Solana text-to-speech API with fixed-price tiers paid via x402. Converts text input into a hosted audio URL. This endpoint is a fixed-price tier: '/solana/tts/100' charges exactly 1.000000 USDC prepaid. Within this tier, you can send up to 1666 characters (including spaces). If you send more, the server returns HTTP 400 and you should use a higher-priced /solana/tts/<amount> tier.

Decision procedure for an agent deciding whether a discovered API capability is real, indexed, and safe to pay before it authorizes settlement. Input: candidate endpoint or capability index entry, claimed tool/function name, price, discoverability source (well-known file, MCP server, capability registry, market catalog). Step 1 verify the index entry resolves: endpoint responds, 402 challenge or documented auth exists, no 404/405/tiny-body stub. Step 2 check capability match: claimed function

Deterministic gate for an agent presented with an issuer-signed agent identity credential or identity tag before transacting. Ordered checks: issuer trust (who signed, verification key published, issuer linked to rail or facilitator), key binding via proof of possession against the session signing key, non-transferability (no reuse across agents, resale signals forgery), revocation and expiry checked before and at settlement, scope binding (a tag asserts identity, not payment authority), and replay protection via session nonce. Outputs ACCEPT, ACCEPT_WITH_CAVEATS, REQUIRE_ISSUER_CONFIRMATION, or REJECT with the failing check named.

Decision procedure for outbound agent-to-human notifications. Given a notification class (critical alert, approval request, daily digest, invoice dispute, system event), returns: channel selection (Slack, MS Teams, email, SMS, dashboard), urgency tier, response-time budget, message richness, audit retention, escalation trigger when unacknowledged, fanout rules, and per-channel cost. Thresholds are concrete, not vibes: severity maps to channel, latency budget maps to escalation cadence, audit

query -> up to 10 deduped, rendered sources as one token-budgeted bundle (~8,000 tokens combined). Combines /search (three-provider failover, region=tw Taiwan lane) with /content's rendered-page fetching internally, so you get one call instead of assembling search-then-fetch yourself. Sources are deduped by domain. Requires at least 3 successfully fetched sources to succeed -- returns sources_requested and sources_returned so you can see how many of the candidate set actually came back.

Decision procedure for agents that are offered prepaid credit packages by x402 merchants (Browser Use + Coinbase style credit purchases, or any merchant selling prepaid balances). Inputs: credit package price, credits included, effective per-call cost vs the merchant's pay-per-verified-call price, expiry window, minimum purchase size, refund or transfer terms, merchant operational history, whether the merchant publishes a balance attestation the agent can verify, and the remaining task budget.

Decision procedure for merchants converting an existing API-key or subscription-billed API to keyless x402 pay-per-call. Answers the conversion questions in order: which endpoints migrate first based on usage data and abuse risk, how to wire HTTP 402 PAYMENT-REQUIRED with payment-signature verification per request, how to rate-limit and set abuse thresholds when there is no user identity to key on, how to price per endpoint with floor and ceiling bounds, how to run shadow mode with dual billing

Paid agent-facing brief on per-rail fee and settlement-speed ranking procedure for agent x402 settlement: a deterministic decision procedure that converts measured per-rail fee observations and settlement-speed observations into a ranked rail order for an agent's next settlement, with data-collection steps, normalization across rails with different units (gas vs fee vs priority), staleness rules for observations, and a tie-break ladder. Distinct from route selection (which picks a rail given an

Decision procedure for an agent whose interface or curated content feed may be reached by minors. Classifies exposure into three classes (direct minor signal, mixed-age public audience, age-agnostic internal tool), runs restricted-category screening on the content or action (mature, addictive-pattern, personalized-recommendation, financial, self-harm adjacent), and decides refuse, sandbox, or deliver-with-disclosure per class. Applies jurisdiction override under strict minor-protection rules
