what the index holds on it (including any correction our own unpaid 402 probe made to its advertised price), the peer set derived from its own description, and where it ranks among those peers on price, call volume, payer diversity and callability — plus the mirrors of itself that are listed as separate services.

Model Desk: Agents Need Run State. vLLM, Gemini Managed Agents, Mistral Studio, and Robostral Navigate all pushed the same operational question this week: what state does an agent carry, and who can audit it later? One payment returns the full text, and the creator is paid as it is used.

Proof agents need verifier rails. Leanstral 1.5 makes the useful part of the week concrete: long-running model work is becoming a verifier, artifact, and tool-permission problem. One payment returns the full text, and the creator is paid as it is used.

The X1 Agent Registry (ERC-8004 for SVM, which APEX deployed on X1 on 27 Sep 2026), in full: every registered agent with its owner, registration file and the live check of every endpoint it lists (MCP handshake, A2A card, x402 paywall and the networks it accepts, web), whether it can be paid on X1, feedback counts and the registration transaction. Rescanned every 30 minutes; the answer states its age and the count, which is small because the registry is new.

Every agent registered on Arc (ERC-8004 identity registry) with its agentId, owner and registration file — the full directory of who is operating on Arc, read from the chain. The free endpoint returns only the count and the first few.

Local insider tips for ski and mountain travel from people on the ground, each with its resort, country and date (e.g. early glacier snowpark openings). One payment returns every current tip; ?id=<tip-id> returns one. Tips are in the local language (currently Slovak), plain text.

Cyre Session Ticket — require a fresh Passport or Decision Receipt before your agent proceeds. Checks signature, expiry, max age, optional address + risk ceiling. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Intent Seal — hash your intent locally, seal it before you pay or sign, then match it on /api/receipt. Stops bait-and-switch. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Host Brief — before you pay a resource URL, measure host hygiene (https, IP host, TLD shape, self-pay). No historical blacklist — patterns only. Agent guide: https://cyre.dev/SKILL.md

Cyre Intent Lockbox — seal your intentHash before you pay so any party can later prove the hash was locked pre-settle. Bearer holds the token. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Lookalike — before your agent sends funds, check whether the destination looks like one of your known contacts (prefix/suffix traps, near-edits, confusable chars). Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Pay-route Oracle — before your agent pays any external x402 resource, grade payTo + amount/URL + facilitator/offer pin hygiene in one call. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Guardian Intent Exchange match — compare a sealed intent token to a vendor quote (URL, payTo, amount). Returns fit brief + next skills. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Cyre Spend Policy — seal max spend, allow/deny hosts, networks, and risk ceiling into a signed policy token other agent middleware can enforce. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

Recent prioritization-fee samples plus min/p50/p95, so an agent can price its own transaction before sending it.

x402 validator: will Coinbase Bazaar list your x402 endpoint, and can a client pay it? Why will Coinbase not list your x402 endpoint, and can a standard client pay it? Pass ?url= (and &method=POST for a POST route). We read its 402 as a client does, check what Coinbase's facilitator and Bazaar enforce (accepts[0] network, the $0.001 minimum, descriptions over 500 characters, a bazaar schema that must describe info, query numbers typed as strings, routeTemplate, exposed headers), and ask…

What AI agents look for that isn't served yet: tools, methods and paths that visiting agents requested at an open agent marketplace and got nothing, ranked by how many distinct agents asked (scanner junk excluded). Build what's missing.

Scores live market evidence coverage, source availability, cross-source validation and retained trend-window availability. Purpose: Give downstream agents an inspectable quality gate before they rely on Edge Agents market evidence. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

Why x402scan shows zero transactions on a server that is paid correctly. If you run an x402 resource server, settle payments correctly, and still see a flat zero on your x402scan dashboard, the explanation is almost always attribution, not a lost payment. I hit this on a production x402 resource server where money was arriving on-chain exactly as designed and the explorer still credited us with nothing. Here is what is actually happening, verified as of July 2026 against the Merit-Systems/x402scan indexer behavior. x402scan builds its picture of a server from two thi. One payment returns the full text, and the creator is paid as it is used.

Paid $0.05 USDC exact on Base: structured x402 honesty report. Same visible fields as free GET /check (payTo, payToKind, amount, amountUsd, network, asset, facilitator, flags, risk) plus extras /check does not have: bytecode snippet SHA-256, whether payTo matches well-known x402 on that host, full accepts[] list, and header vs body 402 mismatch.

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.
