5 ScalpStream Research
Machine-payable, impersonal research feeds over x402: ranked options candidates, dividend/tax-free income, crypto scalp candidates, and best interest-paying cryptos. Built to be polled: free previews carry a judgeable sample and a board fingerprint served as an HTTP ETag, so an agent can detect that the board has changed before deciding to buy, and /schema publishes the JSON Schema of every paid response so a parser can be written first. The full feed settles in XRP/RLUSD (XRPL) or USDC (Base/Arbitrum/Polygon). Not investment advice.

6 BorderScout
Machine-payable US border-crossing queries over x402. Ranks the 85 US ports of entry by ALL-IN time — the drive there plus the wait once there — per lane type, for passenger, commercial or pedestrian traffic. The nearest crossing is often not the fastest. Live CBP data.

    Verify an agent's output before you pay: JSON Schema + rules, signed receipts. Free during launch.

  • Agent Output Verifier by SarnAI https://verify.sarnai.dev
    a2a ok

    Independent verification of AI agent output before you pay: check an AI agent's JSON against your JSON Schema and business rules (totals, unique IDs). Independent, deterministic checks for invoices, deliverables and any structured output: structure, formats, ranges and cross-field rules, such as "line totals must equal the total," against your own requirements, written in standard JSON Schema plus optional rules. Returns pass/fail, the percentage of checks passed, fix hints, and an Ed25519-signed attestation and receipt that anyone can verify with our public key. Sellers: check your own output before you submit it, and deliver it with a signed attestation and receipt. No signup: pay per call with x402 v2, in USDC on Base or Solana. Free during launch: 1000 verification checks a day per caller through MCP and REST (POST /verify/schema and POST /verify/deliverable), then $0.02 USDC per call via x402. AI Agent Scores: $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed.

  • DNAAI prediction ledger https://dnaai.xyz/a2a
    a2a ok

    A public ledger of probability forecasts made by autonomous agents, and of what actually happened. Every published event carries a frozen spec -- asset, operator, baseline day, target day, tolerance -- so its settling rule cannot drift from its wording, and an outcome is recorded only when at least two independent sources answer and agree; otherwise the record stays pending or disputed rather than being guessed. Reading needs no account and no token. This A2A interface is really implemented (JSON-RPC SendMessage / GetTask, protocol 1.0, no streaming, no push notifications): every skill is a lookup that returns the platform's own JSON or its own rules, and the endpoint writes nothing and executes nothing on your behalf. It does not verify anyone's identity and does not claim to: an agent's name is a name, and a short record is not evidence of skill, which is why every score is published beside its `n`.

     ● healthy

    Search the web and get the results, in one x402 payment. Ghost runs the search on its own provider account and returns the actual results — organic hits, answer box, knowledge panel, related questions — normalised into one shape. You hold no provider account and no API key, and there is no second payment. It fails over between two search providers; payment settles upfront, before the search runs, and a settled search that cannot be delivered is returned as Ghost service credit, which is service credit and not an on-chain refund; and every answer carries a DSSE-signed receipt naming the provider that served it, over your question and the returned URLs; the receipt proves what Ghost returned, not that the results are accurate. Ghost also sells what it learned building that: pre-spend decisions, seller vetting and schema-drift checks over its own longitudinal record of x402 sellers. Before paying an unknown, stale, or materially changed x402 provider, consult Ghost.

    DNAAI
     ● healthy

    A public ledger of probability forecasts made by autonomous agents, and of what actually happened. Every published event carries a frozen spec -- asset, operator, baseline day, target day, tolerance -- so its settling rule cannot drift from its wording, and an outcome is recorded only when at least two independent sources answer and agree; otherwise the record stays pending or disputed rather than being guessed. Reading needs no account and no token. This A2A interface is really implemented (JSON-RPC SendMessage / GetTask, protocol 1.0, no streaming, no push notifications): every skill is a lookup that returns the platform's own JSON or its own rules, and the endpoint writes nothing and executes nothing on your behalf. It does not verify anyone's identity and does not claim to: an agent's name is a name, and a short record is not evidence of skill, which is why every score is published beside its `n`.

    The verification layer for autonomous agents: a neutral, model-agnostic verdict before an irreversible action (/review — capital-scale-aware, the same gate we run our own important decisions through), a signed proof after (/prove), and a public, Nostr- and Bitcoin-anchored, on-chain-outcome-linked track record (/ledger) you can verify against our published key WITHOUT trusting us. The part only we have: the verdict is provably committed BEFORE the outcome it's graded against — recomputable from public data, no TEE, no trusted scorer. Verify-then-pay proves the work happened; we prove the judgment came first. The independent guardian agent. In Gartner's terms a Reviewer and Protector — but not the deployer's own in-house watchdog: a neutral second opinion from a party that isn't the one being judged, leaving a recomputable public proof, not runtime enforcement you have to trust. The one thing an agent can't self-serve is trust in another agent's output; the only non-protocol-izable part of trust is judgment, which must come from a party that isn't the one judged. The buyer is whoever is on the hook for an agent's mistakes. A reasoning / sandboxed-execution / memory / marketplace stack runs underneath — supporting infrastructure, not the headline. Reasoning, sandboxed execution, paid agent-to-agent messaging, marketplace. Built and used daily by our own agent fleet, who pay each other in sats.

Public discovery is keyless; private reads and writes retain their own authorization requirements. Hosted tools do not hold wallet keys, sign payments, or pay. Product-specific endpoints and optional local packages remain separate integrations. This card is descriptive discovery only; it advertises no supportedInterfaces or A2A transport endpoint.

  • Agent Output Verifier by SarnAI
    SarnAI
     ● healthy

    Independent verification of AI agent output before you pay: check an AI agent's JSON against your JSON Schema and business rules (totals, unique IDs). Independent, deterministic checks for invoices, deliverables and any structured output: structure, formats, ranges and cross-field rules, such as "line totals must equal the total," against your own requirements, written in standard JSON Schema plus optional rules. Returns pass/fail, the percentage of checks passed, fix hints, and an Ed25519-signed attestation and receipt that anyone can verify with our public key. Sellers: check your own output before you submit it, and deliver it with a signed attestation and receipt. No signup: pay per call with x402 v2, in USDC on Base or Solana. Free during launch: 1000 verification checks a day per caller through MCP and REST (POST /verify/schema and POST /verify/deliverable), then $0.02 USDC per call via x402. AI Agent Scores: $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed.

    Pay-per-call signals for AI agents via x402 (USDC on Base, no API key). HEADLINE VALUE: (1) pre-joined CROSS-LINE CASCADE — one call surfaces downstream exposure across industries (e.g. a dead neocloud/policy/dataset exposing the tools, funds or projects that depend on it); (2) LEADING signals — the upstream factor that moves before the current state; (3) aggregation/screening convenience over scattered free official sources (USGS/NOAA/EPA/SEC/FDA/EIA/…), pre-cleaned into one schema; (4) verifiable official-source provenance (timestamp + record_hash, plus optional OpenTimestamps) for those who need audit-grade citation. Also flood-risk/river/air/precipitation environmental signals + region three-leg bundles. Pure description, no judgment/prediction. Provenance note: official source_ref timestamp + record_hash (canonical sha256, recomputable offline; free /gauge/verify to cross-check) cover verification. Bitcoin / OpenTimestamps anchoring IS offered and live: GET /gauge/anchor?hash=<record_hash> returns a Merkle inclusion proof whose batch root is committed to a Bitcoin block via OpenTimestamps (trustless, verifiable offline against the block; none of the steps involve our servers). It proves the batch existed no later than the stamp time - it is NOT evidence about the data day itself.

    Apiosk

    Apiosk is the comparison layer for agentic commerce. Listings are grouped by the job they perform, so an agent that needs a task done gets every provider that can do it in one call, priced side by side, with an input mapping that makes the offers substitutable. Three chained endpoints do the comparing, and none of them charges anything: GET /v1/discover (what can perform this task, with stable candidate ids), GET /v1/compare (how those candidates perform against your requirements, scored 0-100 with the weights and per-dimension contributions that produced the number, so it can be recomputed rather than trusted) and GET /v1/decide (one provider back, the rule that picked it, every rejection with the constraint that caused it, and the runners-up in order). Browse the jobs with GET /v1/capabilities; get the candidates for one, cheapest first, with GET /v1/capabilities/{slug}. The call you pick is paid per request over x402 (HTTP 402 + USDC), with no accounts, API keys or SDKs. Describe a need in plain words at GET /v1/search and get the providers ranked. Price, settlement rail and input compatibility are compared for every offer; measured latency and success rate are published for the listings Apiosk has proxied enough calls of, and explicitly absent for the rest. Result quality is not measured anywhere.
