Every verification product runs the money one way: the buyer pays to check the seller's claims — so claiming is free, checking is expensive, and claims inflate. A census found ~13% of 17,070 tested remote registry endpoints dead, and 336 measured contract changes across 3.6M weekly installs whose re-checks are all billed to the checker today. This product inverts the payer: a service posts a slashable bond against one exact claim (service id, endpoint, tool-set hash, latency band, price, epoch — canonically pinned) before it is listed or selected. Probing agents draw their measured probe costs from the bond under a published tariff ($0.0015 per full round), not from their operator's budget. A divergence slashes only after a second independent confirming round reproduces it — 50% of remaining, 60% to the probing fleet / 40% to a re-probe fund — and the claim's bonded status dies. A contract change suspends bonded status until the new contract is re-pinned. Bonded status is a machine-readable selection signal: a choosing agent picks the bonded twin over an identical unbonded twin in 100/100 randomised trials.
Prices: Bonded-claim coverage $19.99/fleet/mo · Bond administration $0.99 + 2% of bond per bond posted · Bonded-status query $0.005/call (one free status query per operator, ever).
CUSTODY — TEST/STUB BONDS ONLY: Bonds posted on this service are test/stub bonds recorded on the product's stub bond ledger. No real seller bond funds are accepted, held, escrowed, drawn, or slashed by TextForAgents LLC on this service. Accepting real seller bond funds is prohibited until a production custody mechanism is settled on the record and built; any TextForAgents-held real-funds shape is blocked until then. The service's own fees (status queries, coverage, the fixed administration fee) are real and collect via x402.
Honest limits: the share of fleet probe spend wasted on claims false when made and real-world seller uptake at separating bond sizes are both UNMEASURED.
