fresh402_check Observe document changes ~1,249
Observes public documents without modifying their source. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials and with evaluation:true omitted, a valid call returns an unpaid quote without executing the observation. Use Check for on-demand changed/unchanged, hash, cache status and optional text diff across sessions. Exactly one url or real watch_id; URL/rules can create a watch, while watch_id reuses rules and forbids overrides. Save returned ID/hash. First URL observation may return changed:null. max_age_seconds defaults0 (conditional revalidation); positive age permits cached evidence. html_attributes observes selected same-text attribute changes. Public HTTPS, no JavaScript or scheduler. Use Smart Diff for structured changes, or direct HTTP if you retain both versions. Walletless first Check: require root instant_evaluation.enabled, then set evaluation:true with valid URL/watch input. One attempt per verified network prefix per approved period, sharing finite capacity; no wallet, key, custom header or proprietary SDK. Exact replay returns retained evidence, not a new fetch;429 never authorizes payment. $0.005 USDC/call on Base (eip155:8453), including cache hits. Needs an x402-capable MCP payment client and funded native-USDC payer; ordinary MCP returns a payment challenge. Optional MPP (root mpp_payments.enabled): mppx, org.paymentauth/credential. Prepaid: X-Fresh402-API-Key plus params._meta["fresh402/prepaid"] {idempotency_key,tariff_version,max_credits}; inspect authenticated quote. Choose one billing method; never auto-pay. Persist original proof/input/private recovery token; recover originals after uncertainty. Circle only if root circle_gateway.enabled. Clients, limits and recovery: https://fresh402.com/docs#payments. Free signed trial: /v3/agent-trial requires an unfunded EOA ownership signature; human Web trial: /v2/trial. Eli…

{"include_diff":true,"max_age_seconds":0,"selector":"main","url":"https://example.com/docs"}fresh402_contract_watch Observe contract state ~656
Reads blockchain state; the observation does not execute transactions or modify the target wallet/contract. An authorized USDC service payment is separate. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials, a valid call returns an unpaid quote without executing the observation. Observe code, standard proxy slots, common getters, explicitly selected storage/ABI and bounded selected events at one finalized Base address; optionally compare an owned prior snapshot. Selected single-provider evidence only; unknown controls remain unknown. $0.010000 native USDC/call on Base (eip155:8453); compatible x402 or enabled native MPP client required, no Fresh402 token for first purchase. Save proof/input and private recovery token BEFORE paying for full-response-loss protection: REST X-Fresh402-Recovery-Token; MCP params._meta['fresh402/recovery-token']. Recover originals without new RPC/debit; foreign snapshot/cursor forbidden. Provider failure/partial scan is not paid success. observation_saved=false/persistence_error: recover only, never use unsaved IDs. Prepaid needs eligible finalized all-service credits or an original explicit service-specific tariff4 grant; inspect /v3/prepaid/quote/contract_watch and /v3/prepaid/all-services. Historical Web rights unchanged; paying agents do not need their own RPC credentials. Observations30days, private financial recovery7days. Not full history, financial advice or security audit. Clients: https://fresh402.com/docs#payments. Free signed trial: /v3/agent-trial requires an unfunded EOA ownership signature; human Web trial: /v2/trial. Eligibility/capacity may return429. Use only X-Fresh402-Trial-Key plus persisted Idempotency-Key; replay exact tool/input/key. Exhaustion never authorizes a charge.

fresh402_extract Extract public document content ~1,260
Observes public documents without modifying their source. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials, a valid call returns an unpaid quote without executing the observation. Use Extract for text, metadata, headings, links, JSON-LD and content hash from one public document; no watch required. No comparison, crawl or JavaScript. CSS scopes HTML; json_pointer selects one JSON value, json_pointers selects1-8 ordered fields; missing selections fail422. feed_mode:entries projects bounded RSS2/Atom; omit for XML-as-text. max_chars defaults20000, clips text but not the full hash; clipped structured data is omitted. For repeat observations use Check, then separately authorize Extract if needed. A local reader may suffice for one-off reads. $0.01 USDC/call on Base (eip155:8453), including cache hits. Needs an x402-capable MCP payment client and funded native-USDC payer; ordinary MCP returns a payment challenge. Optional MPP (root mpp_payments.enabled): mppx, org.paymentauth/credential.

Observes public documents without modifying their source. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials, a valid call returns an unpaid quote without executing the observation. Use for bounded directional OpenAPI3.0/3.1 JSON contract-change evidence, including supported paths/operations, required fields, types/enums/null and authentication. Requires real watch_id from free unfiltered registration; no URL override. compare_to: previous(default) or baseline; previous_hash overrides with supported retained evidence. First call seeds contract history. No YAML, external-reference fetch or endpoint execution; uncertainty requires review, not a complete compatibility proof. Save watch IDs; local oasdiff may suit larger contracts. $0.020 USDC/call on Base (eip155:8453), including cache hits. Needs an x402-capable MCP payment client and funded native-USDC payer; ordinary MCP returns a payment challenge. Optional MPP (root mpp_payments.enabled): mppx, org.paymentauth/credential.

fresh402_register Register a free document baseline ~579
Observes public content without modifying its source. Adds a Fresh402 baseline and uses free registration capacity for new watches; never charges USDC or credits. Use free ($0) Register to save a public HTTPS baseline; no trial key, wallet or payment. Required url plus optional content/attribute rules identifies the watch. Save returned watch_id/hash for Check, Smart Diff or OpenAPI Contract Diff. Same URL/rules returns existing state without fetching or refreshing; different rules identify another watch. It is not continuous monitoring. HTML/JSON/text only; no JavaScript, private or authenticated targets. DNS/fetch/quota limits apply, including on repeat calls. For walletless first Check inspect root instant_evaluation.enabled and set evaluation:true; separate /v3/agent-trial requires ownership signing. Connection grants no signing or payment authority.

Observes public documents without modifying their source. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials, a valid call returns an unpaid quote without executing the observation. Use Smart Diff for bounded JSON Pointer/HTML block changes and deterministic significance evidence across sessions. Requires real registered watch_id; fetches using saved rules. compare_to: previous(default) or baseline; previous_hash overrides with compatible retained same-watch evidence. json_array_keys explicitly matches unique typed identities; ambiguity fails. No cache-age option or scheduler. Missing history404; truncated/incompatible baseline409. Not complete semantic proof.
