jurat: signed evidence and x402 conformance for AI agents

Why there is no number here.
Below the publication floor, MCP Scores publishes no grade and no numeric score. NR is not a favorable or adverse finding.
- archive coverage is 2 day(s); 7 are required
- successful observations are 2; 3 are required
Earliest eligible publication date: 2026-08-17, if observation continues without interruption.
NR is not a favorable or adverse finding. The measured components below are model inputs, published as diagnostics with their own stated denominators — they are not a rating.
Decomposition
Five components. No hidden blend.
Component values run 0–100 and are measured, not modelled. The weight shown is that component's share of the 0–1000 composite for this listing type. The composite they feed is withheld until the publication floor is met.
Evidence ledger
What was actually observed.
Every line separates a measured statement from its source table, its coverage confidence, and its observation date. No line infers motive or intent.
| Measured statement | Source | Confidence | Observed as of |
|---|---|---|---|
| First observed 2026-08-11; last observed 2026-08-12; 2 archive day(s); 2 successful observation(s). | D1 resource_history + probes | limited coverage | |
| Served a qualifying HTTP response on 1/1 probes; returned any HTTP response on 1/1; valid payment challenge observed on 0/1. | D1 probes | limited coverage | |
| Seller-owned domain registration date observed as 2026-07-20. | R2 RDAP enrichment | RDAP supplied | |
| No parseable x402 payment terms were captured. | R2 enrichment record | single latest record | |
| No listing metadata change day has been recorded since first observation. | D1 resource_history | archive history | |
| The host published llms.txt when checked. | R2 enrichment record | single latest record |
Material observations and score constraints
No valid x402 payment challenge was observed on the unpaid probes; the endpoint may require a different method or path.
D1 probes · measured with protocol limitation · Aug 12, 2026 UTCThe observed seller-owned domain registration date is less than 90 days old.

Inflow, diversity, concentration.
Inbound USDC transfers observed inside a disclosed Base block range. MCP Scores never labels a balance or an observed inflow as operator revenue, and a wallet declaration does not establish legal ownership.

Declared payee: not captured · declared on — listing(s)
Wallet balance snapshot: not available
No observed flow record. This does not mean zero activity; it means no wallet-flow scan currently covers this declared payee.
Longitudinal record
History, with the missing history visible.
Stored engine rating records are archive material only; the current rating above is the single authoritative figure and is recomputed read-only. No stored record is withheld from this series.
Stored engine score records
Internal Model 1.0 sweep records held in D1. These are engine diagnostics; the public figure is always the live recomputation shown above.
No engine rating record has been stored for this listing yet. The archive has to run a rating sweep before a history exists.

Coverage & limitations
What this report can — and cannot — support.
This report describes observed data at stated times. It does not allege intent or misconduct and is not an endorsement, guarantee, security audit, or transaction recommendation.
Included now
- Rotating HTTP probes and latest endpoint enrichment
- Archive tenure and listing-change days
- Declared payment terms and available Base USDC observations
Limitations
- The score is an ordinal Model 1.0 output, not a calibrated probability of failure.
- Unpaid checks measure reachability and protocol responses; they do not prove paid delivery.
- A score is not an endorsement, security audit, guarantee, or transaction recommendation.
- The observation archive spans 2 calendar day(s) (2026-08-11 through 2026-08-12), with observations recorded on 2 day(s). No 30-day or 90-day trend, survival estimate, or forward horizon can be supported by an archive of that length.
- No declared payee wallet was available for on-chain flow observation.
Pending model inputs
- Cross-wallet funding-source analysis
- Cohort survival percentile after sufficient archive age
- Wallet-funded delivery verification
- 90-day probability calibration and quarterly backtest
Corrections and appeals

An accepted correction is recorded in the observatory action log and rendered on this scorecard, in this JSON payload, and in the MCP tool response, dated and attributed to MCP Authority.
